[Serhii Iliushyk]

The list of updates provided by the patchset:
  * Multiple TX and RX queues.
  * Scattered and gather for TX and RX.
  * RSS hash
  * RSS key update
  * RSS based on VLAN or 5-tuple.
  * RSS using different combinations of fields: L3 only, L4 only or both, and
      source only, destination only or both.
  * Several RSS hash keys, one for each flow type.
  * Default RSS operation with no hash key specification.
  * VLAN filtering.
  * RX VLAN stripping via raw decap.
  * TX VLAN insertion via raw encap.
  * Flow API.
  * Multiple process.
  * Tunnel types: GTP.
  * Tunnel HW offload: Packet type, inner/outer RSS, IP and UDP checksum
      verification.
  * Support for multiple rte_flow groups.
  * Encapsulation and decapsulation of GTP data.
  * Packet modification: NAT, TTL decrement, DSCP tagging
  * Traffic mirroring.
  * Jumbo frame support.
  * Port and queue statistics.
  * RMON statistics in extended stats.
  * Flow metering, including meter policy API.
  * Link state information.
  * CAM and TCAM based matching.
  * Exact match of 140 million flows and policies.
  * Basic stats
  * Extended stats
  * Flow metering, including meter policy API.

[PATCH v1 27/73] net/ntnic: add SLC LR module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Slicer for Local Retransmit module can cut of the head a packet
before the packet leaves the FPGA RX pipeline.
This is used when the TX pipeline is configured
to add a new head in the packet.

Signed-off-by: Danylo Vodopianov <dvo-plv@napatech.com>

[PATCH v1 30/73] net/ntnic: add KM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Key Matcher module checks the values of individual fields of a packet.
It supports both exact match which is implemented with a CAM,
and wildcards which is implemented with a TCAM.

[PATCH v1 31/73] net/ntnic: add hash API

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Hasher module calculates a configurable hash value
to be used internally by the FPGA.
The module support both Toeplitz and NT-hash.

[PATCH v1 32/73] net/ntnic: add TPE module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The TX Packet Editor is a software abstraction module,
that keeps track of the handful of FPGA modules
that are used to edit packets in the TX pipeline.

[PATCH v1 33/73] net/ntnic: add FLM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v1 34/73] net/ntnic: add flm rcp module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v1 39/73] net/ntnic: add GMF (Generic MAC Feeder) module

[Serhii Iliushyk]

The Generic MAC Feeder module provides a way to feed data
to the MAC modules directly from the FPGA,
rather than from host or physical ports.
The use case for this is as a test tool and is not used by NTNIC.
This module is requireqd for correct initialization

[PATCH v1 47/73] net/ntnic: add RPP LR module

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The RX Packet Process for Local Retransmit module can add bytes
in the FPGA TX pipeline, which is needed when the packet increases in size.
Note, this makes room for packet expansion,
but the actual expansion is done by the modules.

[PATCH v1 48/73] net/ntnic: add MOD SLC LR

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The Slicer for Local Retransmit module can cut of the head a packet
before the packet leaves the FPGA RX pipeline.
This is used when the TX pipeline is configured
to add a new head in the packet

[PATCH v1 49/73] net/ntnic: add Tx CPY module

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Copy module writes data to packet fields based on the lookup
performed by the FLM module.
This is used for NAT and can support other actions based
on the RTE action MODIFY_FIELD.

[PATCH v1 57/73] net/ntnic: added flm stat interface

[Serhii Iliushyk]

[PATCH v1 58/73] net/ntnic: add tsm module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

tsm module which operate with timers
in the physical nic was added.

Necessary defines and implementation were added.

The Time Stamp Module controls every aspect of packet timestamping,
including time synchronization, time stamp format, PTP protocol, etc.

[PATCH v1 69/73] net/ntnic: add thread termination

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Introduce clear_pdrv to unregister driver
from global tracking.

Modify drv_deinit to call clear_pdirv and ensure
safe termination.

Add flm sta and age event free.

+Flow Scanner
+------------
+
+Flow Scanner is DPDK mechanism that constantly and periodically scans the RTE flow tables to check for aged-out flows.
+When flow timeout is reached, i.e. no packets were matched by the flow within timeout period,
+``RTE_ETH_EVENT_FLOW_AGED`` event is reported, and flow is marked as aged-out.
+
+Therefore, flow scanner functionality is closely connected to the RTE flows' ``age`` action.
+
+There are list of characteristics that ``age timeout`` action has:
+    - functions only in group > 0;
+    - flow timeout is specified in seconds;
+    - flow scanner checks flows age timeout once in 1-480 seconds, therefore, flows may not age-out immediately, depedning on how big are intervals of flow scanner mechanism checks;
+    - aging counters can display maximum of **n - 1** aged flows when aging counters are set to **n**;
+    - overall 15 different timeouts can be specified for the flows at the same time (note that this limit is combined for all actions, therefore, 15 different actions can be created at the same time, maximum limit of 15 can be reached only across different groups - when 5 flows with different timeouts are created per one group, otherwise the limit within one group is 14 distinct flows);
+    - after flow is aged-out it's not automatically deleted;
+    - aged-out flow can be updated with ``flow update`` command, and its aged-out status will be reverted;

[PATCH v1 72/73] net/ntnic: add meter module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Meter module was added:
1. add/remove profile
2. create/destroy flow
3. add/remove meter policy
4. read/update stats

eth_dev_ops struct was extended with ops above.

[PATCH v2 00/73] Provide flow filter API and statistics

[Serhii Iliushyk]

The list of updates provided by the patchset:
  * Multiple TX and RX queues.
  * Scattered and gather for TX and RX.
  * RSS hash
  * RSS key update
  * RSS based on VLAN or 5-tuple.
  * RSS using different combinations of fields: L3 only,
    L4 only or both, and source only, destination only or both.
  * Several RSS hash keys, one for each flow type.
  * Default RSS operation with no hash key specification.
  * VLAN filtering.
  * RX VLAN stripping via raw decap.
  * TX VLAN insertion via raw encap.
  * Flow API.
  * Multiple process.
  * Tunnel types: GTP.
  * Tunnel HW offload: Packet type, inner/outer RSS,
    IP and UDP checksum verification.
  * Support for multiple rte_flow groups.
  * Encapsulation and decapsulation of GTP data.
  * Packet modification: NAT, TTL decrement, DSCP tagging
  * Traffic mirroring.
  * Jumbo frame support.
  * Port and queue statistics.
  * RMON statistics in extended stats.
  * Flow metering, including meter policy API.
  * Link state information.
  * CAM and TCAM based matching.
  * Exact match of 140 million flows and policies.
  * Basic stats
  * Extended stats
  * Flow metering, including meter policy API.

Use of pthread_mutex makes the driver unportable to Windows, and
will block the the thread in case of contention. And it will not
handle the case of primary/secondary process.

Prefer use of DPDK spinlock if possible.

Hi Stephen!


The current version of our PMD supports only Linux x86_64 platforms.
Due to this, we have added a special condition to the meson.build file:

```
if not is_linux or not dpdk_conf.has('RTE_ARCH_X86_64')
build = false
reason = 'only supported on x86_64 Linux'
subdir_done()
endif
```

We prefer to use pthread for the current patch set and fix it later.

Best regards,
Serhii


NOTE: Please ignore the disclaimer. We are working on fix it.

[PATCH v2 27/73] net/ntnic: add SLC LR module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Slicer for Local Retransmit module can cut of the head a packet
before the packet leaves the FPGA RX pipeline.
This is used when the TX pipeline is configured
to add a new head in the packet.

Signed-off-by: Danylo Vodopianov <dvo-plv@napatech.com>

[PATCH v2 30/73] net/ntnic: add KM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Key Matcher module checks the values of individual fields of a packet.
It supports both exact match which is implemented with a CAM,
and wildcards which is implemented with a TCAM.

[PATCH v2 31/73] net/ntnic: add hash API

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Hasher module calculates a configurable hash value
to be used internally by the FPGA.
The module support both Toeplitz and NT-hash.

[PATCH v2 32/73] net/ntnic: add TPE module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The TX Packet Editor is a software abstraction module,
that keeps track of the handful of FPGA modules
that are used to edit packets in the TX pipeline.

[PATCH v2 33/73] net/ntnic: add FLM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v2 34/73] net/ntnic: add flm rcp module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v2 39/73] net/ntnic: add GMF (Generic MAC Feeder) module

[Serhii Iliushyk]

The Generic MAC Feeder module provides a way to feed data
to the MAC modules directly from the FPGA,
rather than from host or physical ports.
The use case for this is as a test tool and is not used by NTNIC.
This module is requireqd for correct initialization

[PATCH v2 47/73] net/ntnic: add RPP LR module

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The RX Packet Process for Local Retransmit module can add bytes
in the FPGA TX pipeline, which is needed when the packet increases in size.
Note, this makes room for packet expansion,
but the actual expansion is done by the modules.

[PATCH v2 49/73] net/ntnic: add Tx CPY module

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Copy module writes data to packet fields based on the lookup
performed by the FLM module.
This is used for NAT and can support other actions based
on the RTE action MODIFY_FIELD.

[PATCH v2 51/73] net/ntnic: add Tx RPL module

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Replacer module can replace a range of bytes in a packet.
The replacing data is stored in a table in the module
and will often contain tunnel data.

[PATCH v2 55/73] net/ntnic: add rpf module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Receive Port FIFO module controls the small FPGA FIFO
that packets are stored in before they enter the packet processor pipeline.

[PATCH v2 58/73] net/ntnic: add tsm module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

tsm module which operate with timers
in the physical nic was added.

Necessary defines and implementation were added.

The Time Stamp Module controls every aspect of packet timestamping,
including time synchronization, time stamp format, PTP protocol, etc.

[PATCH v2 69/73] net/ntnic: add thread termination

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Introduce clear_pdrv to unregister driver
from global tracking.

Modify drv_deinit to call clear_pdirv and ensure
safe termination.

Add flm sta and age event free.

+Flow Scanner
+------------
+
+Flow Scanner is DPDK mechanism that constantly and periodically scans the RTE flow tables to check for aged-out flows.
+When flow timeout is reached, i.e. no packets were matched by the flow within timeout period,
+``RTE_ETH_EVENT_FLOW_AGED`` event is reported, and flow is marked as aged-out.
+
+Therefore, flow scanner functionality is closely connected to the RTE flows' ``age`` action.
+
+There are list of characteristics that ``age timeout`` action has:
+    - functions only in group > 0;
+    - flow timeout is specified in seconds;
+    - flow scanner checks flows age timeout once in 1-480 seconds, therefore, flows may not age-out immediately, depedning on how big are intervals of flow scanner mechanism checks;
+    - aging counters can display maximum of **n - 1** aged flows when aging counters are set to **n**;
+    - overall 15 different timeouts can be specified for the flows at the same time (note that this limit is combined for all actions, therefore, 15 different actions can be created at the same time, maximum limit of 15 can be reached only across different groups - when 5 flows with different timeouts are created per one group, otherwise the limit within one group is 14 distinct flows);
+    - after flow is aged-out it's not automatically deleted;
+    - aged-out flow can be updated with ``flow update`` command, and its aged-out status will be reverted;

[PATCH v2 72/73] net/ntnic: add meter module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Meter module was added:
1. add/remove profile
2. create/destroy flow
3. add/remove meter policy
4. read/update stats

eth_dev_ops struct was extended with ops above.

[Serhii Iliushyk]

The list of updates provided by the patchset:
  * Multiple TX and RX queues.
  * Scattered and gather for TX and RX.
  * RSS hash
  * RSS key update
  * RSS based on VLAN or 5-tuple.
  * RSS using different combinations of fields: L3 only,
    L4 only or both, and source only, destination only or both.
  * Several RSS hash keys, one for each flow type.
  * Default RSS operation with no hash key specification.
  * VLAN filtering.
  * RX VLAN stripping via raw decap.
  * TX VLAN insertion via raw encap.
  * Flow API.
  * Multiple process.
  * Tunnel types: GTP.
  * Tunnel HW offload: Packet type, inner/outer RSS,
    IP and UDP checksum verification.
  * Support for multiple rte_flow groups.
  * Encapsulation and decapsulation of GTP data.
  * Packet modification: NAT, TTL decrement, DSCP tagging
  * Traffic mirroring.
  * Jumbo frame support.
  * Port and queue statistics.
  * RMON statistics in extended stats.
  * Flow metering, including meter policy API.
  * Link state information.
  * CAM and TCAM based matching.
  * Exact match of 140 million flows and policies.
  * Basic stats
  * Extended stats
  * Flow metering, including meter policy API.

[PATCH v3 27/73] net/ntnic: add SLC LR module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Slicer for Local Retransmit module can cut of the head a packet
before the packet leaves the FPGA RX pipeline.
This is used when the TX pipeline is configured
to add a new head in the packet.

Signed-off-by: Danylo Vodopianov <dvo-plv@napatech.com>

[PATCH v3 30/73] net/ntnic: add KM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Key Matcher module checks the values of individual fields of a packet.
It supports both exact match which is implemented with a CAM,
and wildcards which is implemented with a TCAM.

[PATCH v3 31/73] net/ntnic: add hash API

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Hasher module calculates a configurable hash value
to be used internally by the FPGA.
The module support both Toeplitz and NT-hash.

[PATCH v3 32/73] net/ntnic: add TPE module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The TX Packet Editor is a software abstraction module,
that keeps track of the handful of FPGA modules
that are used to edit packets in the TX pipeline.

[PATCH v3 33/73] net/ntnic: add FLM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v3 34/73] net/ntnic: add flm rcp module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v3 39/73] net/ntnic: add GMF (Generic MAC Feeder) module

[Serhii Iliushyk]

The Generic MAC Feeder module provides a way to feed data
to the MAC modules directly from the FPGA,
rather than from host or physical ports.
The use case for this is as a test tool and is not used by NTNIC.
This module is requireqd for correct initialization

[PATCH v3 47/73] net/ntnic: add RPP LR module

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The RX Packet Process for Local Retransmit module can add bytes
in the FPGA TX pipeline, which is needed when the packet increases in size.
Note, this makes room for packet expansion,
but the actual expansion is done by the modules.

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The Slicer for Local Retransmit module can cut of the head a packet
before the packet leaves the FPGA RX pipeline.
This is used when the TX pipeline is configured
to add a new head in the packet

[PATCH v3 49/73] net/ntnic: add Tx CPY module

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Copy module writes data to packet fields based on the lookup
performed by the FLM module.
This is used for NAT and can support other actions based
on the RTE action MODIFY_FIELD.

[PATCH v3 51/73] net/ntnic: add Tx RPL module

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Replacer module can replace a range of bytes in a packet.
The replacing data is stored in a table in the module
and will often contain tunnel data.

Avoid use of rte_memcpy(), it has less checking that memcpy().
The only place it can make sense is in the hot data path where compiler is more
conservative about alignment.

Use structure assignment instead of memcpy() to keep type checking.

Use RTE_MIN() and the key_len variable should not be signed.

Since dev_private is void *, no need for the cast here (in C code).

In general, this code is good about moving declarations next to first use.
But here res is initialized to 0 but then set again from hasher_fields.
Why not just move the declaration there.

[PATCH v3 54/73] net/ntnic: add statistics API

[PATCH v3 55/73] net/ntnic: add rpf module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Receive Port FIFO module controls the small FPGA FIFO
that packets are stored in before they enter the packet processor pipeline.

[PATCH v3 69/73] net/ntnic: add termination thread

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Introduce clear_pdrv to unregister driver
from global tracking.

Modify drv_deinit to call clear_pdirv and ensure
safe termination.

Add flm sta and age event free.

+Flow Scanner
+------------
+
+Flow Scanner is DPDK mechanism that constantly and periodically scans the RTE flow tables to check for aged-out flows.
+When flow timeout is reached, i.e. no packets were matched by the flow within timeout period,
+``RTE_ETH_EVENT_FLOW_AGED`` event is reported, and flow is marked as aged-out.
+
+Therefore, flow scanner functionality is closely connected to the RTE flows' ``age`` action.
+
+There are list of characteristics that ``age timeout`` action has:
+    - functions only in group > 0;
+    - flow timeout is specified in seconds;
+    - flow scanner checks flows age timeout once in 1-480 seconds, therefore, flows may not age-out immediately, depedning on how big are intervals of flow scanner mechanism checks;
+    - aging counters can display maximum of **n - 1** aged flows when aging counters are set to **n**;
+    - overall 15 different timeouts can be specified for the flows at the same time (note that this limit is combined for all actions, therefore, 15 different actions can be created at the same time, maximum limit of 15 can be reached only across different groups - when 5 flows with different timeouts are created per one group, otherwise the limit within one group is 14 distinct flows);

[PATCH v3 72/73] net/ntnic: add meter module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Meter module was added:
1. add/remove profile
2. create/destroy flow
3. add/remove meter policy
4. read/update stats

eth_dev_ops struct was extended with ops above.

[PATCH v4 00/86] Provide flow filter API and statistics

[Serhii Iliushyk]

The list of updates provided by the patchset:
  - FW version
  - Speed capabilities
  - Link status (Link update only)
  - Unicast MAC filter
  - Multicast MAC filter
  - Promiscuous mode (Enable only. The device always run promiscuous mode)
  - Multiple TX and RX queues.
  - Scattered and gather for TX and RX.
  - RSS hash
  - RSS key update
  - RSS based on VLAN or 5-tuple.
  - RSS using different combinations of fields: L3 only, L4 only or both, and
      source only, destination only or both.
  - Several RSS hash keys, one for each flow type.
  - Default RSS operation with no hash key specification.
  - VLAN filtering.
  - RX VLAN stripping via raw decap.
  - TX VLAN insertion via raw encap.
  - Flow API.
  - Multiple process.
  - Tunnel types: GTP.
  - Tunnel HW offload: Packet type, inner/outer RSS, IP and UDP checksum
      verification.
  - Support for multiple rte_flow groups.
  - Encapsulation and decapsulation of GTP data.
  - Packet modification: NAT, TTL decrement, DSCP tagging
  - Traffic mirroring.
  - Jumbo frame support.
  - Port and queue statistics.
  - RMON statistics in extended stats.
  - Flow metering, including meter policy API.
  - Link state information.
  - CAM and TCAM based matching.
  - Exact match of 140 million flows and policies.
  - Basic stats
  - Extended stats
  - Flow metering, including meter policy API.
  - Flow update. Update of the action list for specific flow
  - Asynchronous flow API
  - MTU update

Update: the pthread API was replaced with RTE spinlock in the separate patch.

There is no clear way to set this build time configuration, hence easy
to miss testing it which leads to dead/broken code by time.
That is why it is better to convert these compile time configuration to
dynamic configuration.

For this set, are you OK to go with default value of the macro, for
SCATTER_GATHER as far as I can see it is defined by default?

Same for FLOW_DEBUG below. I can see it is used for log, in that case
dynamic logging should be used.

Hi Ferruh

Please find below the description of NT FPGA profiles.

The Napatech adapters support more different functionality than can fit into a single FPGA.
This functionality is grouped into a number of profiles called inline, capture, vswitch, and basic.
The adapter support we aim to upstream this time around, is for the inline profile.
The code contains some of the structures and enums needed to add other profiles,
mainly for future compatibility, and for compatibility with our legacy code base.

Here is a short description of each profile:
Inline: Uses a scatter gather packet system, which is quite fast and lightweight.
The FPGA contains functionality for hardware offload use-cases, such as stateful flow matching,
encap/decap, packet steering etc.
vSwitch: Also uses the scatter gather system. The FPGA features are selected to support
the functionality of OVS.
Capture: Uses Napatech’s proprietary packet buffer system,
which requires a lot of space on the FPGA, but is extremely fast, guarantees zero packet loss,
and zero copy packet handling on the host cpu.
Basic: The same feature set as one might expect from a basic nic.
Mostly used in Kubernetes containers to reduce complexity.

Re: [PATCH v4 05/86] net/ntnic: add minimal NT flow inline profile

> Hi Ferruh
> 
> Please find below the description of NT FPGA profiles.
> 
> The Napatech adapters support more different functionality than can fit into a single FPGA.
> This functionality is grouped into a number of profiles called inline, capture, vswitch, and basic.
> The adapter support we aim to upstream this time around, is for the inline profile.
> The code contains some of the structures and enums needed to add other profiles,
> mainly for future compatibility, and for compatibility with our legacy code base.
> 
> Here is a short description of each profile:
> Inline: Uses a scatter gather packet system, which is quite fast and lightweight.
> The FPGA contains functionality for hardware offload use-cases, such as stateful flow matching,
> encap/decap, packet steering etc.
> vSwitch: Also uses the scatter gather system. The FPGA features are selected to support
> the functionality of OVS.
> Capture: Uses Napatech’s proprietary packet buffer system,
> which requires a lot of space on the FPGA, but is extremely fast, guarantees zero packet loss,
> and zero copy packet handling on the host cpu.
> Basic: The same feature set as one might expect from a basic nic.
> Mostly used in Kubernetes containers to reduce complexity.
> 

Thanks Serhii,

It is good to have this information in the driver documentation, and I
will reflect some of this in to the relevant commit log.

[PATCH v4 27/86] net/ntnic: add SLC LR module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Slicer for Local Retransmit module can cut of the head a packet
before the packet leaves the FPGA RX pipeline.
This is used when the TX pipeline is configured
to add a new head in the packet.

Signed-off-by: Danylo Vodopianov <dvo-plv@napatech.com>

[PATCH v4 30/86] net/ntnic: add KM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Key Matcher module checks the values of individual fields of a packet.
It supports both exact match which is implemented with a CAM,
and wildcards which is implemented with a TCAM.

[PATCH v4 31/86] net/ntnic: add hash API

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Hasher module calculates a configurable hash value
to be used internally by the FPGA.
The module support both Toeplitz and NT-hash.

[PATCH v4 32/86] net/ntnic: add TPE module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The TX Packet Editor is a software abstraction module,
that keeps track of the handful of FPGA modules
that are used to edit packets in the TX pipeline.

[PATCH v4 33/86] net/ntnic: add FLM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v4 34/86] net/ntnic: add flm rcp module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v4 39/86] net/ntnic: add GMF (Generic MAC Feeder) module

[Serhii Iliushyk]

The Generic MAC Feeder module provides a way to feed data
to the MAC modules directly from the FPGA,
rather than from host or physical ports.
The use case for this is as a test tool and is not used by NTNIC.
This module is requireqd for correct initialization

[PATCH v4 47/86] net/ntnic: add RPP LR module registers

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The RX Packet Process for Local Retransmit module can add bytes
in the FPGA TX pipeline, which is needed when the packet increases in size.
Note, this makes room for packet expansion,
but the actual expansion is done by the modules.

[PATCH v4 49/86] net/ntnic: add Tx CPY module registers

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Copy module writes data to packet fields based on the lookup
performed by the FLM module.
This is used for NAT and can support other actions based
on the RTE action MODIFY_FIELD.

[PATCH v4 51/86] net/ntnic: add Tx RPL module registers

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Replacer module can replace a range of bytes in a packet.
The replacing data is stored in a table in the module
and will often contain tunnel data.

[PATCH v4 69/86] net/ntnic: add termination thread

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Introduce clear_pdrv to unregister driver
from global tracking.

Modify drv_deinit to call clear_pdirv and ensure
safe termination.

Add flm sta and age event free.

+    - overall 15 different timeouts can be specified for the flows at the same time (note that this limit is combined for all actions, therefore, 15 different actions can be created at the same time, maximum limit of 15 can be reached only across different groups - when 5 flows with different timeouts are created per one group, otherwise the limit within one group is 14 distinct flows);
+    - after flow is aged-out it's not automatically deleted;
+    - aged-out flow can be updated with ``flow update`` command, and its aged-out status will be reverted;

Similar comment as previous, please merge this patch with the patch that
introduces the flow aging functionality.

Same for "meter documentation" patch, "documentation for flow actions
update" patch, "flow API documentation" patch and "documentation for set
MTU" patch.

[PATCH v4 71/86] net/ntnic: add meter API

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Add meter API and implementation to the profile inline.

management functions were extended with meter flow support.

[PATCH v4 72/86] net/ntnic: add meter module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Meter module was added:
1. add/remove profile
2. create/destroy flow
3. add/remove meter policy
4. read/update stats

eth_dev_ops struct was extended with ops above.

[PATCH v4 83/86] net/ntnic: add async template APIs implementation

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

flow filter ops and inline API was exnteded with next APIs:
1. flow pattern template create
2. flow pattern template destroy
3. flow actions template create
4. flow actions template destroy
5. flow template table create
6. flow template table destroy

Hi Serhii,

After each patch, driver should build fine, this is required for git
bisect testing, but in this patch series build fails after some patches,
can you please check?

Also a minor comment, in some patch titles 'API' is used, in DPDK scope
API is functions exposed from library to application use, so almost all
use of API is wrong, can you please update them?
Like "net/ntnic: add flow filter API" can become "net/ntnic: support
flow filter"

[PATCH v5 00/80] Provide flow filter and statistics support

[Serhii Iliushyk]

The list of updates provided by the patchset:
  - FW version
  - Speed capabilities
  - Link status (Link update only)
  - Unicast MAC filter
  - Multicast MAC filter
  - Promiscuous mode (Enable only. The device always run promiscuous mode)
  - Flow API support.
  - Support for multiple rte_flow groups.
  - Multiple TX and RX queues.
  - Scattered and gather for TX and RX.
  - Jumbo frame support.
  - Traffic mirroring.
  - VLAN filtering.
  - Packet modification: NAT, TTL decrement, DSCP tagging
  - Tunnel types: GTP.
  - Encapsulation and decapsulation of GTP data.
  - RX VLAN stripping via raw decap.
  - TX VLAN insertion via raw encap.
  - CAM and TCAM based matching.
  - Exact match of 140 million flows and policies.
  - Tunnel HW offload: Packet type, inner/outer RSS, IP and UDP checksum
    verification.
  - RSS hash
  - RSS key update
  - RSS based on VLAN or 5-tuple.
  - RSS using different combinations of fields: L3 only, L4 only or both, and
    source only, destination only or both.
  - Several RSS hash keys, one for each flow type.
  - Default RSS operation with no hash key specification.
  - Port and queue statistics.
  - RMON statistics in extended stats.
  - Link state information.
  - Flow statistics
  - Flow aging support
  - Flow metering, including meter policy API.
  - Flow update. Update of the action list for specific flow
  - Asynchronous flow support
  - MTU update

Update: the pthread API was replaced with RTE spinlock in the separate patch.

[PATCH v5 27/80] net/ntnic: add SLC LR module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Slicer for Local Retransmit module can cut of the head a packet
before the packet leaves the FPGA RX pipeline.
This is used when the TX pipeline is configured
to add a new head in the packet.

Signed-off-by: Danylo Vodopianov <dvo-plv@napatech.com>

[PATCH v5 30/80] net/ntnic: add KM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Key Matcher module checks the values of individual fields of a packet.
It supports both exact match which is implemented with a CAM,
and wildcards which is implemented with a TCAM.

[PATCH v5 31/80] net/ntnic: add hash API

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Hasher module calculates a configurable hash value
to be used internally by the FPGA.
The module support both Toeplitz and NT-hash.

[PATCH v5 33/80] net/ntnic: add FLM module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v5 34/80] net/ntnic: add FLM RCP module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.

[PATCH v5 39/80] net/ntnic: add GMF (Generic MAC Feeder) module

[Serhii Iliushyk]

The Generic MAC Feeder module provides a way to feed data
to the MAC modules directly from the FPGA,
rather than from host or physical ports.
The use case for this is as a test tool and is not used by NTNIC.
This module is requireqd for correct initialization

[PATCH v5 47/80] net/ntnic: add RPP LR module registers

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The RX Packet Process for Local Retransmit module can add bytes
in the FPGA TX pipeline, which is needed when the packet increases in size.
Note, this makes room for packet expansion,
but the actual expansion is done by the modules.

[PATCH v5 48/80] net/ntnic: add SLC LR module registers

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The Slicer for Local Retransmit module can cut of the head a packet
before the packet leaves the FPGA RX pipeline.
This is used when the TX pipeline is configured
to add a new head in the packet

[PATCH v5 49/80] net/ntnic: add Tx CPY module registers

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Copy module writes data to packet fields based on the lookup
performed by the FLM module.
This is used for NAT and can support other actions based
on the RTE action MODIFY_FIELD.

[PATCH v5 51/80] net/ntnic: add Tx RPL module registers

[Serhii Iliushyk]

From: Oleksandr Kolomeiets <okl-plv@napatech.com>

The TX Replacer module can replace a range of bytes in a packet.
The replacing data is stored in a table in the module
and will often contain tunnel data.

[PATCH v5 55/80] net/ntnic: add rpf module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Receive Port FIFO module controls the small FPGA FIFO
that packets are stored in before they enter the packet processor pipeline.

+Flow Scanner
+        ------------
+
+        Flow Scanner is DPDK mechanism that constantly and periodically scans the RTE flow tables to check for aged-out flows.
+        When flow timeout is reached, i.e. no packets were matched by the flow within timeout period,
+        ``RTE_ETH_EVENT_FLOW_AGED`` event is reported, and flow is marked as aged-out.
+
+        Therefore, flow scanner functionality is closely connected to the RTE flows' ``age`` action.
+
+        There are list of characteristics that ``age timeout`` action has:
+        - functions only in group > 0;
+        - flow timeout is specified in seconds;
+        - flow scanner checks flows age timeout once in 1-480 seconds, therefore, flows may not age-out immediately, depedning on how big are intervals of flow scanner mechanism checks;
+        - aging counters can display maximum of **n - 1** aged flows when aging counters are set to **n**;
+        - overall 15 different timeouts can be specified for the flows at the same time (note that this limit is combined for all actions, therefore, 15 different actions can be created at the same time, maximum limit of 15 can be reached only across different groups - when 5 flows with different timeouts are created per one group, otherwise the limit within one group is 14 distinct flows);
+        - after flow is aged-out it's not automatically deleted;
+        - aged-out flow can be updated with ``flow update`` command, and its aged-out status will be reverted;

[PATCH v5 68/80] net/ntnic: add termination thread

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Introduce clear_pdrv to unregister driver
from global tracking.

Modify drv_deinit to call clear_pdirv and ensure
safe termination.

Add flm sta and age event free.

Signed-off-by: Danylo Vodopianov <dvo-plv@napatech.com>

[PATCH v5 70/80] net/ntnic: add meter module

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

Meter module was added:
1. add/remove profile
2. create/destroy flow
3. add/remove meter policy
4. read/update stats

eth_dev_ops struct was extended with ops above.

[PATCH v5 75/80] net/ntnic: remove unnecessary

[Serhii Iliushyk]

Type casting:
	The dev_private has type void * and type casting is not necessary.
FLOW_DEBUG condition
	Use the dynamic logging

[PATCH v5 79/80] net/ntnic: add async template implementation

[Serhii Iliushyk]

From: Danylo Vodopianov <dvo-plv@napatech.com>

flow filter ops and inline API was exnteded with next APIs:
1. flow pattern template create
2. flow pattern template destroy
3. flow actions template create
4. flow actions template destroy
5. flow template table create
6. flow template table destroy
