[dpdk-dev] [PATCH 00/17] bugfixes and small functionality for hns3

[Lijun Ou]

This patch series add some bugfixes and some small
functions. In order to fix some bugfixes, we had to
do some code rework, for example patch[13/17].

Chengchang Tang (6):
  net/hns3: support module EEPROM dump
  net/hns3: add more registers to dump
  net/hns3: fix stats flip overflow
  net/hns3: replace all atomic type with C11 atomic builtins
  net/hns3: fix cmdq cleared during firmware process
  net/hns3: fix VF reset after MBX failed

Chengwen Feng (4):
  net/hns3: implement cleanup for Tx done
  net/hns3: constraint TM peak rate
  net/hns3: remove MPLS type from supported flow items
  net/hns3: fix FD rule residue in hardware when malloc fail

Huisong Li (5):
  net/hns3: fix query order of link status and link info
  net/hns3: fix link status change from firmware
  net/hns3: encapsulate a port shaping interface
  net/hns3: support PF on electrical net device
  net/hns3: add check for max pkt length of Rx

Lijun Ou (1):
  net/hns3: fix RSS indirection table size

Min Hu (Connor) (1):
  net/hns3: add enhance stats function

[dpdk-dev] [PATCH 04/17] net/hns3: add enhance stats function

[Lijun Ou]

From: "Min Hu (Connor)" <humin29@huawei.com>

In current HNS3 PMD, Rx/Tx bytes and imissed from
packet stats are not implemented.

This patch implemented Rx/Tx bytes using soft counters.
Rx/Tx bytes stats will be enabled if the macro
RTE_LIBRTE_HNS3_PMD_SOFT_COUNTERS is defined. Also,
Rx imissed stats was in implemented in this patch.

[dpdk-dev] [PATCH 05/17] net/hns3: fix query order of link status and link info

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

When link information is updated in the firmware, the link information
is updated first and then the link status is updated. In a 1s periodic
task, PF driver queries the link information and then obtains link status.
It may lead to a 1s time difference for obtaining valid link information
when the port is up. Therefore, the query order of driver should be
reversed to the order of firmware.

Fixes: 59fad0f32135 ("net/hns3: support link update operation")

[dpdk-dev] [PATCH 06/17] net/hns3: fix link status change from firmware

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

When the hardware link status changes, the firmware proactively
reports the link status change message, and then driver update
link status. This feature is lack of a switch to control in pf
driver. Otherwise, this feature does not take effect when the
kernel PF driver that supports the feature is not loaded.

When rate of port changes, the rate limit of the port needs to
be updated. So it is necessary to encapsulate an interface that
configures the rate limit based on the rate.

[dpdk-dev] [PATCH 08/17] net/hns3: support PF on electrical net device

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

The normal operation of electrical interface devices depends on the
initialization and configuration of the PHY chip. The task of driving
the PHY chip is implemented in some firmware versions. If firmware
supports the phy driver, it will report a capability flag to driver
in probing process. The driver determines whether to support electrical
device based on the capability bit. If supported, the driver set a flag
indicating that the firmware takes over the PHY, and then the firmware
intializes the PHY.

This patch supports the query of link status and link info, and existing
basic features for electrical device.

[dpdk-dev] [PATCH 09/17] net/hns3: fix RSS indirection table size

[Lijun Ou]

the driver should not use the fixed value as the validity check of
RSS indirection table size with HW supported. As a result, it will
cause misjudgment when the RSS reta size with HW supported have
changed.

Fixes: c37ca66f2b27 ("net/hns3: support RSS")

[dpdk-dev] [PATCH 10/17] net/hns3: constraint TM peak rate

[Lijun Ou]

From: Chengwen Feng <fengchengwen@huawei.com>

User could config Port or TC's peak rate by TM ops, but hardware does
not support peak rate which lower than 1Mbps. So we constraint tm
peak rate must be at least 1Mbps.

[dpdk-dev] [PATCH 12/17] net/hns3: fix stats flip overflow

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, statistics may overflow in some scenarios.

For example, if HW statistics are reset by stats reset operation,
but there are still a lot of residual packets exist in the HW
queues and these packets are error packets, flip may occurred
because the ipacket is obtained by substracting the number of
software error packets from the number of HW received packets.

This patch verifies the calculation and returns 0 when overflow
may occur.

[dpdk-dev] [PATCH 15/17] net/hns3: fix cmdq cleared during firmware process

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

There are two scenarios that command queue uninit performed
concurrently with the firmware command: asynchronous command
and timeout command.

For asynchronous command, if a large number of functions send
commands, these commands may need to be queued to wait for
firmware processing. If a function is uninited suddenly, CMDQ
clearing and firmware processing may be performed concurrently.

For timeout command, if the command failed due to busy scheduling
of firmware, this command will be processed in the next scheduling.
And this may lead to concurrency.

The preceding concurrency may lead to a firmware exceptions.

This patch add a waiting time to ensure the firmware complete the
processing of left over command when PMD uninit.

[dpdk-dev] [PATCH 16/17] net/hns3: fix VF reset after MBX failed

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, during the VF reset, the VF will send a MBX to inform
PF to reset it and the disable command bit will be set whether
the MBX is successful. Generally, multiple reset attempts are made
after a failure. However, because the command is diabled, all
subsequent reset will all fail.

This patch disable the command only after the MBX message is
successfully.

[dpdk-dev] [PATCH 17/17] net/hns3: add check for max pkt length of Rx

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

When jumbo frame is enabled, the MTU size needs to be modified
based on 'max_rx_pkt_len'. Driver needs to check the validity
of 'max_rx_pkt_len'. And it should be in the range of
HNS3_DEFAULT_FRAME_LEN and HNS3_MAX_FRAME_LEN. Otherwise, it may
cause that the MTU size is inconsistent with jumbo frame offload.

Hi Lijun,

Is this for next release or current release?
We are a day away from the -rc3 and a week (almost) away from the actual 
release, it is safer to limit the patches to fixes at this stage.

If above set is for this release, can you please make a new version to have only 
fixes, and leave the new supports and refactoring and not important fixes to 
next release?

Thanks,
ferruh

Yes, I've been aware of our expectations and requirements of each rc. 
Therefore, we have selected some new support items that have been 
developed and tested in the roadmap and hope to integrate them in the 
rc3. Some key bug fixes are expected to be fixed in the current version 
as soon as possible.

Still not sure about getting new small functionality in the last day of the 
-rc3, what do you think get the fixes and push the new functionality to next 
release?

Technically new features should be sent _before_ the proposal deadline, December 
20, and we are more flexible for the drivers but there should be a deadline 
eventually.
