[PATCH 1/3] common/iavf: support raw packet in protocol header

[Junfeng Guo]

The patch extends existing virtchnl_proto_hdrs structure to allow VF
to pass a pair of buffers as packet data and mask that describe
a match pattern of a filter rule. Then the kernel PF driver is requested
to parse the pair of buffer and figure out low level hardware metadata
(ptype, profile, field vector.. ) to program the expected FDIR or RSS
rules.

INTERNAL ONLY:

This is requirement from DPDK to support Protocol Agnostic Flow
Offloading(*1). Previously we have integrated the Parser Library(*2)
into DPDK and enabled a raw packet based FDIR and RSS support in DPDK
PF driver(*3,*4), to enable the same feature for AVF driver, we need
Virtual Channel to support raw packet filter rule passing.

[PATCH 2/3] net/iavf: align with proto hdr struct change

[Junfeng Guo]

Structure virtchnl_proto_headrs is extended with a union struct for
proto_hdr table and raw struct. Thus update the proto_hdrs template
init to align the virtchnl changes.

[PATCH v2 1/3] common/iavf: support raw packet in protocol header

[Junfeng Guo]

The patch extends existing virtchnl_proto_hdrs structure to allow VF
to pass a pair of buffers as packet data and mask that describe
a match pattern of a filter rule. Then the kernel PF driver is requested
to parse the pair of buffer and figure out low level hardware metadata
(ptype, profile, field vector.. ) to program the expected FDIR or RSS
rules.

INTERNAL ONLY:

This is requirement from DPDK to support Protocol Agnostic Flow
Offloading(*1). Previously we have integrated the Parser Library(*2)
into DPDK and enabled a raw packet based FDIR and RSS support in DPDK
PF driver(*3,*4), to enable the same feature for AVF driver, we need
Virtual Channel to support raw packet filter rule passing.

[PATCH v2 2/3] net/iavf: align with proto hdr struct change

[Junfeng Guo]

Structure virtchnl_proto_headrs is extended with a union struct for
proto_hdr table and raw struct. Thus update the proto_hdrs template
init to align the virtchnl changes.

[PATCH v3 1/3] common/iavf: support raw packet in protocol header

[Junfeng Guo]

The patch extends existing virtchnl_proto_hdrs structure to allow VF
to pass a pair of buffers as packet data and mask that describe
a match pattern of a filter rule. Then the kernel PF driver is requested
to parse the pair of buffer and figure out low level hardware metadata
(ptype, profile, field vector.. ) to program the expected FDIR or RSS
rules.

INTERNAL ONLY:

This is requirement from DPDK to support Protocol Agnostic Flow
Offloading(*1). Previously we have integrated the Parser Library(*2)
into DPDK and enabled a raw packet based FDIR and RSS support in DPDK
PF driver(*3,*4), to enable the same feature for AVF driver, we need
Virtual Channel to support raw packet filter rule passing.

[PATCH v3 2/3] net/iavf: align with proto hdr struct change

[Junfeng Guo]

Structure virtchnl_proto_headrs is extended with a union struct for
proto_hdr table and raw struct. Thus update the proto_hdrs template
init to align the virtchnl changes.

[PATCH v4 1/4] common/iavf: support raw packet in protocol header

[Junfeng Guo]

The patch extends existing virtchnl_proto_hdrs structure to allow VF
to pass a pair of buffers as packet data and mask that describe
a match pattern of a filter rule. Then the kernel PF driver is requested
to parse the pair of buffer and figure out low level hardware metadata
(ptype, profile, field vector.. ) to program the expected FDIR or RSS
rules.

[PATCH v4 2/4] net/iavf: align with proto hdr struct change

[Junfeng Guo]

Structure virtchnl_proto_headrs is extended with a union struct for
proto_hdr table and raw struct. Thus update the proto_hdrs template
init to align the virtchnl changes.

[PATCH v5 1/4] common/iavf: support raw packet in protocol header

[Junfeng Guo]

The patch extends existing virtchnl_proto_hdrs structure to allow VF
to pass a pair of buffers as packet data and mask that describe
a match pattern of a filter rule. Then the kernel PF driver is requested
to parse the pair of buffer and figure out low level hardware metadata
(ptype, profile, field vector.. ) to program the expected FDIR or RSS
rules.

proto_hdr table and raw struct. Thus update the proto_hdrs template
init to align the virtchnl changes.

[PATCH v5 3/4] net/iavf: enable Protocol Agnostic Flow Offloading FDIR

[Junfeng Guo]

This patch enabled Protocol Agnostic Flow (raw flow) Offloading Flow
Director (FDIR) in AVF, based on the Parser Library feature and the
existing rte_flow `raw` API.

The input spec and mask of raw pattern are first parsed via the
Parser Library, and then passed to the kernel driver to create the
flow rule.

Similar as PF FDIR, each raw flow requires:
1. A byte string of raw target packet bits.
2. A byte string contains mask of target packet.

Here is an example:
FDIR matching ipv4 dst addr with 1.2.3.4 and redirect to queue 3:

flow create 0 ingress pattern raw \
pattern spec \
00000000000000000000000008004500001400004000401000000000000001020304 \
pattern mask \
000000000000000000000000000000000000000000000000000000000000ffffffff \
/ end actions queue index 3 / mark id 3 / end

Note that mask of some key bits (e.g., 0x0800 to indicate ipv4 proto)
is optional in our cases. To avoid redundancy, we just omit the mask
of 0x0800 (with 0xFFFF) in the mask byte string example. The prefix
'0x' for the spec and mask byte (hex) strings are also omitted here.

[PATCH v5 4/4] net/iavf: support Protocol Agnostic Flow Offloading VF RSS

[Junfeng Guo]

From: Ting Xu <ting.xu@intel.com>

Enable Protocol Agnostic Flow Offloading for RSS hash in VF. It supports
raw pattern flow rule creation in VF based on Parser Library feature. VF
parses the spec and mask input of raw pattern, and passes it to kernel
driver to create the flow rule. Current rte_flow raw API is utilized.

command example:
RSS hash for ipv4-src-dst:
flow create 0 ingress pattern raw pattern spec
00000000000000000000000008004500001400004000401000000000000000000000
pattern mask
0000000000000000000000000000000000000000000000000000ffffffffffffffff /
end actions rss queues end / end

[PATCH v6 1/3] common/iavf: support raw packet in protocol header

[Junfeng Guo]

The patch extends existing virtchnl_proto_hdrs structure to allow VF
to pass a pair of buffers as packet data and mask that describe
a match pattern of a filter rule. Then the kernel PF driver is requested
to parse the pair of buffer and figure out low level hardware metadata
(ptype, profile, field vector.. ) to program the expected FDIR or RSS
rules.

Also update the proto_hdrs template init to align the virtchnl changes.

[PATCH 1/2] net/iavf: enable Protocol Agnostic Flow Offloading FDIR

[Junfeng Guo]

This patch enabled Protocol Agnostic Flow (raw flow) Offloading Flow
Director (FDIR) in AVF, based on the Parser Library feature and the
existing rte_flow `raw` API.

The input spec and mask of raw pattern are first parsed via the
Parser Library, and then passed to the kernel driver to create the
flow rule.

Similar as PF FDIR, each raw flow requires:
1. A byte string of raw target packet bits.
2. A byte string contains mask of target packet.

Here is an example:
FDIR matching ipv4 dst addr with 1.2.3.4 and redirect to queue 3:

flow create 0 ingress pattern raw \
pattern spec \
00000000000000000000000008004500001400004000401000000000000001020304 \
pattern mask \
000000000000000000000000000000000000000000000000000000000000ffffffff \
/ end actions queue index 3 / mark id 3 / end

Note that mask of some key bits (e.g., 0x0800 to indicate ipv4 proto)
is optional in our cases. To avoid redundancy, we just omit the mask
of 0x0800 (with 0xFFFF) in the mask byte string example. The prefix
'0x' for the spec and mask byte (hex) strings are also omitted here.

From: Ting Xu <ting.xu@intel.com>

Enable Protocol Agnostic Flow Offloading for RSS hash in VF. It supports
raw pattern flow rule creation in VF based on Parser Library feature. VF
parses the spec and mask input of raw pattern, and passes it to kernel
driver to create the flow rule. Current rte_flow raw API is utilized.

command example:
RSS hash for ipv4-src-dst:
flow create 0 ingress pattern raw pattern spec
00000000000000000000000008004500001400004000401000000000000000000000
pattern mask
0000000000000000000000000000000000000000000000000000ffffffffffffffff /
end actions rss queues end / end

You should not have merged this, it is triggering an error
with devtools/check-doc-vs-code.sh

rte_flow doc out of sync for iavf
        item raw

Once again, I will fix it while pulling the tree.
There are a lot of mistakes in this tree,
I hope you understand why I don't have time to pull it
as frequently as you would like.

my bad, I was reminded by Ferruh previously.
I should add check-doc-vs-code.sh into my routine operation.

Understand your concern, I can't guarantee there will be no mistake, but I will try to avoid the same mistake happen again.
