[dpdk-dev] [PATCH] ethdev: add HIGIG2 key field to flow API

[kirankumark]

From: Kiran Kumar K <kirankumark@marvell.com>

Add new rte_flow_item_higig2_hdr in order to match higig2 header.
It is a layer 2.5 protocol and used in broadcom switches.
Header format is based on the following document.

As far as I remember support in testpmd is a must requirement
to add new RTE flow API feature.

Right now there is one empty line between items and two between
the last item and actions. It should be preserved.

Usage of bit fields in network headers require
big/little endian handling. See lib/librte_net/rte_gre.h
Also other network protocol headers are defined in
lib/librte_net.

It would be useful to see default mask choice motivation.

It would be useful to see default mask choice motivation.

[dpdk-dev] [PATCH] ethdev: add HIGIG2 key field to flow API

[kirankumark]

From: Kiran Kumar K <kirankumark@marvell.com>

Add new rte_flow_item_higig2_hdr in order to match higig2 header.
It is a layer 2.5 protocol and used in broadcom switches.
Header format is based on the following document.

[dpdk-dev] [PATCH v3] ethdev: add HIGIG2 key field to flow API

[kirankumark]

From: Kiran Kumar K <kirankumark@marvell.com>

Add new rte_flow_item_higig2_hdr in order to match higig2 header.
It is a layer 2.5 protocol and used in broadcom switches.
Header format is based on the following document.

V3 Changes:
* Fixed Copyright header
* Fixed version info in the subject

V2 Changes:
* Added support in testpmd to parse the higig2 item
* Moved the higig2 header to new file
* Added indentation in doc

Will fix in V4.

[dpdk-dev] [PATCH v4] ethdev: add HIGIG2 key field to flow API

[kirankumark]

From: Kiran Kumar K <kirankumark@marvell.com>

Add new rte_flow_item_higig2_hdr in order to match higig2 header.
It is a layer 2.5 protocol and used in broadcom switches.
Header format is based on the following document.
http://read.pudn.com/downloads558/doc/comm/2301468/HiGig_protocol.pdf

Signed-off-by: Kiran Kumar K <kirankumark@marvell.com>
---
V4 Changes:
* Removed packed attribute

V3 Changes:
* Fixed Copyright header
* Fixed version info in the subject

V2 Changes:
* Added support in testpmd to parse the higig2 item
* Moved the higig2 header to new file
* Added indentation in doc

It is inconsistent vs header name. Should be _RTE_HIGIG_H_.

[dpdk-dev] [PATCH v5] ethdev: add HIGIG2 key field to flow API

[kirankumark]

From: Kiran Kumar K <kirankumark@marvell.com>

Add new rte_flow_item_higig2_hdr in order to match higig2 header.
It is a layer 2.5 protocol and used in Broadcom switches.
Header format is based on the following document.
http://read.pudn.com/downloads558/doc/comm/2301468/HiGig_protocol.pdf

+1 to have protocol documentation, but what is 'pudn.com'? Is it kind of
download site? Isn't there any official web site for the protocol?

'lib/librte_net/' maintainer is Olivier, so by default new file maintainer will
be Olivier, it is good to get his ack to confirm this before merging patch.

Also can you please update "doc/api/doxy-api-index.md" to add new 'rte_higig.h'
file so that it can be part of our API documentation.

btw, 'rte_gre.h' & 'rte_mpls.h' are seems missing in API documentation, another
patch to add them would be nice if possible.

rte_higig.h is a generic file, it should not have any reference to rte_flow

Doxygen comment could be "higig2 frc header"

move this to rte_flow.h and add the following rte_flow.h so that
rte_higig.h is standalone it can be used for other purposes other than
rte_flow.

/**
 * RTE_FLOW_ITEM_TYPE_HIGIG2.
 *
 * Matches higig2 header.
 */
struct rte_flow_item_higig2_hdr {
        struct rte_higig2_hdr hdr; /**< Higig2 header definition. */
};

See rte_flow_item_tcp and rte_tcp_hdr as reference usage.

[dpdk-dev] [PATCH v8] ethdev: add HIGIG2 key field to flow API

[kirankumark]

From: Kiran Kumar K <kirankumark@marvell.com>

Add new rte_flow_item_higig2_hdr in order to match higig2 header.
It is a layer 2.5 protocol and used in Broadcom switches.
Header format is based on the following document.

[dpdk-dev] [PATCH v9] ethdev: add HIGIG2 key field to flow API

[kirankumark]

From: Kiran Kumar K <kirankumark@marvell.com>

Add new rte_flow_item_higig2_hdr in order to match higig2 header.
It is a layer 2.5 protocol and used in Broadcom switches.
Header format is based on the following document.

I don't know this protocol, but the output of pahole for this struct
(little endian version) is:

struct rte_higig2_ppt_type1 {
	uint16_t                   classification;       /*     0     2 */
	uint16_t                   resv;                 /*     2     2 */
	uint16_t                   vid;                  /*     4     2 */

	/* Bitfield combined with previous fields */

	uint32_t                   opcode:3;             /*     4:13  4 */
	uint32_t                   resv1:2;              /*     4:11  4 */
	uint32_t                   src_t:1;              /*     4:10  4 */
	uint32_t                   pfm:2;                /*     4: 8  4 */
	uint32_t                   resv2:5;              /*     4: 3  4 */
	uint32_t                   hdr_ext_len:3;        /*     4: 0  4 */

	/* size: 8, cachelines: 1, members: 9 */
	/* bit_padding: 16 bits */
	/* last cacheline: 8 bytes */
};

There is a 16 bits padding at the end, is it expected?

[dpdk-dev] [PATCH v10] ethdev: add HIGIG2 key field to flow API

[kirankumark]

From: Kiran Kumar K <kirankumark@marvell.com>

Add new rte_flow_item_higig2_hdr in order to match higig2 header.
It is a layer 2.5 protocol and used in Broadcom switches.
Header format is based on the following document.
http://read.pudn.com/downloads558/doc/comm/2301468/HiGig_protocol.pdf

and this is with gcc 4.8.5

From https://stackoverflow.com/questions/10906238/warning-when-using-bitfield-with-unsigned-char
it seems that it is allowed in c99, so I guess it's a gcc 4.8 bug.

Adding __extension__ above the struct solves the warnings, I suggest to
add it.

I have already added it. RTE_STD_C11 , this is a macro for __extension__.

#if !defined(__STDC_VERSION__) || __STDC_VERSION__ < 201112L

The __extension__ is only added if compiled for < c11.
But there is apparently a problem with gcc-4.8: even in c11, it does
not support bitfields on u16. See: https://godbolt.org/z/hRIbgg

On gcc-4.9, the problem disappeared: https://godbolt.org/z/kkzz9v

So as a workaround, using __extension__ should work, probably with a short
explanation.

Thanks Olivier, this was also our finding with Raslan and he sent the fix already.
https://patches.dpdk.org/patch/61748/

Also it looks like gcc4.8 thinks this is not c11 standard but extension only for
uint16_t type, structs with uint32_t bit-fieds works as expected.

Sorry, my comment is a bit late, but I would prefer to see HIGIG earlier in this list.
You say it is a protocol at layer 2.5, so it should be listed probably close to ICMP.
What is your opinion?
