[v9] ethdev: add HIGIG2 key field to flow API
Checks
Commit Message
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?
