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

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?
