See my previous reply [1], this definition is not endian-safe due to the use
of bit-fields and should look more like the VXLAN item. Here is an untested
suggestion (not sure about all values):
struct rte_flow_item_nvgre {
/**
* Checksum (1b), undefined (1b), key bit (1b), sequence number (1b),
* reserved 0 (9b), version (3b).
*
* \c_k_s_rsvd0_ver must have value 0x2000 according to RFC 7637.
*/
uint16_t c_k_s_rsvd0_ver;
uint16_t proto; /**< Protocol type (0x6558). */
uint8_t vsid[3]; /**< Virtual subnet ID. */
uint8_t flow_id; /**< Flow ID. */
};
Like for E-Tag, applications are responsibile for breaking down and filling
individual fields properly.
