[PATCH 23/31] FreeBSD OFED support for DPDK MLX5 PMD
a) Expose tag matching capabilities and show them in ibv_devinfo.
b) verbs: Introduce tag matching SRQ
Introducing tag matching SRQ (TM-SRQ), which retains basic semantic of
regular SRQ, reports completions to own CQ, and has additional tag
based message receiving mechanism.
Detailed description for the TM-SRQ usage was added into
Documentation/tag_matching.md
c) mlx5: Add support to tag matching SRQ type
Create command QP for a tag-matching SRQ. Command QP used for
inserting/removing entries from the tag matching list. This command QP
is hidden from the users in the mlx5_srq structure.
New verb ibv_post_srq_ops() will be added in next patch to use it.
