[dpdk-dev] net/mlx5: flow counters support for Linux-rdma v19

[Slava Ovsiienko]

Mellanox mlx5 PMD supports Flow counters via Verbs library.
The current implementation is based on the Mellanox proprietary
Verbs library included in MLNX OFED packages. The Flow counter
support is recently added into linux-rdma release (v19),
so the mlx5 PMD update is needed to provide Counter feature
on the base of linux-rdma.

mlx5 PMD can be compiled with MLNX OFED or linux-rdma v19+
and provide flow counters for both.
