RDMA/mlx5: Add modify_op_stat() support

Browse source

Add support for ib callback modify_op_stat() to add or remove an optional
counter. When adding, a steering flow table is created with a rule that
catches and counts all the matching packets. When removing, the table and
flow counter are destroyed.
