Subject: net/mlx5: add flow action functions to glue
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=56ef2c58159696ce37e4eedf769296a79e6a76a7;p=dpdk.git

net/mlx5: add flow action functions to glue

This patch adds glue functions for operations:
- Create packet reformat (encap/decap) flow action.
- Destroy flow action.

The new operations depend on HAVE_IBV_FLOW_DV_SUPPORT.
