[dpdk-dev] [RFC] net/mlx5: add modify-header support using Direct Verbs

[Dekel Peled]

Modify-header actions support is implemented in librte_ethdev, and in test-pmd application, based on [1].
These actions include setting of source/destination IP, MAC & TP, as well as TTL.
Currently MLX5 PMD supports modify-header actions using TCF (netlink) API only.

This RFC adds to MLX5 PMD the support of modify-header actions, using Direct Verbs API.
It includes:

  *   Glue APIs to relevant DV functions and types.
  *   Validate modify-header actions.
  *   Convert modify-header actions to DV format.

Comments are welcome.
