[dpdk-dev] [PATCH v2 00/16] Enhance mlx5 with Mellanox OFED 3.1

[Adrien Mazarguil]

Mellanox OFED 3.1 [1] comes with improved APIs that Mellanox ConnectX-4
(mlx5) adapters can take advantage of, such as:

- Separate post and doorbell operations on all queues.
- Lightweight RX queues called Work Queues (WQs).
- Low-level RSS indirection table and hash key configuration.

This patchset enhances mlx5 with all of these for better performance and
flexibility. Documentation is updated accordingly.

Changes in v2:
- Fixed compilation errors due to a missing libibverbs callback in the first
  two commits.
- Improved clean up in device stop function.
- Added flows clean up when going promiscuous to save HW resources.
- Removed VF check in promiscuous mode.
- Added RSS support for IPv6 flows.
- Renamed flow specification generator function.
- Modified allmulticast code to use enhanced flow specifications.
- Remaining changes are caused by rebase on v2 of the initial patchset
  ("Mellanox ConnectX-4 PMD (mlx5)").
