[dpdk-dev] [PATCH v1 00/29] net/mlx4: restore PMD functionality

[Adrien Mazarguil <adrien.mazarguil@6wind.com>]

This series restores all the control path functionality removed in prior
series "net/mlx4: trim and refactor entire PMD", including:

- Promiscuous mode.
- All multicast mode.
- MAC address configuration.
- Support for multiple simultaneous MAC addresses.
- Reception of broadcast and user-defined multicast traffic.
- VLAN filters.
- RSS.

This rework also results in the following enhancements:

- Support for multiple flow rule priorities (up to 4096).
- Much more comprehensive error messages when failing to create or apply
  flow rules.
- Flow rules with the RSS action targeting disparate queues can now overlap
  (as long as they take HW limitations into account).
- RSS contexts can be created/destroyed on demand (they were previously
  fixed once and for all after applying the first flow rule).
- RSS hash key can be configured per context.
- Rx objects have a smaller memory footprint.

Note that it should be applied directly before the following series:

 "new mlx4 datapath bypassing ibverbs"

For which a new version based on top of this one will be submitted soon.
