Mellanox ConnetX devices supports packet matching, packet modification and
redirection. These functionalities are also referred to as flow-steering.
To configure a steering rule, the rule is written to the device owned
memory, this memory is accessed and cached by the device when processing
a packet.

The highlight of this patchset is supporting HW Steering (HWS) which
is the new technology supported in new ConnectX devices, HWS allows
configuring steering rules directly to the HW using special HW queues
with minimal CPU effort.

This patchset is the internal low layer implementation for HWS used by
the mlx5 PMD. The mlx5dr (direct rule) is layer that bridges between the
PMD and the HW by configuring the HW offloads based on the PMD logic

This is the initial draft to present the code to the community and it will
be reworked.

Alex Vesker (13):
  net/mlx5: Add additional glue functions for HWS
  net/mlx5: Remove stub HWS support
  net/mlx5/hws: Add HWS command layer
  net/mlx5/hws: Add HWS pool and buddy
  net/mlx5/hws: Add HWS send layer
  net/mlx5/hws: Add HWS definer layer
  net/mlx5/hws: Add HWS context object
  net/mlx5/hws: Add HWS table object
  net/mlx5/hws: Add HWS matcher object
  net/mlx5/hws: Add HWS rule object
  net/mlx5/hws: Add HWS action object
  net/mlx5/hws: Add HWS debug layer
  net/mlx5/hws: Enable HWS

Bing Zhao (2):
  common/mlx5: query set capability of registers
  net/mlx5: provide the available tag registers

Dariusz Sosnowski (1):
