[v6,00/18] net/mlx5: Add HW steering low level support

  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

v2:
Fix check patch and cosmetic changes

v3:
-Fix unsupported items
-Fix compilation with mlx5dv dependency

v4:
-Fix compile on Windows

v5:
-Fix compile on old rdma-core or no rdma core

v6:
-Fix meson style and improve configure
-Checkpatch and compilation fixes
-Fix action number issue
