Browse source 
Leon Romanovsky says:

====================
This series from Alex extends software steering interface to support
devices with extra capability "sw_owner_2" which will replace existing
"sw_owner".
====================

Based on the mlx5-next branch at
     git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux
due to dependencies.

* branch 'mlx5_sw_owner_v2:
  RDMA/mlx5: Expose TIR and QP ICM address for sw_owner_v2 devices
  RDMA/mlx5: Allow DM allocation for sw_owner_v2 enabled devices
  RDMA/mlx5: Add sw_owner_v2 bit capability
