Merge branch 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux

mlx5-next shared branch with rdma subtree to avoid mlx5 rdma v.s. netdev
conflicts.

Highlights:
1) Lag refactroing and flow counter affinity bits.
2) mlx5 core cleanups

By Roi Dayan (2) and others
* 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux:
  net/mlx5: Fold the modify lag code into function
  net/mlx5: Add lag affinity info to log
  net/mlx5: Split the activate lag function into two routines
  net/mlx5: E-Switch, Introduce flow counter affinity
  IB/mlx5: Unify e-switch representors load approach between uplink and VFs
  net/mlx5: Use lowercase 'X' for hex values
  net/mlx5: Remove duplicated include from eswitch.c
