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



Misc updates from mlx5-next branch.

1) Eli improves the handling of the support for QoS element type
2) Gavi refactors and prepares mlx5 flow counters for bulk allocation
support
3) Parav, refactors and improves E-Switch load/unload flows
4) Saeed, two misc cleanups
