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

…/git/mellanox/linux

This merge commit includes some misc shared code updates from mlx5-next branch needed
for net-next.

1) From Aya: Enable general events on all physical link types and
   restrict general event handling of subtype DELAY_DROP_TIMEOUT in mlx5 rdma
   driver to ethernet links only as it was intended.

2) From Eli: Introduce low level bits for prio tag mode

3) From Maor: Low level steering updates to support RDMA RX flow
   steering and enables RoCE loopback traffic when switchdev is enabled.

4) From Vu and Parav: Two small mlx5 core cleanups

5) From Yevgeny add HW definitions of geneve offloads
