Merge branch 'mlx5-next' 

Saeed Mahameed says:

====================
Mellanox 100G mlx5 SRIOV switchdev update

This series from Roi and Or further enhances the new SRIOV switchdev mode.

Roi's patches deal with allowing users to configure though devlink
the level of inline headers that the VF should be setting in order for
the eswitch HW to do proper matching. We also enforce that the matching
required for offloaded TC rules is aligned with that level on the PF driver.

Or's patches deals with allowing the user to control on the VF operational
link state through admin directives on the mlx5 VF rep link. Also in this series
is implementation of HW and SW counters for the mlx5 VF rep which is aligned
with the design set by commit a5ea31f573 'Merge branch net-offloaded-stats'.

v1 --> v2:
* constified the net-device param of get offloaded stats ndo in mlxsw
  (pointed by 0-day screaming on us...)
* added Or's Review-by tags for Roi's patches

This series was generated against commit
e796f49d82 ("net: ieee802154: constify ieee802154_ops structures")
