Merge branch 'mlx4-next'

Or Gerlitz says:

====================
Mellanox mlx4 driver updates

The main feature added by this series are Ido's changes to support
Granular QoS for VFs, where for the time being only max rate is supported.

Muhammad added support for setting rx-fcs and rx-all through ethtool,
and Ido did the interface identify work.

Last, add Ido as a maintainer for the mlx4 Ethernet driver!

Some of next week is the Passover holiday here and I will be
mostly OOO. If needed (...) Ido or Amir will send V1 and such.

Rebased against net-next commit 033f46b3 "crypto: algif -
explicitly mark end of data".
====================
