Merge branch 'mlx5-fixes'

Saeed Mahameed says:

====================
Mellanox 100G mlx5 fixes 2016-08-16

This series includes some bug fixes for mlx5e driver.

From Saeed and Tariq, Optimize MTU change to not reset when it is not required.

From Paul, Command interface message length check to speedup firmware
command preparation.

From Mohamad, Save pci state when pci error is detected.

From Amir, Flow counters "lastuse" update fix.

From Hadar, Use correct flow dissector key on flower offloading.
Plus a small optimization for switchdev hardware id query.

From Or, three patches to address some E-Switch offloads issues.

For -stable of 4.6.y and 4.7.y:
    net/mlx5e: Use correct flow dissector key on flower offloading
    net/mlx5: Fix pci error recovery flow
    net/mlx5: Added missing check of msg length in verifying its signature
====================
