mlx5-updates-2017-06-16 

This series provide some updates and cleanups for mlx5 core and netdevice
 driver.
 
 From Eli Cohen, add a missing event string.
 From Or Gerlitz, some checkpatch cleanups.
 From Moni, Disalbe HW level LAG when SRIOV is enabled.
 From Tariq, A code reuse cleanup in aRFS flow.
 From Itay Aveksis, Typo fix.
 From Gal Pressman, ethtool statistics updates and "update stats" deferred work optimizations.
 From Majd Dibbiny, Fast unload support on kernel shutdown.
