Merge branch 'mlx4-misc-for-4.16'

====================
mlx4 misc for 4.16

This patchset contains misc cleanups and improvements
to the mlx4 Core and Eth drivers.

In patches 1 and 2 I reduce and reorder the branches in the RX csum flow.
In patch 3 I align the FMR unmapping flow with the device spec, to allow
  a remapping afterwards.
Patch 4 by Moni changes the default QoS settings so that a pause
  frame stops all traffic regardless of its prio.
