====================
Mellanox mlx5e fixes for 4.11-rc1

This series includes some important bug fixes for mlx5e driver.

Three misc fixes:
From Mohamad, compilation fix on s390 system
From Me, A fix for driver unload when switchdev mode is on.
From Tariq, HW LRO frag size optimization for when build_skb is not used
(striding RQ mode).

Three CQE compression related fixes:
Two fixes from Tariq and I, to correctly setup CQE compression
parameters on driver load and on arbitrary user modifications.
Last patch, fixes a very critical issue that was originally reported
by Tom, where the driver reported csum errors or even page ref issues
for when cqe compression is enabled and rapidly active.

For your convenience this series was generated on top of net-next branch:
