====================
ethtool, net/mlx4_en: RSS hash function selection

This patchset by Eyal adds support in set/get of RSS hash function. Current
supported functions are Toeplitz and XOR. The API is design to enable adding
new hash functions without breaking backward compatibility.
Userspace patch will be sent after API is available in kernel.

The patchset was applied and tested over commit e35cfce ("netpoll: delete
defconfig references to obsolete NETPOLL_TRAP")
