Merge branch 'mellanox-next'

Amir Vadai says:

====================
Mellanox ethernet driver update Oct-27-2014

This patchset introduces some small bug fixes, support in get/set of
vlan offload and get/set/capabilities of the link.

First 7 patches by Saeed, add support in setting/getting link speed and getting
cable capabilities.
Next 2 patches also by Saeed, enable the user to turn rx/tx vlan offloading on
and off.
Jenni fixed a bug in error flow during device initalization.
Ido and Jack fixed some code duplication and errors discovered by static checker.
last patch by me is a fix to make ethtool report the actual rings used by
indirection QP.

Patches were applied and tested against commit 61ed53d ("Merge tag 'ntb-3.18'
of git://github.com/jonmason/ntb")
