====================
Mellanox driver update, Oct 14 2015

This series contains two more patches from Eli, patch from Majd
to support PCI error handlers and a fix from Jack to mlx4 VFs
when probed without a provisioned mac address.

The patch set applied on top of net-next commit bbb300e "Merge branch 'bridge-vlan'"

changes from V0:
  - made the health flag int --> bool to address comment from Dave on patch #1
  - fixed sparse warning noted by the 0-day build tests in patch #2
