This will get a new PCI ID for the mlx4 driver, which also requires
handling one new firmware status code. The chance of regressions
should be near-nil, since existing devices won't hit any of the new
code (and the worst case seems to be printing an incorrect error
message anyway).

mlx4_core: Handle multi-physical function devices
mlx4_core: Add new ConnectX EN PCI ID 0x6764
