If ixgbevf is loaded while the corresponding PF interface is down and the driver assigns a random MAC address, that address can be overwritten with the value of hw->mac.perm_addr, which would be 0 at that point.

To avoid this case we init hw->mac.perm_addr to the randomly generated address and do not set it unless we receive ACK from ixgbe.
