Since the PHY is powered up at reset this has not been a problem. However, when the kernel is restarted with kexec the PHY will likely be powered down when the kernel starts so it will not be detected and the Ethernet link will not be established. This commit explicitly powers up the internal PHY when the GENET driver is probed to correct this behavior.

The issue appears to be that one copy was delivered based on the source MAC address and then the second copy was being delivered based on the destination MAC address. To fix it I am just treating a unicast address match as though it is not a match since source based macvlan isn't supposed to be matching based on the destination MAC anyway.
