amd-xgbe: Change destination address filtering support
Currently the driver makes use of the additional mac address
registers in the hardware to provide perfect filtering. The
hardware can also have a set of hash table registers that can
be used for imperfect filtering. By using imperfect filtering
the additional mac address registers can be used for layer 2
filtering support. Use the hash table registers if the device
has them.
