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.

This patch adds support for (imperfect) filtering of
VLAN tag ids using a 16-bit filter hash table. When
VLANs are added, a 4-bit hash is calculated with the
result indicating the bit in the hash table to set.
This table is used by the hardware to drop packets with
a VLAN id that does not hash to a set bit in the table.

MAX_DMA_CHANNELS is defined in asm/scatterlist.h of the powerpc
architecture. Rename this #define in xgbe.h to avoid the
redefined warning issued during compilation.
