801c62d945 amd-xgbe: Add support for VLAN filtering
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.

6e5eed042f amd-xgbe: VLAN Tx tag insertion fix
The MAC_VLAN_Incl register (0x0060) must be set to indicate
that the VLAN tag to be inserted comes from a Tx context
descriptor and not the MAC_VLAN_Incl register.  Also, even
though it is the default, explicitly set the type of tag to
be inserted as a CTAG.
