Set the BGE_RX_MTU register correctly so that we can receive slightly
larger than normal frames, to account for the case where a bge(4) NIC
is used with VLANs. Since we set the IFCAP_VLAN_MTU flag, we must allow
reception of frames up to 1522 bytes in size rather than 1518.
Note that it is possible to work around this bug by doing:
# ifconfig bge0 mtu 1504
prior to configuring any VLAN interfaces.
