Unless the 802.1q code is built as a module. It looks to me like if you
unregistered the virtual interface and unload the 802.1q module, if another
tagged packet is received tg3 will still call vlan_hwaccel_rx and deref
tp->vlgrp which now points to who knows what.

Any time VLAN groups exist, the VLAN module should not be unloadable.

This is a hokey area of how the VLAN layer works and I intend
to fix it.
