The proprietary driver has tag stripping options, as well. I have never
used it, though.
I think the tg3 driver will receive without tag stripping if the
interface is configured with a vlan (and then pass to the VLAN
interface), but always strip otherwise. I haven't messed with it in a
long time, so I could be wrong.
