As far as I can tell your card doesn't accelerate VLANs in hardware
at all, is this true?

I think it's very cumbersome and it doesn't make sense for every
driver in your situation to add this same sequence of software calls.

Some generic facility and interfaces should be created so that the
code doing this software VLAN acceleration is consolidated into
one place and any driver can follow a simple to use API in order
to make use of it.
