It's a matter of a few minutes to add the code, and a few hours to test
it.  The difficult part is coming up with good interfaces.  The kernel
module API, kernel locking, and the syscall interfaces must all be
designed and documented.

If you need a one-off static setting, you can do it by passing the
desired VLAN with a module option, and just write that value directly to
the VLT register.  Doing it this way avoids all of the interface and
locking issues.
