Yes, I just merged in support for this (dynamic VLANs) into hostapd.
RADIUS Access-Accept is used select VLAN is being used and the STA is
bound at that point to another virtual interface, if needed.

That would be fine, too, but maybe not necessary.

Well, that would probably be correct for most (all?) cases, but then
again, I would probably not bother with this level of validation in
kernel. Whatever is taking care of binding the STA in user space (e.g.,
hostapd) can do the validation.
