No, at least at the beginning, but I will try to make everything modular
so that they can be called from up()/open() at init time based on module
options or later from ioctl/ethtool/whatever. I couldn't find anything
that would suggest races/misbehaviour if these features are enabled while
the interface is UP/RUNNING.

Yep, I'll try to split it into 2 parts: one that does the VLAN part (which
doesn't really depend on MTU size) and one that allows variable MTU.
