Having already done FDDI support (which requires LLC support), I can
flatly state that Terry overstates the problem.  The LLC support is
trivial and can be stolen directly from my FDDI support.

Source routing (which is in the MAC header and has nothing to do with
LLC) is the main problem.  It's messy but doable.
