Can you elaborate some on why you think umlme is required for these
(or other) functions?  It isn't obvious to me that all of these MLME
functions are so complex as to require userland implementations.

Forgive my skepticisim, but in the past umlme has been used as a
religious hammer.   I don't want to keep apparently working/workable
code out of the kernel just because someone thinks currently
non-existant umlme code would be a better solution.

Lacking a mature umlme implementation in-hand, I'm not prepared
to accept a preemptive veto on kmlme extensions without seeing the
code first.
