No. Link layer stuff is all handled in either the device driver or the 802.11 common layer (on linux, this would be in mac80211)

In general the drivers ought to be enforcing state machine to prevent totally bogus state transitions. You're likely to find trying to mandate things like packet seqnos will end up breaking things.
