I would notify mac only if driver cannot deal with reset and also
mac80211 configuration have to be reapplied such as start association
process again in STA mode.   It would be probably security problem if
we put just station into associated mode without proper association
process.
If in AP mode  stations have only soft state that it would be probably
not necessary to reset station table.
