42there are several "locks" in mlme_priv,
43since mlme_priv is a shared resource between many threads,
44like ISR/Call-Back functions, the OID handlers, and even timer functions.
45Each _queue has its own locks, already.
46Other items are protected by mlme_priv.lock.
47To avoid possible dead lock, any thread trying to modifiying mlme_priv
48SHALL not lock up more than one locks at a time!
