101 there are several "locks" in mlme_priv,

104
105 Each struct __queue has its own locks, already.
106 Other items in mlme_priv are protected by mlme_priv.lock, while items in
107 xmit_priv are protected by xmit_priv.lock.

109 To avoid possible dead lock, any thread trying to modifiying mlme_priv
110 SHALL not lock up more than one locks at a time!

112 The only exception is that queue functions which take the __queue.lock
113 may be called with the xmit_priv.lock held. In this case the order
