From: Ilan Peer <[email protected]> To support Pre Association Security Negotiation (PASN) while already associated to one AP, allow user space to register to Rx authentication frames, so that the user space logic would be able to receive/handle authentication frames from a different AP as part of PASN.
Note that it is expected that user space would intelligently register for Rx authentication frames, i.e., only when PASN is used and configure a match filter only for PASN authentication algorithm, as otherwise the MLME functionality of mac80211 would be broken.
