[PATCH 18/50] AP: Match Rx frames against MLD address

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ilan Peer <ilan.peer@xxxxxxxxx>

Once a station is added to the underlying driver, the driver
is expected to do address translation and use MLD addresses.
Thus, when handling a Rx management frame, match it against
the MLD address.
