   4 Subject: [PATCH] mac80211: fix for incorrect sequence number on hostapd injected frames

   9 When hostapd injects a frame, e.g. an authentication or association
  10 response, mac80211 looks for a suitable access point virtual interface
  11 to associate the frame with based on its source address. This makes it
  12 possible e.g. to correctly assign sequence numbers to the frames.
  13
  14 A small typo in the ethernet address comparison statement caused a
  15 failure to find a suitable ap interface. Sequence numbers on such
  16 frames where therefore left unassigned causing some clients
  17 (especially windows-based 11b/g clients) to reject them and fail to
  18 authenticate or associate with the access point. This patch fixes the
  19 typo in the address comparison statement.
