[47/99] mac80211: fix for incorrect sequence number on hostapd injected frames

2.6.31-stable review patch. If anyone has any objections, please let us know.

From: Björn Smedman <bjorn.smedman@xxxxxxxxxxx>

commit 9b1ce526eb917c8b5c8497c327768130ee683392 upstream.

When hostapd injects a frame, e.g. an authentication or association
response, mac80211 looks for a suitable access point virtual interface
to associate the frame with based on its source address. This makes it
possible e.g. to correctly assign sequence numbers to the frames.

A small typo in the ethernet address comparison statement caused a
failure to find a suitable ap interface. Sequence numbers on such
frames where therefore left unassigned causing some clients
(especially windows-based 11b/g clients) to reject them and fail to
authenticate or associate with the access point. This patch fixes the
typo in the address comparison statement.
