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. + +Signed-off-by: Björn Smedman +Reviewed-by: Johannes Berg +Cc: stable@kernel.org +Signed-off-by: John W.
