mac80211: sequence number micro-optimisation
There's no need to mask the variable with 0xFFF0 since we ever only use it as a u16 and the lowest four bits can't ever be non-zero. The compiler cannot infer the latter, and therefore has to emit code to do the masking. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
