Most ATH driver use same beacon check. It is worth to place it
to the main ATH lib.

Apart from the fact that the expression in the if guard is badly
indented, couldn't you just return the value of that expression and
remove the if at all?

Would a static inline be better? At least on ath9k I suspect the
compiler automatically inlines the static function, after your patch
there's an extra function call.

[ath9k-devel] [PATCH 2/5] ath9k: use ath_is_mybeacon

[Oleksij Rempel]

This patch will also change behavior of rx_beacons statistic.
Instead of collecting all received beacons, it will collect only
ours. This, IMO make more sense, since for troubleshooting we will
need to know count of our beacons, or both.
