Subject: [PATCH] ath9k: fix tracking of enabled AP beacons
|
|
|
|
sc->nbcnvifs tracks assigned beacon slots, not enabled beacons.
|
|
Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool)
|
|
should be updated, or if beacons have been enabled already.
|
|
With the current code (depending on the order of calls), beacons often
|
|
do not get enabled in an AP+STA setup.
|
|
To fix tracking of enabled beacons, convert cur_conf->enable_beacon to a
|
|
bitmask of enabled beacon slots.
