cfg80211: increse bss expire time
The background scan completion takes more time when the station is having heavy uplink traffic. The scan state machine decides to fall back to home channel on every off-channel visit when there are pending frames in tx queue. bgscan completion took ~30sec on dual band US regulatory card. scan period = (20 active channels * probe timeout) + (12 passive channels * passive probe timeout) + (32 * timeout on home channel) + (32 * flush timeout) Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.
