The mac80211 decides when to switch back to oper channel based on tx queue, bad latency and listen time. As the station does not have tx traffic, the bgscan can easily affect downlink throughput. By reducing the listen time, it helps the associated AP to retain the downstream rate. Cc: Paul Stewart Tested-by: Gary Morain Signed-off-by: Rajkumar Manoharan Signed-off-by: John W.
