From f9616e0f8828fba6c06d1feff1c26eaf049b1e8a Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Fri, 13 Apr 2012 16:38:40 +0530 Subject: 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 Signed-off-by: John W.
