From 20eb7ea93f7ffaaa24b19b8bfc411b1f7605759f Mon Sep 17 00:00:00 2001 From: David Spinadel Date: Tue, 3 May 2016 16:05:02 +0300 Subject: [PATCH] mac80211: remove disconnected APs from BSS table In some cases, after a sudden AP disappearing and reconnection to another AP in the same ESS, user space gets the old AP in scan results (cached). User space may decide to roam to that old AP which will cause a disconnection and longer recovery. Remove APs that are probably out of range from BSS table.
