From b2c76bbe005cd23dfd80fe2140bd18daf4d3b16a Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Thu, 21 Jul 2011 09:40:00 +0300 Subject: ath6kl: don't force foreground scan when connected In my setup data transfer stalls when there's data transmission during scan. After some testing I found out that using background scan when connected to makes the problem go away. This is more like a workaround than a proper fix, but as the stall is so severe the workaround is justified. With a dual band card this increases scan time when connected from 1.9s to 4.4s. When not connected the scan time is not affected and is the same 1.9s.
