From 8a690674e0601efbe9a7b16a5826fc522645cca3 Mon Sep 17 00:00:00 2001 From: Ben Greear Date: Tue, 17 Apr 2012 10:54:16 -0700 Subject: mac80211: Support on-channel scan option. This based on an idea posted by Stanislaw Gruszka, though I accept full blame for the implementation! This has been tested with ath9k. The idea is to let users scan on the current operating channel without interrupting normal traffic more than absolutely necessary (changing power level might reset some hardware, for instance).
