From 34bcf71502413f8903ade93746f2d0f04b937a78 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Tue, 11 Dec 2012 10:48:23 +0100 Subject: mac80211: fix ibss scanning Do not scan on no-IBSS and disabled channels in IBSS mode. Doing this can trigger Microcode errors on iwlwifi and iwlegacy drivers. Also rename ieee80211_request_internal_scan() function since it is only used in IBSS mode and simplify calling it from ieee80211_sta_find_ibss().
