mac80211: improve IBSS scanning
When IBSS is fixed to a frequency, it can still scan to try to find the right BSSID. This makes sense if the BSSID isn't also fixed, but it need not scan all channels -- just one is sufficient. Make it do that by moving the scan setup code to ieee80211_request_internal_scan() and include a channel variable setting. Note that this can be further improved to start the IBSS right away if both frequency and BSSID are fixed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
