I'm told Network Manager scans every 60 seconds. When TX'ing or RX'ing
a lot of data you will see a big dip in throughput and sometimes it
may cause issues with some connections. Jouni pointed out a possible
nice option here: split the scans per channel through time. Now with
nl80211 this is possible but right now Network Manager uses wext
through wpa_supplicant in many distributions and this won't change for
a bit (maybe by the next major distribution releases?). Since we're
stuck with wext for the current distribution releases I'd like to hear
feedback on a possible nice solution. Should we simply cancel scan?
