The problem is reproducible fine: I'm running in a loop SCP traffic up
and down to my ISP host; when the background scan every five minutes
takes place the traffic gets STALLED and IP comes not to work again:

from now the interface does not let pass frames anymore

I tested the same in an older 10-ALPHA4 laptop (running r255948 from
October 2013) with the same physical WLAN card; there is no problem with
the bg scans every 5 minutes, it just goes ahead after any scan; this is
an issue in head.
