Basically it takes 15 seconds to complete.
Interleaved scan seems very slow and is IMO unusable on Android

I wasn't seeing this on Debian because wpa_supplicant on my test system
doesn't behave this way.
I wonder would we be better off trying to serialize txrx::*tx with the
old scan method ?
Accepted it would be a passive scan but sw_scan seems to be so very very
slow - we might be beter off.
