Ok, fine, I just set up a monitor interface and I see beacons
(and probe responses) for my setup on that channel.

There was a bug in older kernels that wouldn't fully configure the
beacons until after a reset, which scanning happens to do.  It's
possible something similar is going on.

Also, scanning might open a previously passive channel because we might
get lucky and receive a beacon from another node on it.  The 'iw phy
phy0 info' can show this kind of thing.
