Monitoring mode gets frames from more than one channel!

I think 5 channel separation is enough not to allow packet
decodification on physical layer, even though it is not enough to
avoid interferences. I suspect it is a firmware issue. The card keeps
collecting statistics from other channels in orther to perform future
handovers.

Setting mode 2 roaming (iwpriv wlan0 host_roaming 2) still produces
the same behaviour?
