make aireplay-ng try to set channel if interface is on wrong channel
|Reported by:||stsp||Owned by:|
Currently, aireplay-ng will complain if the channel of the
interface does not match the channel of the target network,
and then it will just give up.
This simple patch makes it try to set the interface's channel to
the target channel before giving up. Saves the user a bit
of manual configuration hassle.
