I didn't know that. In fact, from my understanding of the current
source, if you fix the BSSID, you won't merge, period. And even if you
don't fix the BSSID, if you found a BSS with the same BSSID but a
different channel, you still won't merge.

And now, if you are alone and you fixed your channel, you won't try to
merge with other BSS in the same channel.

If you believe that the condition should be "fixed_bssid &&
fixed_channel", i can send another patch.
