This breaks nothing. I think if you set your BSSID manually, you really=
 don't want that the driver changed it back. If you want this behavior,=
 you don't set it.
Handle BSSID splits in a mile width city mesh network with 500 or more =
nodes is impossible in a other way, I think. The standard was never wri=
tten for that dimensions.

Besides it fixes a bug that driver want to try to merge with the same B=
SSID, which is unnecessary and causes problems.

We need it much here in the "Freifunk" mesh network of Berlin.
