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 written for that dimensions.

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

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

ACK
