I managed to find/guess what exactly BCM43602 firmware rejects. It
doesn't like 2 MAC addresses that differ by the locally administrated
bit only. In my case it was 00:23:6a:a3:7d:95 + 02:23:6a:a3:7d:95.

When I change MAC addresses to some other combination, e.g.:
00:23:6a:a3:7d:95 + 00:23:6a:a3:7d:96
02:23:6a:a3:7d:95 + 00:23:6a:a3:7d:96
it works correctly.

Any idea why Broadcom driver/firmware team decided to reject MAC
address that differ by locally administrated bit only from the already
used one? I don't think there is anything wrong with that in general.

Is there a chance to release fixed firmware?
