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? -- Rafał -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
