The UniFi 6 Lite has two MAC addresses for the 2.4 and 5GHz radio in it's EEPROM partition. On my unit these are F4 92 BF A0 BB 6F F6 92 BF A0 BB 6F The problem with these is that mac80211 increases the first octet by 2, which leads to conflicting MAC addresses between radios. Work around this problem for now by increasing the last octet by 1 on the 5 GHz radio. Ubiquiti increases the last octet by 2 for each subsequent VAP created per radio. Ideally we should do the same, however this functionality is currently lacking from mac80211. Signed-off-by: David Bauer <mail@david-bauer.net>
