Ummm they look distinct to me, one starts 74 the other 76? – user1998586
Ah. O que me confundiu é que você tem que verificar a parte que eu esperava ser o OUI.
O Netgear OUI original parece ser 74:44:01 , como usado no meu WNDR3800. Isso é usado em wlan0 (2.4Ghz), wlan1 (5Ghz) e eth1 (WAN).
103: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
link/ether 74:44:01:86:42:d4 brd ff:ff:ff:ff:ff:ff
107: wlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
link/ether 74:44:01:86:42:d6 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP qlen 1000
link/ether 74:44:01:86:42:d5 brd ff:ff:ff:ff:ff:ff
As outras interfaces parecem usar diferentes OUIs que não são mostradas como sendo registradas. Mas isso ocorre porque o bit Universal / Local, 0x02, foi definido (significando atribuído localmente). Cada BSSID é distinto.

A sequência de endereços MAC gerados não está clara para mim. No entanto, parece se reproduzir se eu excluir a última rede e, em seguida, recriá-lo.
Eu não tenho certeza porque eth0 / br-lan recebeu o mesmo endereço MAC que wlan0-1, ou se isso poderia causar algum problema outro . br-lan não inclui wlan0-1; o único membro da ponte é eth0.1.
