19: ath01: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue master br0 state UNKNOWN mode DEFAULT group default link/ether 82:d2:94:ba:08:dc brd ff:ff:ff:ff:ff:ff (Backhaul 2.4GHz)

20: ath02: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue master br0 state UNKNOWN mode DEFAULT group default link/ether 86:d2:94:ba:08:dc brd ff:ff:ff:ff:ff:ff(Backhaul-ADD 2.4GHz)

21: ath1: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue master br0 state UNKNOWN mode DEFAULT group default link/ether 78:d2:94:ba:08:de brd ff:ff:ff:ff:ff:ff (Fronthaul 5GHz)

22: ath11: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue master br0 state UNKNOWN mode DEFAULT group default link/ether 7e:d2:94:ba:08:de brd ff:ff:ff:ff:ff:ff (Backhaul-ADD5GHz)

23: ath2: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue master br0 state UNKNOWN mode DEFAULT group default link/ether 78:d2:94:ba:08:df brd ff:ff:ff:ff:ff:ff (Backhaul 5GHz)

So the name of the radio channels according to the wifi scan in the picture in the previous post will be as follows:

ath0 (Fronthaul 2)

ath01 (Backhaul 2)

ath02 (Backhaul 4)

ath1 (Fronthaul 1)

ath11 (Backhaul 3)

ath2 (Backhaul 1)
