C7v2 here. 21.02
eth0: 73
eth1: 72 (br-lan)
wlan0: 71 (11n+ac, 5GHz)
wlan1: 72 (11bgn, 2.4GHz)
Works fine as is.

Hi,
I'm using two tp-link routers. Both are using the same mac address for
one eth and one wlan interface:
archer c7-v2:
uboot 60:xx:xx:xx:xx:E6
eth0 60:xx:xx:xx:xx:E7
eth1 60:xx:xx:xx:xx:E6
wlan0 60:xx:xx:xx:xx:E4 5G
wlan1 60:xx:xx:xx:xx:E6 2.4G
wdr3600:
uboot C0:xx:xx:xx:xx:60
eth0 C0:xx:xx:xx:xx:60
wlan0 C0:xx:xx:xx:xx:5F 2.4G
wlan1 C0:xx:xx:xx:xx:60 5G
It looks like if an address decrement is missing for one wlan interface.
I don't know if this can trigger a problem.
With a small patch, I did fix it for both of my routers:

Now I get:
archer c7-v2:
eth0 60:xx:xx:xx:xx:E7
eth1 60:xx:xx:xx:xx:E6
wlan0 60:xx:xx:xx:xx:E4 5G

eth0 C0:xx:xx:xx:xx:60
wlan0 C0:xx:xx:xx:xx:5F 2.4G
wlan1 C0:xx:xx:xx:xx:5E 5G
I don't know, if exist some rule whether decrement by -1/-2 shall refer
to the interface number or to the frequency.
