X-Git-Tag: v21.02.0-rc1~4393
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=e00396d58420de96b660cfb918a0255f145c965f

ramips: add label MAC address for TP-Link Archer C20i

Current OpenWrt MAC setup:
eth0             &rom 0xf100    :48
eth0.2           eth0+1         :49
wlan0 (5 GHz)    &radio 0x8004  different OUI
wlan1 (2.4 GHz)  &radio 0x4     same OUI as wlan0

Label MAC address corresponds to eth0 (&ethernet).

No additional addresses found in hexdump of rom/radio.
