ath79: fix MAC address setup for TP-Link TL-WDR3600/TL-WDR4300
The current ethernet MAC address setup of TL-WDR4300 board is different
from the setup of stock firmware:
OpenWrt: lan = label_mac -2, wan = label_mac -2
stock: lan = label_mac, wan = label_mac +1
The full address assignment is as follows:
LAN label
WAN label + 1
5G label
2G label - 1
This patch changes all devices using TL-WDR4300 board:
TL-WDR3600 v1 (checked on device)
TL-WDR4300 v1 (checked on device)
TL-WDR4300 v1 (IL)
