Hi,

I haven't checked the vendor FW, I only have OpenWrt on it and would
have to flash somehow back.

The LAN MAC in OpenWrt is: 40:31:3c:02:8f:b8
The WAN MAC in OpenWrt is: 40:31:3c:02:8f:b7

The label says: 40:31:3C:02:8F:B8

In the bootlog of the vendor FW I see this:
[    7.520000] set LAN/WAN LWLLL
[    7.530000] GMAC1_MAC_ADRH -- : 0x00004031
[    7.530000] GMAC1_MAC_ADRL -- : 0x3c028fb7
[    7.530000] GDMA2_MAC_ADRH -- : 0x00004031
[    7.540000] GDMA2_MAC_ADRL -- : 0x3c028fb8
[    7.540000] eth1: ===> VirtualIF_open
