As forum category changes its name and a first question came up (user cannot create new threads)…
just to collect information in a bpi-r3 thread (and not in r2 threads)
bpi-r3 is afaik a planned board based on mt7986 SOC and mt7531 switch.
Bpi and mtk are working on hw layout and basic software support (basic patches like clock,pinctrl for linux got recently posted).
@sinovoip can you post more information of it,how far is development process? Can you separat wan port to second gmac (not connect to switch) like r2pro,as dsa can handle only 1 cpu port. Configurate it as separate external interface makes it easier to configure and use the gmac
