Subject: Aw: [PATCH net v3 4/5] net: ethernet: mtk_eth_soc: drop generic
 vlan rx offload, only use DSA untagging

Hi,

v2 or v3 seems to break vlan on mt7986 over eth0 (mt7531 switch). v1 was working on next from end of November. But my rebased tree with v1 on 6.2-rc1 has same issue, so something after next 2711 was added which break vlan over mt7531.

Directly over eth1 it works (was not working before).

if i made no mistake there is still something wrong.

btw. mt7622/r64 can also use second gmac (over vlan aware bridge with aux-port of switch to wan-port) it is only not default in mainline. But maybe this should not be used as decision for dropping "dsa-tag" (wrongly vlan-tag).

regards Frank
