I meant the DSA master network device, but you answered that, it uses a
mt7260a SoC, but there is no Ethernet driver upstream for it yet?

git grep ralink,mt7620-gsw *
Documentation/devicetree/bindings/net/mediatek,mt7620-gsw.txt:
compatible = "ralink,mt7620-gsw";

Ah so you have a cascade of switches here, that could confuse your
Ethernet MAC. Do you have a knob to adjust where to calculate the
checksum from, say a L2 or L3 offset for instance?
