> the problem is checksum offloading on the gmac (soc-side)

I suggested it might be checksum problem because I'm also affected. In
my case, I have an mt7620a SoC connected to the rtl8367s switch. The
OS offloads checksum to HW but the mt7620a cannot calculate the
checksum with the (EtherType) Realtek CPU Tag in place. I'll try to
move the CPU tag to test if the mt7620a will then digest the frame
correctly.
