Add me in to be the 3rd report...
RK3568 GMAC0 (eth1) to MT7531BE (CPU port)
Current workaround for me is ethtool -K eth1 rx off tx off

Question on the patch to be built: how would I know if my setup could take advantage of the HW checksum offload? RK3658’s eth0 on stmmac is doing fine, and eth0 is not on a DSA switch. Does this mean eth1 should be able to do hw checksum offload once the stmmac driver is fixed?
