I recognize the ethtool stats as belonging to the DPAA1 Ethernet driver. And I see that the Marvell 6390 has undocumented EDSA tag support, thus using DSA (with no EtherType) by default. This reminds me of this discussion with Tobias Waldekranz. The FMan parser sees errors due to the somewhat controversial Marvell original DSA tag decisions: https://lore.kernel.org/netdev/20210323102326.3677940-1-tobias@waldekranz.com/ Could you please force EDSA with this switch and see if the packet loss situation improves? Simplest way would be: ip link set eth0 down echo edsa > /sys/class/net/eth0/dsa/tagging ip link set lan1 up If this helps, I would recommend reading Documentation/devicetree/bindings/net/dsa/dsa-port.yaml to see how to make this board use edsa persistently.
