The Ethernet controller found in the Armada 38x SoC's family support
TCP/IP checksumming with frame sizes larger than 1600 bytes, however
only on port 0.

This commit enables this feature by using 'marvell,armada-xp-neta' in
'ethernet at 70000' node.

As it's clear that they are not 100% backwards compatible, please
add a SoC specific compatible string here as well, like

        compatible = "marvell,armada-380-neta", "marvell,armada-xp-neta";

Wouldn't be one sufficient ("marvell,armada-380-neta")?

Maybe also leave the 370 string in place.

Now 370 string disables ip checksum for jumbo frames, so I don't think
it's appropriate to keep it for port 0.

Best regards,
