#1278858 — [PATCH v3 net 6/6] net: mvneta: enable IP checksum with jumbo frames for Armada 38x on Port0

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 it by setting 'tx-csum-limit' to 9800B in
'ethernet@70000' node.

This commit should not be merged through the network subsystem but
through mvebu and then arm-soc.

Indeed we tried to centralize all the dts change in only one subsystem
to reduce the merge conflict.

Could you rename it in "mvebu: dts: enable IP checksum with jumbo frames
for Armada 38x on Port0" ?

I will applied on in mvebu/dts as soon as the network part will be
applied.

Thanks,

Gregory
