Subject: [PATCH] mvebu: dts: 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.
