[PATCH v4 net 6/6] mvebu: dts: enable IP checksum with jumbo frames for Armada 38x on Port0

From: Marcin Wojtas
Date: Mon Nov 30 2015 - 07:28:11 EST


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.
