[PATCH 2/2] ARM: mvebu: disable IP checksum with jumbo frames for Armada 370

[Simon Guinot <simon.guinot@sequanux.org>]

The Ethernet controller found in Armada 370 SoCs don't support TCP/IP
checksumming with frames largest than 1600 Bytes.

This patch sets accordingly the tx_csum_limit property in Ethernet nodes
for Armada 370.
