Subject: [PATCH v3 net 6/6] net: mvneta: enable IP checksum with jumbo frames for Armada 38x on Port0
Date: Fri, 27 Nov 2015 16:44:26 +0100 [thread overview]
Message-ID: <1448639066-13074-7-git-send-email-mw@semihalf.com> (raw)
In-Reply-To: <1448639066-13074-1-git-send-email-mw@semihalf.com>
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.
