Subject: [PATCH RFC 6/6] net/faraday: Enable offload checksum according to device-tree
Date: Mon, 9 Nov 2015 11:10:06 +1100 [thread overview]
Message-ID: <1447027806-4744-7-git-send-email-gwshan@linux.vnet.ibm.com> (raw)
In-Reply-To: <1447027806-4744-1-git-send-email-gwshan@linux.vnet.ibm.com>
This enables IP/UDP/TCP offload checksum according to information
passed on from bootloader through device-tree. The offload doesn't
working properly when the interface works in NCSI mode.
