Subject: [PATCH RFC v1 7/7] net/faraday: Enable offload checksum according to device-tree
Date: Tue,  6 Oct 2015 14:09:49 +1100	[thread overview]
Message-ID: <1444100989-3437-8-git-send-email-gwshan@linux.vnet.ibm.com> (raw)
In-Reply-To: <1444100989-3437-1-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.
