Subject: [PATCH 11/11] fcoe: fcoe fc crc offload indication by skb->ip_summed
Date: Fri, 27 Feb 2009 14:07:31 -0800 [thread overview]
Message-ID: <20090227220731.4987.84514.stgit.yi.zou@intel.com> (raw)
In-Reply-To: <20090227220034.4987.50755.stgit@localhost.localdomain>
If LLD supports FCCRC offload, it should set ip_summed to be
CHECKSUM_UNNECESSARY so we don't have to do CRC check again.
