Subject: [PATCH 7/7] fcoe: fcoe fc crc offload indication by skb->ip_summed
Date: Thu, 19 Feb 2009 12:50:31 -0700 [thread overview]
Message-ID: <20090219195031.22270.35911.stgit.yi.zou@intel.com> (raw)
In-Reply-To: <20090219194734.22270.8445.stgit@zychengdu.jf.intel.com>
If LLD supports FCCRC offload, it should set ip_summed to be
CHECKSUM_UNNECESSARY so we don't have to do CRC check again.
