Subject: [net-next 6/6] ixgbevf: add check for CHECKSUM_PARTIAL when doing TSO
Date: Thu, 27 Feb 2014 20:32:45 -0800	[thread overview]
Message-ID: <1393561965-3688-7-git-send-email-aaron.f.brown@intel.com> (raw)
In-Reply-To: <1393561965-3688-1-git-send-email-aaron.f.brown@intel.com>

From: Emil Tantilov <emil.s.tantilov@intel.com>

This patch adds check for CHECKSUM_PARTIAL to avoid the skb_is_gso check
in ixgbevf_tso(). It should reduce overhead for workloads that are not using
TSO or checksum offloads. It is the same as in ixgbe.
