Subject: [dpdk-dev] [PATCH] i40e:remove unlikely check in i40e_xmit_pkts for checksum offload
Date: Tue, 4 Aug 2015 15:57:11 +0800 [thread overview]
Message-ID: <1438675031-13872-1-git-send-email-jijiang.liu@intel.com> (raw)
The i40e_xmit_pkts() is called, which often means HW offload is used here, so we had better remove 'unlikely' check for checksum offload.
