Subject: [dpdk-dev] [PATCH v7 04/10] i40e:support VxLAN packet identification in i40e
Date: Thu, 23 Oct 2014 21:18:54 +0800 [thread overview]
Message-ID: <1414070340-19128-5-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1414070340-19128-1-git-send-email-jijiang.liu@intel.com>
Implement the configuration API of VxLAN destination UDP port in librte_pmd_i40e,
and add new Rx offload flags for supporting VXLAN packet offload.
