Subject: [dpdk-dev] [PATCH v8 07/10] i40e:implement the API of VxLAN filter in librte_pmd_i40e
Date: Mon, 27 Oct 2014 10:13:23 +0800
Message-ID: <1414376006-31402-8-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1414376006-31402-1-git-send-email-jijiang.liu@intel.com>

The filter types supported are listed below for VxLAN:
   1. Inner MAC and Inner VLAN ID.
   2. Inner MAC address, inner VLAN ID and tenant ID.
   3. Inner MAC and tenant ID.
   4. Inner MAC address.
   5. Outer MAC address, tenant ID and inner MAC address.
