+DPDK PMD for AF_XDP Tests
+=========================
+
+Description
+===========
+
+AF_XDP is a proposed faster version of AF_PACKET interface in Linux.
+This test plan is to analysis the performance of DPDK PMD for AF_XDP.
+
+Prerequisites
+=============
+
+1. Hardware::
+
+    I40e 25G*2
+    enp216s0f0 <---> IXIA_port_0
+    enp216s0f1 <---> IXIA_port_0
+
+2. The NIC is located on the socket 1, so we define the cores of socket 1.
+
+3. Take the kernel >= v5.1-rc1, build kernel and replace your host
+   kernel with it.
+   Update compiler to the proper version.
+   Make sure you turn on XDP sockets when compiling::
+
+    Networking support -->
+         Networking options -->
+                 [ * ] XDP sockets
+
+4. Build libbpf in tools/lib/bpf::
+
+    cd tools/lib/bpf
+    make
+
+   Then copy the libbpf.a and libbpf.so to /usr/lib64
+
+5. Set DUT port only has one queue::
+
+    ethtool -L enp216s0f0 combined 1
+    ethtool -L enp216s0f1 combined 1
+
+6. Explicitly enable AF_XDP pmd by adding below line to
+   config/common_linux::
+
+    CONFIG_RTE_LIBRTE_PMD_AF_XDP=y
+
+Test case 1: 1 port, 1 kernel core, 1 user core
+===============================================
+
+1. Start the testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/testpmd -l 30,31 --no-pci -n 6 \
+    --vdev net_af_xdp0,iface=enp216s0f0,queue=0 --file-prefix=port0 \
+    --socket-mem 1024,1024 -- -a --nb-cores=1 -i --rxq=1 --txq=1 \
+    --port-topology=loop
+
+2. Assign the kernel core::
+
+    ./set_irq_affinity 33 enp216s0f0
+
+3. Send packet with packet generator with different packet size,
+   from 64 bytes to 1518 bytes, check the throughput.
+
+Test case 2: 2 ports, 2 kernel cores, 1 user cores
+==================================================
+
+1. Start the testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/testpmd -l 30,32 --no-pci -n 6 \
+    --vdev net_af_xdp0,iface=enp216s0f0,queue=0 --file-prefix=port0 \
+    --socket-mem 1024,1024 -- -a  --nb-cores=1 -i --rxq=1 --txq=1 \
+    --port-topology=loop
+
+    ./x86_64-native-linuxapp-gcc/app/testpmd -l 31,33 --no-pci -n 6 \
+    --vdev net_af_xdp1,iface=enp216s0f1,queue=0 --file-prefix=port1 \
+    --socket-mem 1024,1024 -- -a --nb-cores=1 -i --rxq=1 --txq=1 \
+    --port-topology=loop
+
+2. Assign the kernel core::
+
+    ./set_irq_affinity 35 enp216s0f0
+    ./set_irq_affinity 36 enp216s0f1
+
+3. Send packet with packet generator with different packet size,
+   from 64 bytes to 1518 bytes, check the throughput.
