+NIC PF Smoke Test
+==================
+
+Description
+===========
+Test the basic functions of dpdk.
+1. Port connection status.
+2. Launch testpmd normally.
+3. Basic rx and tx.
+
+Prerequisites
+=============
+
+1. Hardware:
+
+ niantic/fortville/columbiaville
+
+2. Software:
+
+ dpdk: http://dpdk.org/git/dpdk
+ scapy: http://www.secdev.org/projects/scapy/
+
+3. Compile DPDK::
+
+ CC=gcc meson -Denable_kmods=True -Dlibdir=lib --default-library=static x86_64-native-linuxapp-gcc
+ ninja -C x86_64-native-linuxapp-gcc
+
+4. Get the pci device id of DUT, for example::
+
+ ./usertools/dpdk-devbind.py -s
+
+ 0000:86:00.0 'Device 1593' if=enp134s0f0 drv=ice unused=vfio-pci
+
+7. Bind PF to dpdk driver::
+
+ modprobe vfio-pci
+ ./usertools/dpdk-devbind.py -b vfio-pci 0000:86:00.0
+
+8. Launch dpdk on PF::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -a 0000:86:00.0 --file-prefix=pf -- -i --max-pkt-len=9600 --tx-offloads=0x00008000 --rxq=4 --txq=4
+ testpmd> set fwd mac
+ testpmd> set verbose 3
+ testpmd> start
+ testpmd> show port info all
+
+Test Case 1: test enable and disable jumbo frame
+====================================================
+1. set fwd mode is mac::
+
+ testpmd> set fwd mac
+ testpmd> set verbose 3
+ testpmd> start
+
+2. Send a packet with size 9601 bytes ::
+
+ testpmd> show port stats 0
+
+ ######################## NIC statistics for port 0 ########################
+ RX-packets: 0 RX-errors: 1 RX-bytes: 0
+ TX-packets: 0 TX-errors: 0 TX-bytes: 0
+ ############################################################################
+
+Verify that TX-bytes on port 0 and RX-bytes on port 0 are 0.
+
+3. Send a packet with size 9600 bytes ::
+
+ testpmd> show port stats 0
+
+ ######################## NIC statistics for port 0 ########################
+ RX-packets: 1 RX-errors: 0 RX-bytes: 9600
+ TX-packets: 1 TX-errors: 0 TX-bytes: 9600
+ ############################################################################
+
+Verify that TX-bytes on port 0 and RX-bytes on port 0 are 9600.
+
+4. Set mtu is 1500 ::
+
+ testpmd> port config mtu 1500
+
+5. Send a packet with size 1518 bytes ::
+
+ testpmd> show port stats 0
+
+ ######################## NIC statistics for port 0 ########################
+ RX-packets: 1 RX-errors: 0 RX-bytes: 1518
+ TX-packets: 1 TX-errors: 0 TX-bytes: 1518
+ ############################################################################
+
+Verify that TX-bytes on port 0 and RX-bytes on port 0 are 1518
+
+7. Send a packet with size 1519 bytes ::
+
+ testpmd> show port stats 0
+
+ ######################## NIC statistics for port 0 ########################
+ RX-packets: 0 RX-errors: 1 RX-bytes: 0
+ TX-packets: 0 TX-errors: 0 TX-bytes: 0
+ ############################################################################
+
+Verify that TX-bytes on port 0 and RX-bytes on port 1 are 0
+
+Test Case 2: test RSS
+====================================================
+1. set fwd mode is rxonly::
+
+ testpmd> set fwd rxonly
+ testpmd> set verbose 1
+ testpmd> start
+
+4. Send different hash types' packets with different keywords, then check rx port
+ could receive packets by different queues::
+
+ sendp([Ether(dst="00:01:23:45:67:89")/IP(src="192.168.0.4", dst=RandIP())], iface="eth3")
+
+Test Case 3: test reset RX/TX queues
+====================================================
+1. Run ``port stop all`` to stop all ports.
+
+2. Run ``port config all rxq 2`` to change the number of receiving queues to two.
+
+3. Run ``port config all txq 2`` to change the number of transmitting queues to two.
+
+4. Run ``port start all`` to restart all ports.
+
+5. Check with ``show config rxtx`` that the configuration for these parameters changed.
+
+6. Run ``start`` again to restart the forwarding, then start packet generator to transmit
+ and receive packets, and check if testpmd is able to receive and forward packets
+ successfully.
