+vhost/virtio-user pvp with 4K-pages test plan
+=============================================
+
+Dpdk 19.02 add support for using virtio-user without hugepages. The --no-huge mode was augmented to use memfd-backed memory (on systems that support memfd), to allow using virtio-user-based NICs without hugepages.
+
+Prerequisites
+-------------
+Turn off transparent hugepage in grub by adding GRUB_CMDLINE_LINUX="transparent_hugepage=never"
+
+Test Case1: Basic test vhost/virtio-user with 4K-pages
+======================================================
+
+1. Bind one port to vfio-pci, launch vhost::
+
+    modprobe vfio-pci
+    ./usertools/dpdk-devbind.py --bind=vfio-pci xx:xx.x
+    ./testpmd -l 3-4 -n 4 -m 1024 --no-huge --file-prefix=vhost \
+    --vdev 'net_vhost0,iface=/tmp/vhost-net,queues=1' -- -i --no-numa --socket-num=0
+    testpmd>start
+
+2. Prepare tmpfs with 4K-pages::
+
+    mkdir /mnt/tmpfs_yinan
+    mount tmpfs /mnt/tmpfs_yinan -t tmpfs -o size=4G
+
+3. Launch virtio-user with 4K-pages::
+
+    ./testpmd -l 5-6 -n 4 --no-huge -m 1024 --file-prefix=virtio-user \
+    --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1 -- -i
+    testpmd>start
+
+4. Send packet with packet generator with different packet size,includes [64, 128, 256, 512, 1024, 1518], check the throughput with below command::
+
+    testpmd>show port stats all
