+vhost event idx interrupt mode with CBDMA test plan
+===================================================
+
+Description
+===========
+
+Vhost event idx interrupt need test with l3fwd-power sample with CBDMA channel, 
+send small packets from virtio-net to vhost side, check vhost-user cores can be
+wakeup status，and vhost-user cores should be sleep status after stop sending 
+packets from virtioside. 
+
+Note:
+1.For packed virtqueue test, need using qemu version > 4.2.0.
+2.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd.
+
+Prerequisites
+=============
+Topology
+--------
+Test flow: Virtio-net --> Vhost-user
+
+General set up
+--------------
+1. Compile DPDK::
+
+    # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static <dpdk build dir>
+    # ninja -C <dpdk build dir> -j 110
+    For example:
+    CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static x86_64-native-linuxapp-gcc
+    ninja -C x86_64-native-linuxapp-gcc -j 110
