+Test Cases:  Rx interrupt
+====================================================================
+
+Test case: rx interrupt
+

+1. build build l3fwd power
+    make -C examples/l3fwd-power RTE_SDK=`pwd` T=x86_64-native-linuxapp-gcc
+
+2. build two VFs with igb_uio
+   modprobe uio;
+   insmod x86_64-native-linuxapp-gcc/kmod/igb_uio.ko;
+   # ./usertools/dpdk-devbind.py --bind=igb_uio 18:02.0 18:0a.0
+

+    send traffic and vefify throughput
+
+Test Csse: scalar/bulk vf performance
+
+1. change CONFIG_RTE_LIBRTE_AVF_INC_VECTOR=n in config/common_base, and rebuild dpdk
+
+2. repeat test steps 2-4 in above test case: vector vf performance.
