+
+Common steps for launching DCF
+==============================
+
+Generate 1 trust VF on 1 PF, and request 1 DCF on the trust VF.
+PF should grant DCF mode to it.
+
+Generate 4 VFs on PF ::
+
+    echo 4 > /sys/bus/pci/devices/0000:18:00.0/sriov_numvfs
+
+Set a VF as trust ::
+
+    ip link set enp24s0f0 vf 0 trust on
+    ip link set enp27s0f0 vf 0 mac D2:6B:4C:EB:1C:26
+
+Launch dpdk on the VF, request DCF mode ::
+
+    ./usertools/dpdk-devbind.py -b vfio-pci 18:01.0
+    ./x86_64-native-linuxapp-gcc/app/testpmd -l 6-10 -n 4 -w 18:01.0,cap=dcf --file-prefix=vf -- -i
+
+
+Test Case: Launch DCF and do macfwd
+===================================
+
+Execute **common steps** to prepare DCF test environment
+
+Set macfwd ::
+
+    set fwd mac
+    start
+
+Launch tcpdump to sniffer the packets from DCF ::
+
+    tcpdump -i enp24s0f1 -vvv -Q in
+
+Send packets from tester(scapy) to the VF by MAC address(D2:6B:4C:EB:1C:26) ::
+
+    p = Ether(dst="D2:6B:4C:EB:1C:26", src="00:11:22:33:44:55")/IP(src="192.168.1.1",dst="192.168.1.3")/Raw('x'*64)
+    sendp(p, iface=intf, count=100)
+
+Expect tester can get packets which loopbacked by DCF.
+
+
+Test Case: Check default rss for L3
+===================================
+
+DCF data path support RSS packets by default. For L3 packets, input set is IP src/dst.
+For tunneling packets, input set is inner IP src/dst.
+
+Execute **common steps** to prepare DCF test environment
+
+Set rxonly forward mode ::
+
+    set fwd rxonly
+    set verbose 1
+    start
+    
+Send a series packets to check if DCF RSS is correct for IPv4 ::
