+CVL: CVL enable RSS with checksum as inputset
+=============================================
+
+Description
+===========
+
+Enable CVL PF/IAVF RSS with checksum as inputset.
+1. distribute ipv4 packet into queues based on the hash value of checksum.
+2. distribute tcp / udp packet into queues based on hash value of l4 checksum.

+
+Prerequisites
+=============
+
+1. Hardware:
+
+   - Intel E810 series ethernet cards: columbiaville_25g/columbiaville_100g/
+
+2. Software:
+
+   - dpdk: http://dpdk.org/git/dpdk
+   - scapy: http://www.secdev.org/projects/scapy/
+
+.. note::
+
+   This rss feature designed for CVL NIC 25G and 100g, so below the case only support CVL nic.
+
+3. For PF, bind the CVL port to dpdk driver in DUT::
+
+    modprobe vfio-pci
+    ./usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:3b:00.0
+
+4. For VF::
+
+    echo 1 > /sys/bus/pci/devices/0000\:3b\:00.0/sriov_numvfs
+    ip link set enp59s0f0 vf 0 mac 00:11:22:33:44:55
+    ./usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:3b:01.0
+
+.. note::
+
+   The kernel must be >= 3.6+ and VT-d must be enabled in bios.
+
+4. Launch the testpmd to configuration queue of rx and tx number 16 in DUT::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 6 -- -i --rxq=16 --txq=16 --disable-rss --rxd=384 --txd=384
+    testpmd> set fwd rxonly
+    testpmd> set verbose 1
+    testpmd> start
+
+Default parameters
+------------------
+
+   MAC::
+
+    [Dest MAC]: 00:11:22:33:44:55
+    [Src MAC]: 52:00:00:00:00:00
+
+   IPv4::
+
+    [Dest IP]: 192.168.0.2
+    [Source IP]: 192.168.0.1
+
+   IPv6::
+
+    [Source IPv6]: ABAB:910A:2222:5498:8475:1111:3900:1010
+    [Dest IPv6]: CDCD:910A:2222:5498:8475:1111:3900:2020
+
+   UDP/TCP/SCTP::
+
+    [Source Port]: 22
+    [Dest Port]: 23
+
+
+Common Test steps
+=================
+all the test cases run the same test steps as below:
+
+1. validate rule.
+2. create rule and list rule.
+3. send a basic hit pattern packet,record the hash value,
+   check the packet is distributed to queues by RSS.
+4. send hit pattern packet with changed input set in the rule.
+   check the received packet have different hash value with basic packet.
+   check the packet is distributed to queues by rss.
+5. send hit pattern packet with changed input set not in the rule.
+   check the received packet have same hash value with the basic packet.
+   check the packet is distributed to queues by rss.
+   note: if there is not this type packet in the case, omit this step.
+6. send not hit pattern packets with input set in the rule.
+   check the received packets have not hash value, and distributed to queue 0.
+   note: if there is not this type packet in the case, omit this step.
+7. distroy the rule and list rule.
+8. send same packet with step 3.
+   check the received packets have not hash value, and distributed to queue 0.

+Test case 8: Checksum for different payload length
+==================================================
+1. launch testpmd without "--disable-rss"::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 6 -- -i --rxq=16 --txq=16
+    testpmd> set fwd rxonly
+    testpmd> set verbose 1
+    testpmd> start
+
+2. Send packets with different payload length::
+
+    p1=Ether(dst="00:11:22:33:44:55", src="52:00:00:00:00:00")/IP()/("X"*48)

+
+   Check all the packets received have same hash value.
+
+3. create RSS rule of 5-tuple inputset for each packet type::
+
+    flow create 0 ingress pattern eth / ipv4 / udp / end actions rss types ipv4-udp  end queues end / end
+    flow create 0 ingress pattern eth / ipv4 / tcp / end actions rss types ipv4-tcp  end queues end / end
+    flow create 0 ingress pattern eth / ipv4 / sctp / end actions rss types ipv4-sctp  end queues end / end
+
+4. Send packets of step 2.
+   Check the received packets with same packet type have same hash value.
+
+5. create RSS rule of l4-chksum inputset for each packet type::
+
+    flow create 0 ingress pattern eth / ipv4 / udp / end actions rss types l4-chksum  end queues end / end
+    flow create 0 ingress pattern eth / ipv4 / tcp / end actions rss types l4-chksum  end queues end / end

+8. Send packets of step 2.
+   Check the IPV4/UDP/TCP/SCTP packets with different payload length have different hash value.
+
+Test case 9: Set HW csum, flow rule doesn’t impact RX checksum and TX checksum
+==============================================================================
+1. launch testpmd without "--disable-rss"::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 6 -- -i --rxq=16 --txq=16
+
+2. Set tx checksum::
+
+    port stop all
+    set fwd csum
+    csum set ip hw 0
+    csum set udp hw 0
+    csum set tcp hw 0
+    csum set sctp hw 0
+    port start all
+    set verbose 1
+    start
+
+3. Capture the tx packet at tester port::
+
+    tcpdump -i enp216s0f0 -Q in -e -n -v -x
+
+4. Send packets::
+
+    p1=Ether(dst="00:11:22:33:44:55", src="52:00:00:00:00:00")/IP(src="192.168.0.1", chksum=0xfff3)/("X"*48)

+
+   Check rx checksum good or bad, check if the tx checksum correct.
+
+5. Create rss rules with chsum as inputset::
+
+    flow create 0 ingress pattern eth / ipv4 / end actions rss types ipv4-chksum end queues end / end
+    flow create 0 ingress pattern eth / ipv4 / tcp / end actions rss types l4-chksum end queues end / end
+    flow create 0 ingress pattern eth / ipv4 / udp / end actions rss types l4-chksum end queues end / end
+    flow create 0 ingress pattern eth / ipv4 / sctp / end actions rss types l4-chksum end queues end / end
+    flow create 0 ingress pattern eth / ipv6 / tcp / end actions rss types l4-chksum end queues end / end
+    flow create 0 ingress pattern eth / ipv6 / udp / end actions rss types l4-chksum end queues end / end
+    flow create 0 ingress pattern eth / ipv6 / sctp / end actions rss types l4-chksum end queues end / end
+
+6. Send the same packets, check the hash value changed, check rx and tx checksum, get the same result.
