+IAVF: default RSS configuration
+===============================
+
+Description
+===========
+
+DPDK-21.02 improved iavf default RSS, major feature are:
+
+ - support IAVF to use port config to set ip/udp/tcp/sctp RSS, other rss_type like gtpu/l2tpv3/esp/ah will be
+   rejected, they should only be supported used in RTE_FLOW::
+
+    port config all rss ip/udp/tcp/sctp
+
+ - default RSS should be overwritten but not append, for example, set udp, then set tcp, it will be tcp at the end.
+ - any kernel PF enabled default RSS should be disabled, it requires ice base driver >= 1.3.0.
+ - only support Intel E810 series cards now, but not support Intel 700 series cards.
+
+Prerequisites
+=============
+
+1. NIC requires:
+
+   - Intel E810 series ethernet cards: columbiaville_25g, columbiaville_100g, etc.
+
+2. insmod ice.ko, and bind PF to ice.
+
+3. create a VF from a PF in DUT, set mac address for this VF::
+
+    echo 1 > /sys/bus/pci/devices/0000\:18\:00.0/sriov_numvfs
+    ip link set enp24s0f0 vf 0 mac 00:11:22:33:44:55
+
+4. bind VF to vfio-pci::
+
+    modprobe vfio-pci
+    usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:18:01.0
+
+5. launch testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- -i --rxq=16 --txq=16
+    testpmd>set fwd rxonly
+    testpmd>set verbose 1
+    testpmd> start
+
+Basic test steps
+----------------
+
+1. set rss function
+
+* testpmd command-line options::
+
+   --rss-ip: set ip RSS.
+   --rss-udp: set udp RSS.
+   --disable-rss: disable RSS.
+
+  RSS is on by default.
+
+* testpmd runtime functions::
+
+   port config all rss ip/udp/tcp/sctp/none/all
+
+  * The ``none`` option is equivalent to the ``--disable-rss`` command-line option.
+  * The `` ip`` option is equivalent to the ``--rss-ip`` command-line option.
+  * The `` udp`` option is equivalent to the ``--rss-udp`` command-line option.
+
+.. note::
+
+    - IP_RSS: ip/udp/tcp/sctp pkts use L3 ipv4()/ipv6() get hash values.
+    - UDP(TCP/SCTP)_RSS: only UDP(TCP/SCTP) pkts use L4 UDP()/TCP()/SCTP() get hash values, other pkts have no hash values.
+
+2. transmit different protocol packets, and check hash results based on following table. (take IP RSS for example)
+
+ a. transmit MAC_IPV4_PAY packet::
+
+      Ether(dst="00:11:22:33:44:55")/IP(src="192.168.0.2",dst="192.168.0.3")/("X"*40)
+
+ b. check hash results that `RSS hash=0x5bf8517c` in the output::
+
+      testpmd> port 0/queue 12: received 1 packets(have hash)
+      src=00:1E:67:56:C8:2B - dst=00:11:22:33:44:55 - type=0x0800 - length=74 - nb_segs=1 - RSS hash=0x5bf8517c - RSS
+      queue=0xc - hw ptype: L2_ETHER L3_IPV4_EXT_UNKNOWN L4_NONFRAG  - sw ptype: L2_ETHER L3_IPV4  - l2_len=14 -
+      l3_len=20 - Receive queue=0xc
+      ol_flags: PKT_RX_RSS_HASH PKT_RX_L4_CKSUM_GOOD PKT_RX_IP_CKSUM_GOOD PKT_RX_OUTER_L4_CKSUM_UNKNOWN
+
+ c. transmit MAC_IPV4_UDP packet::
+
+      Ether(dst="00:11:22:33:44:55")/IP(src="192.168.0.2",dst="192.168.0.3")/UDP(sport=1024,dport=1025)/("X"*40)
+
+ d. check hash results that `RSS hash=0x5bf8517c` in the output, MAC_IPV4_UDP has same hash vaule with MAC_IPV4_PAY,
+    that's becuse they have same IP dst and src::
+
+      testpmd> port 0/queue 12: received 1 packets(have hash)
+      src=00:1E:67:56:C8:2B - dst=00:11:22:33:44:55 - type=0x0800 - length=82 - nb_segs=1 - RSS hash=0x5bf8517c - RSS
+      queue=0xc - hw ptype: L2_ETHER L3_IPV4_EXT_UNKNOWN L4_UDP  - sw ptype: L2_ETHER L3_IPV4 L4_UDP  - l2_len=14 -
+      l3_len=20 - l4_len=8 - Receive queue=0xc
+      ol_flags: PKT_RX_RSS_HASH PKT_RX_L4_CKSUM_GOOD PKT_RX_IP_CKSUM_GOOD PKT_RX_OUTER_L4_CKSUM_UNKNOWN
+
+.. note::
+
+    Some packets don't have string `RSS hash` in the output, as their hash function are disabled.
