+ICE Support Rx Timestamp
+========================
+
+Description
+===========
+The PF driver is able to enable rx timestamp offload, the 64 bits timestamp is able
+to extracted from the flexible Rx descriptor and be stored in mbuf's dynamic field.
+The received packets have timestamp values, and the timestamp values are incremented.
+
+Prerequisites
+=============
+
+Topology
+--------
+DUT port 0 <----> Tester port 0
+
+Hardware
+--------
+Supported NICs: Intel® Ethernet 800 Series E810-XXVDA4/E810-CQ
+
+Software
+--------
+dpdk: http://dpdk.org/git/dpdk
+scapy: http://www.secdev.org/projects/scapy/
+
+General Set Up
+--------------
+1. Compile DPDK::
+
+    # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib --default-library=static <dpdk build dir>
+    # ninja -C <dpdk build dir> -j 110
+
+2. Get the pci device id and interface of DUT and tester.
+   For example, 0000:3b:00.0 and 0000:3b:00.1 is pci device id,
+   ens785f0 and ens785f1 is interface::
+
+    <dpdk dir># ./usertools/dpdk-devbind.py -s
+
+    0000:3b:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
+    0000:3b:00.1 'Device 159b' if=ens785f1 drv=ice unused=vfio-pci
+
+3. Bind the DUT port to dpdk::
+
+    <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>
+
+Test Case
+=========
+Common Steps
+------------
+All the packets in this test plan use below settings:
+dst mac: 68:05:CA:C1:BA:28
+ipv4 src: 192.168.0.2
+ipv4 dst: 192.168.0.3
+ipv6 src: 2001::2
+ipv6 dst: 2001::3
+sport: 1026
+dport: 1027
+count: 3
+
+1. Set fwd engine::
+
+    testpmd> set fwd rxonly
+
+2. Set verbose::
+
+    testpmd> set verbose 1
+
+3. Start testpmd::
+
+    testpmd> start
+
+4. Send ether packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/("X"*480)], iface="<tester interface>",count=<count>)
+
+5. Send ipv4 packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/IP(src="<ipv4 src>",dst="<ipv4 dst>")/("X"*480)], iface="<tester interface>",count=<count>)
+
+6. Send ipv6 packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/IPv6(src="<ipv6 src>",dst="<ipv6 dst>")/("X"*480)], iface="<tester interface>",count=<count>)
+
+7. Send ipv4-udp packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/IP(src="<ipv4 src>",dst="<ipv4 dst>")/UDP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
+
+8. Send ipv6-udp packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/IPv6(src="<ipv6 src>",dst="<ipv6 dst>")/UDP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
+
+9. Send ipv4-tcp packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/IP(src="<ipv4 src>",dst="<ipv4 dst>")/TCP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
+
+10. Send ipv6-tcp packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/IPv6(src="<ipv6 src>",dst="<ipv6 dst>")/TCP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
+
+11. Send ipv4-sctp packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/IP(src="<ipv4 src>",dst="<ipv4 dst>")/SCTP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
+
+12. Send ipv6-sctp packets, record the timestamp values and check the timestamp values are incremented::
+
+    >>> sendp([Ether(dst="<dst mac>")/IPv6(src="<ipv6 src>",dst="<ipv6 dst>")/SCTP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
+
+Test Case 1: Without timestamp, check no timestamp
+--------------------------------------------------
+This case is designed to check no timestamp value while testpmd not enable rx timestamp.
+
+Test Steps
+~~~~~~~~~~
+1. Start testpmd with different command line::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -a 3b:00.0 -- -i --rxq=16 --txq=16
+
+2. Send packets as common steps, check no timestamp value.
+
+Test Case 2: Single queue With timestamp, check timestamp
+---------------------------------------------------------
+This case is designed to check single queue has timestamp values and the timestamp values are incremented.
+
+Test Steps
+~~~~~~~~~~
+1. Start testpmd with different command line::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -a 3b:00.0 -- -i --enable-rx-timestamp
+
+2. Send packets as common steps, check single queue has timestamp values and the timestamp values are incremented.
+
+Test Case 3: Multi queues With timestamp, check timestamp
+---------------------------------------------------------
+This case is designed to check multi queues have timestamp values and the timestamp values are incremented.
+
+Test Steps
+~~~~~~~~~~
+1. Start testpmd with different command line::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -a 3b:00.0 -- -i --rxq=16 --txq=16 --enable-rx-timestamp
+
+2. Send packets as common steps, check multi queues have timestamp values and the timestamp values are incremented.
