+Testing of TSO Support in DPDK
+==============================================
+
+
+Description
+===========
+
+This document provides the plan for testing the TSO(Transmit Segmentation
+Offload, also called Large Send offload - LSO) feature of
+Intel Ethernet Controller, including Intel 82599 10GbE Ethernet Controller and
+Fortville 40GbE Ethernet Controller. TSO enables the TCP/IP stack to
+pass to the network device a larger ULP datagram than the Maximum Transmit
+Unit Size (MTU). NIC divides the large ULP datagram to multiple segments
+according to the MTU size.
+
+
+Prerequisites
+=============
+
+The DUT must take one of the Ethernet controller ports connected to a port on another
+device that is controlled by the Scapy packet generator.
+
+The Ethernet interface identifier of the port that Scapy will use must be known.
+On tester, all offload feature should be disabled on tx port, and start rx port capture:
+ ethtool -K <tx port> rx off tx off tso off gso off gro off lro off
+ ip l set <tx port> up
+ tcpdump -n -e -i <rx port> -s 0 -w /tmp/cap
+
+
+On DUT, run pmd with parameter "--enable-rx-cksum". Then enable TSO on tx port
+and checksum on rx port. The test commands is below:
+ #enable hw checksum on rx port
+ tx_checksum set ip hw 0
+ tx_checksum set udp hw 0
+ tx_checksum set tcp hw 0
+ tx_checksum set sctp hw 0
+ set fwd csum
+
+ # enable TSO on tx port
+ *tso set 800 1
+
+
+Test case: csum fwd engine, use TSO
+====================================================
+
+This test uses ``Scapy`` to send out one large TCP package. The dut forwards package
+with TSO enable on tx port while rx port turns checksum on. After package send out
+by TSO on tx port, the tester receives multiple small TCP package.
+
+Turn off tx port by ethtool on tester::
+ ethtool -K <tx port> rx off tx off tso off gso off gro off lro off
+ ip l set <tx port> up
+capture package rx port on tester::
+ tcpdump -n -e -i <rx port> -s 0 -w /tmp/cap
+
+Launch the userland ``testpmd`` application on DUT as follows::
+./x86_64-native-linuxapp-gcc/app/testpmd -c 0xffffffff -n 2 -- -i --rxd=512 --txd=512
+--burst=32 --rxfreet=64 --mbcache=128 --portmask=0x3 --txpt=36 --txht=0 --txwt=0
+--txfreet=32 --txrst=32 --enable-rx-cksum
+ testpmd> set verbose 1
+
+ # enable hw checksum on rx port
+ testpmd> tx_checksum set ip hw 0
+ testpmd> tx_checksum set udp hw 0
+ testpmd> tx_checksum set tcp hw 0
+ testpmd> tx_checksum set sctp hw 0
+ # enable TSO on tx port
+ testpmd> tso set 800 1
+ # set fwd engine and start
+ testpmd> set fwd csum
+ testpmd> start
+
+Test IPv4() in scapy:
+ sendp([Ether(dst="%s", src="52:00:00:00:00:00")/IP(src="192.168.1.1",dst="192.168.1.2")/UDP(sport=1021,dport=1021)/Raw(load="\x50"*%s)], iface="%s")
+
+Test IPv6() in scapy:
+ sendp([Ether(dst="%s", src="52:00:00:00:00:00")/IPv6(src="FE80:0:0:0:200:1FF:FE00:200", dst="3555:5555:6666:6666:7777:7777:8888:8888")/UDP(sport=1021,dport=1021)/Raw(load="\x50"*%s)], iface="%s"
+
+Test case: csum fwd engine, use TSO tunneling
+====================================================
+
+This test uses ``Scapy`` to send out one large TCP package. The dut forwards package
+with TSO enable on tx port while rx port turns checksum on. After package send out
+by TSO on tx port, the tester receives multiple small TCP package.
+
+Turn off tx port by ethtool on tester::
+ ethtool -K <tx port> rx off tx off tso off gso off gro off lro off
+ ip l set <tx port> up
+capture package rx port on tester::
+ tcpdump -n -e -i <rx port> -s 0 -w /tmp/cap
+
+Launch the userland ``testpmd`` application on DUT as follows::
+./x86_64-native-linuxapp-gcc/app/testpmd -c 0xffffffff -n 2 -- -i --rxd=512 --txd=512
+--burst=32 --rxfreet=64 --mbcache=128 --portmask=0x3 --txpt=36 --txht=0 --txwt=0
+--txfreet=32 --txrst=32 --enable-rx-cksum
+ testpmd> set verbose 1
+
+ # enable hw checksum on rx port
+ testpmd> tx_checksum set ip hw 0
+ testpmd> tx_checksum set udp hw 0
+ testpmd> tx_checksum set tcp hw 0
+ testpmd> tx_checksum set sctp hw 0
+ testpmd> tx_checksum set vxlan hw 0
+ testpmd> tx_checksum set nvgre hw 0
+ # enable TSO on tx port
+ testpmd> tso set 800 1
+ # set fwd engine and start
+ testpmd> set fwd csum
+ testpmd> start
+
+Test vxlan() in scapy:
+ sendp([Ether(dst="%s",src="52:00:00:00:00:00")/IP(src="192.168.1.1",dst="192.168.1.2")/UDP(sport=1021,dport=4789)/VXLAN(vni=1234)/Ether(dst=%s,src="52:00:00:00:00:00")/IP(src="192.168.1.1",dst="192.168.1.2")/UDP(sport=1021,dport=1021)/Raw(load="\x50"*%s)], iface="%s"
+
+Test nvgre() in scapy:
+ sendp([Ether(dst="%s",src="52:00:00:00:00:00")/IP(src="192.168.1.1",dst="192.168.1.2",proto=47)/NVGRE()/Ether(dst=%s,src="52:00:00:00:00:00")/IP(src="192.168.1.1",dst="192.168.1.2")/TCP(sport="1021",dport="1021")/("X"*%s)], iface="%s")
+
+Test case: TSO performance
+====================================================
+Set the packet stream to be sent out from packet generater before testing as
+below.
+
++-------+---------+---------+---------+----------+----------+
+| Frame | 1S/1C/1T| 1S/1C/1T| 1S/2C/1T| 1S/2C/2T | 1S/2C/2T |
+| Size | | | | | |
++-------+---------+---------+---------+----------+----------+
+| 64 | | | | | |
++-------+---------+---------+---------+----------+----------+
+| 65 | | | | | |
++-------+---------+---------+---------+----------+----------+
+| 128 | | | | | |
++-------+---------+---------+---------+----------+----------+
+| 256 | | | | | |
++-------+---------+---------+---------+----------+----------+
+| 512 | | | | | |
++-------+---------+---------+---------+----------+----------+
+| 1024 | | | | | |
++-------+---------+---------+---------+----------+----------+
+| 1280 | | | | | |
++-------+---------+---------+---------+----------+----------+
+| 1518 | | | | | |
++-------+---------+---------+---------+----------+----------+
+
+Then run the test application as below::
+./x86_64-native-linuxapp-gcc/app/testpmd -c 0xffffffff -n 2 -- -i --rxd=512 --txd=512
+--burst=32 --rxfreet=64 --mbcache=128 --portmask=0x3 --txpt=36 --txht=0 --txwt=0
+--txfreet=32 --txrst=32 --enable-rx-cksum
+The -n command is used to select the number of memory channels. It should match the
+number of memory channels on that setup.
