+=========================================
+Transmit Segmentation Offload (TSO) Tests
+=========================================
+
+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
+Intel® Ethernet Converged Network Adapter XL710-QDA2. 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
+=============
+
+Hardware:
+ Intel® Ethernet 700 Series, Intel® Ethernet 800 Series and 82599/500 Series
+
+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::
+
+ ifconfig <tx port> mtu 9000
+ 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
+ csum set ip hw 0
+ csum set udp hw 0
+ csum set tcp hw 0
+ csum set sctp hw 0
+ set fwd csum
+
+ # enable TSO on tx port
+ *tso set 800 1
+
+
+
+Test case: TSO performance
+==========================
+
+Set the packet stream to be sent out from packet generator before testing as
+below.

+
+The -n command is used to select the number of memory channels. It should match the
+number of memory channels on that setup.
