-PMD RX/TX Checksum Offload
-==========================
-
-The support of RX/TX L3/L4 Checksum offload features by Poll Mode Drivers consists in:
-
-On the RX side:
-- Verify IPv4 checksum by hardware for received packets.
-- Verify UDP/TCP/SCTP checksum by hardware for received packets.
-
-On the TX side:
-
-- IPv4 checksum insertion by hardware in transmitted packets.
-- IPv4/UDP checksum insertion by hardware in transmitted packets.
-- IPv4/TCP checksum insertion by hardware in transmitted packets.
-- IPv4/SCTP checksum insertion by hardware in transmitted packets (sctp 
-        length in 4 bytes).
-- IPv6/UDP checksum insertion by hardware in transmitted packets.
-- IPv6/TCP checksum insertion by hardware in transmitted packets.
-- IPv6/SCTP checksum insertion by hardware in transmitted packets (sctp 
-        length in 4 bytes).
-
-RX side, the L3/L4 checksum offload by hardware can be enabled with the
-following command of the ``testpmd`` application::
-
-   enable-rx-checksum
-
-TX side, the insertion of a L3/L4 checksum by hardware can be enabled with the
-following command of the ``testpmd`` application and running in a dedicated
-tx checksum mode::
-
-   set fwd csum
-   tx_checksum set mask port_id
-
-The transmission of packet is done with the ``start`` command of the ``testpmd`` 
-application that will receive packets and then transmit the packet out on all 
-configured ports. ``mask`` is used to indicated what hardware checksum
-offload is required on the ``port_id``. Please check the NIC datasheet for the 
-corrresponding Hardware limits::
-
-      bit 0 - insert ip checksum offload if set 
-      bit 1 - insert udp checksum offload if set 
-      bit 2 - insert tcp checksum offload if set
-      bit 3 - insert sctp checksum offload if set
-
-
-Prerequisites
-=============
-
-Support igb_uio and vfio driver, if used vfio, kernel need 3.6+ and enable vt-d in bios.
-When used vfio , used "modprobe vfio" and "modprobe vfio-pci" insmod vfiod driver, then used
-"./tools/dpdk_nic_bind.py --bind=vfio-pci device_bus_id" to bind vfio driver to test driver.
- 
-Assuming that ports ``0`` and ``2`` are connected to a traffic generator,
-launch the ``testpmd`` with the following arguments::
-  
-  ./build/app/testpmd -cffffff -n 1 -- -i --burst=1 --txpt=32 \
-  --txht=8 --txwt=0 --txfreet=0 --rxfreet=64 --mbcache=250 --portmask=0x5
-  enable-rx-checksum
-
-Set the verbose level to 1 to display informations for each received packet::
-
-  testpmd> set verbose 1 
-
-Test Case: Validate checksum on the receive packet
-==================================================
-
-Setup the ``csum`` forwarding mode::
-
-  testpmd> set fwd csum
-  Set csum packet forwarding mode
-
-Start the packet forwarding::
-  
-  testpmd> start
-    csum packet forwarding - CRC stripping disabled - packets/burst=32
-    nb forwarding cores=1 - nb forwarding ports=10
-    RX queues=1 - RX desc=128 - RX free threshold=64
-    RX threshold registers: pthresh=8 hthresh=8 wthresh=4
-    TX queues=1 - TX desc=512 - TX free threshold=0
-    TX threshold registers: pthresh=32 hthresh=8 wthresh=8
-
-Configure the traffic generator to send the multiple packets with the following 
-combination: good/bad ip checksum + good/bad udp/tcp checksum.
-
-Except that SCTP header + payload length must be a multiple of 4 bytes.
-IPv4 + UDP/TCP packet length can range from the minimum length to 1518 bytes.
-
-Then verify that how many packets found with Bad-ipcsum or Bad-l4csum::
-
-  testpmd> stop
-  ---------------------- Forward statistics for port 0  ----------------------
-  RX-packets: 0              RX-dropped: 0             RX-total: 0
-  Bad-ipcsum: 0              Bad-l4csum: 0              
-  TX-packets: 0              TX-dropped: 0             TX-total: 0
-  ----------------------------------------------------------------------------
-
-
-Test Case: Insert IPv4/IPv6 UDP/TCP/SCTP checksum on the transmit packet
-========================================================================
-
-Setup the ``csum`` forwarding mode::
-
-  testpmd> set fwd csum
-  Set csum packet forwarding mode
-
-Enable the IPv4/UDP/TCP/SCTP checksum offload on port 0::
-  
-  testpmd> tx_checksum set 0xf 0
-  testpmd> start
-    csum packet forwarding - CRC stripping disabled - packets/burst=32
-    nb forwarding cores=1 - nb forwarding ports=10
-    RX queues=1 - RX desc=128 - RX free threshold=64
-    RX threshold registers: pthresh=8 hthresh=8 wthresh=4
-    TX queues=1 - TX desc=512 - TX free threshold=0
-    TX threshold registers: pthresh=32 hthresh=8 wthresh=8
-
-Configure the traffic generator to send the multiple packets for the following 
-combination: IPv4/UDP, IPv4/TCP, IPv4/SCTP, IPv6/UDP, IPv6/TCP.
-
-Except that SCTP header + payload length must be a multiple of 4 bytes.
-IPv4 + UDP/TCP packet length can range from the minimum length to 1518 bytes.
-
-Then verify that the same number of packet are correctly received on the traffic 
-generator side. And IPv4 checksum, TCP checksum, UDP checksum, SCTP CRC32c need 
-be validated as pass by the IXIA. 
-
-The IPv4 source address will not be changed by testpmd.
-
-
-Test Case: Do not insert IPv4/IPv6 UDP/TCP checksum on the transmit packet
-==========================================================================
-
-Setup the ``csum`` forwarding mode::
-
-  testpmd> set fwd csum
-  Set csum packet forwarding mode
-
-Disable the IPv4/UDP/TCP/SCTP checksum offload on port 0::
-  
-  testpmd> tx_checksum set 0x0 0
-  testpmd> start
-    csum packet forwarding - CRC stripping disabled - packets/burst=32
-    nb forwarding cores=1 - nb forwarding ports=10
-    RX queues=1 - RX desc=128 - RX free threshold=64
-    RX threshold registers: pthresh=8 hthresh=8 wthresh=4
-    TX queues=1 - TX desc=512 - TX free threshold=0
-    TX threshold registers: pthresh=32 hthresh=8 wthresh=8
-
-Configure the traffic generator to send the multiple packets for the follwing
-combination: IPv4/UDP, IPv4/TCP, IPv6/UDP, IPv6/TCP.
-
-IPv4 + UDP/TCP packet length can range from the minimum length to 1518 bytes.
-
-Then verify that the same number of packet are correctly received on the traffic
-generator side. And IPv4 checksum, TCP checksum, UDP checksum need
-be validated as pass by the IXIA. 
-
-The first byte of source IPv4 address will be increment by testpmd. The checksum
-is indeed recalculated by software algorithms.
