6. RX/TX Checksum Offload Tests ¶
The support of RX/TX L3/L4 Checksum offload features by Poll Mode Drivers consists in:
On the RX side:
On the TX side:
RX/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
csum set ip|tcp|udp|sctp|outer-ip|outer-udp hw|sw 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.
6.1. Prerequisites¶
If using vfio the kernel must be >= 3.6+ and VT-d must be enabled in bios.When
using vfio, use the following commands to load the vfio driver and bind it
to the device under test:
modprobe vfio
modprobe vfio-pci
usertools/dpdk-devbind.py --bind=vfio-pci device_bus_id
Assuming that ports 0 and 2 are connected to a traffic generator,
launch the testpmd with the following arguments:
./build/app/dpdk-testpmd -cffffff -n 1 -- -i --burst=1 --txpt=32 \
--txht=8 --txwt=0 --txfreet=0 --rxfreet=64 --mbcache=250 --portmask=0x5
enable-rx-cksum
Set the verbose level to 1 to display information for each received packet:
testpmd> set verbose 1
Due to DPDK 236bc417e2da(app/testpmd: fix MAC header in checksum forward engine) changes the checksum
functions adds switches to control whether to exchange MAC address.
Currently, our test scripts are based on not exchanging MAC addresses, mac-swap needs to be disabled:
testpmd> csum mac-swap off 0
6.2. 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
Start the packet forwarding:
testpmd> port stop all
testpmd> csum set ip hw 0
testpmd> csum set udp hw 0
testpmd> csum set tcp hw 0
testpmd> csum set sctp hw 0
testpmd> port start all
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
Start a packet capture on the tester in the background:
tcpdump -i <iface> -s 65535 -w /tmp/tester/test_checksum_capture.pcap &
Send the following multiple packets from tester for with scapy
combination: IPv4/UDP, IPv4/TCP, IPv4/SCTP, IPv6/UDP, IPv6/TCP:
sendp([Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IP(chksum=0x0)/UDP(chksum=0xf)/("X"*46),
Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IP(chksum=0x0)/TCP(chksum=0xf)/("X"*46),
Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IP(chksum=0x0)/SCTP(chksum=0x0)/("X"*48),
Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IPv6(src="::1")/UDP(chksum=0xf)/("X"*46),
Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IPv6(src="::1")/TCP(chksum=0xf)/("X"*46)],
iface="ens192f0",count=4,inter=0,verbose=False)
Then verify that the same number of packet are correctly received on the tester.
Inspect the pcap file from the packet capture and verify the checksums.
6.3. 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
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
Start a packet capture on the tester in the background:
tcpdump -i <iface> -s 65535 -w /tmp/tester/test_checksum_capture.pcap &
Send the following multiple packets from tester for with scapy
combination: IPv4/UDP, IPv4/TCP, IPv6/UDP, IPv6/TCP:
sendp([Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IP(src="10.0.0.1",chksum=0x0)/UDP(chksum=0xf)/("X"*46),
Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IP(src="10.0.0.1",chksum=0x0)/TCP(chksum=0xf)/("X"*46),
Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IPv6(src="::1")/UDP(chksum=0xf)/("X"*46),
Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IPv6(src="::1")/TCP(chksum=0xf)/("X"*46)],
iface="ens192f0",count=4,inter=0,verbose=False)
Then verify that the same number of packet are correctly received on the tester.
Inspect the pcap file from the packet capture and verify the checksums.
6.4. Test Case: Validate RX checksum valid flags on the receive packet¶
Setup the csum forwarding mode:
testpmd> set fwd csum
Set csum packet forwarding mode
Start the packet forwarding:
testpmd> port stop all
testpmd> csum set ip hw 0
testpmd> csum set udp hw 0
testpmd> csum set tcp hw 0
testpmd> csum set sctp hw 0
testpmd> port start all
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.
Send a packet ptypes is IP/UDP with a good checksum:
sendp(Ether(dst='23:00:00:00:00:00', src='52:00:00:00:00:00')/IP(chksum=int(0x7ca0))/UDP(chksum=int(0x1126))/('X'*50), iface=iface)

6.5. Test Case: Hardware Checksum Check L4 RX¶
This test involves testing many different scenarios with a L4 checksum.
A variety of tunneling protocols, L3 protocols and L4 protocols are combined
to test as many scenarios as possible. Currently, UDP, TCP and SCTP are used
as L4 protocols, with IP and IPv6 being used at level 3. The tested tunneling
protocols are VXLAN and GRE.
