35. ICE IAVF IP FRAGMENT RTE FLOW TEST

35.1. Description

This document provides the plan for testing ip fragment.

DPDK-21.05 enable ipv4/6 fragment in rte_flow by IPID on Intel E810 series ethernet cards, major feature are:

• IP fragment packet can be filtered by IPID with RTE_FLOW in FDIR:

  queue index
  drop
  rss queues
  passthru
  mark
  mark/rss
  

• IP fragment packet is based on 5-tuple(src-ip/dst-ip/src-port/dst-port/l3 protocol) + IPID as inputset to get hash value in RSS

• It’s enable on both PF and VF, this plan test on VF.

Note

Currently, ipv4/6 fragment packet was treated as “IPv4/6 pay”, so only validate ipv4/6 fragment pattern.

35.2. Prerequisites

1. Hardware: Intel® Ethernet 800 Series: E810-XXVDA4/E810-CQ

2. Software: dpdk: http://dpdk.org/git/dpdk

   scapy: http://www.secdev.org/projects/scapy/

3. Get the pci device id of DUT, for example:

   ./usertools/dpdk-devbind.py -s
   
   0000:18:00.0 'Device 1593' if=enp24s0f0 drv=ice unused=vfio-pci
   0000:18:00.1 'Device 1593' if=enp24s0f1 drv=ice unused=vfio-pci
   

4. create vf and bind to dpdk:

   echo 1 > /sys/bus/pci/devices/0000:18:00.0/sriov_numvfs
   ip link set ens801f0 vf 0 mac 00:11:22:33:55:66
   
   ./usertools/dpdk-devbind.py -s
   0000:18:01.0 'Ethernet Adaptive Virtual Function 1889' if=enp24s1 drv=iavf unused=vfio-pci
   
   Bind VFs to dpdk driver:
   modprobe vfio-pci
   ./usertools/dpdk-devbind.py -b vfio-pci 0000:18:01.0 0000:18:01.1
   

5. Launch testpmd:

   fdir testpmd command:
   ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -- -i --rxq=16 --txq=16
   
   rss testpmd command:
   ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -- -i --rxq=16 --txq=16 --disable-rss --rxd=384 --txd=384
   
   testpmd> set fwd rxonly
   testpmd> set verbose 1
   testpmd> start
   

35.3. Basic Test Steps

The steps same as FDIR/RSS suites test steps

35.3.1. take ‘MAC_IPV4_FRAG fdir queue index’ for fdir example

Note

The default rss not support ipfragment, need take a rss rule to enable ipfragment rss.

1. validate and create rule:

   take a ipfragment rss rule:
   flow create 0 ingress pattern eth / ipv4 / end actions rss types eth ipv4-frag end key_len 0 queues end / end
   
   take fdir rule:
   
   flow validate 0 ingress pattern eth / ipv4 fragment_offset spec 0x2000 fragment_offset mask 0x2000 / end actions queue index 1 / mark / end
   Flow rule validated
   flow create 0 ingress pattern eth / ipv4 fragment_offset spec 0x2000 fragment_offset mask 0x2000 / end actions queue index 1 / mark / end
   Flow rule #0 created
   

Note

For ipfragment rule, it’s a fixed combination for parser to know that a fragment pkt. dpdk care about the bit 12-13 of fragment offset, so the valid range is 0x2000-0x1fff, the spec is 0x2000 and mask is 0x2000.

2. send matched pkts and check two pkts distributed to queue 1, RSS hash=0x261a7deb - RSS queue=0x1 in output:

   scapy:
   p = Ether()/IP(id=47750)/Raw('X'*666)
   pkts=fragment(p, fragsize=500)
   sendp(pkts, iface="enp1s0")
