56. DDP L2TPV3

DDP profile 0x80000004 adds support for directing L2TPv3 packets based on their session ID for Intel® Ethernet 700 Series NIC. For DDP introduction, please refer to :

l2tpv3oip-l4.pkg defines and supports below pctype packets, also could check the information using command “ddp get info <profile>” after loading the profile. left numbers are pctype values,right are supported packets:

28: IPV4 L2TPV3
38: IPV6 L2TPV3

Packet Classifier types and Its Input Set

Packet Type PCType Hash Input Set FD Input Set
IPv4,L2TPv3 28 L2TPv3 Session ID L2TPv3 Session ID
IPv6,L2TPv3 38 L2TPv3 Session ID L2TPv3 Session ID

56.1. Requirements as below

Flow API support for flow director rules based on L2TPv3 session ID The current scope is limited to Intel® Ethernet 700 Series NIC

56.2. Prerequisites

  1. DPDK version 20.02 or greater

  2. I40E NIC with FW version 6.0 or greater

    In your linux terminal enter ethtool -i <interface-name> , this prints out the driver details. Ex

    root@hostname:~/dpdk# ethtool -i <interface-name>
driver: i40e
version: 2.1.14-k
firmware-version: 7.10 0x80006474 1.2527.0
expansion-rom-version:
bus-info: 0000:02:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

Note: If the firmware version is below 6.0 , the NIC does not support any DDP functionality

  1. Download and extract L2TPv3 package

    https://downloadcenter.intel.com/download/28941/Dynamic-Device-Personalization-L2TPv3

  2. Bind the Port to the userspace Driver <igb_uio/vfio-pci):

    ./usertools/dpdk-devbind.py -b <igb_uio/vfio-pci> <PCI address of device to bind>

  3. Start the TESTPMD:

    ./<build>/app/dpdk-testpmd -c f -n 4 -a
<PCI address of device> -- -i --port-topology=chained --txq=64 --rxq=64

    For testpmd commands refer: https://doc.dpdk.org/guides/testpmd_app_ug/

  4. Set Verbose

    To enable verbose logging in the testpmd application to get detailed information about rx queues and packet metadata:

    testpmd > set verbose 1

  5. To enable required fields as per the indices in the L2TPv3 Packet field vector (refer Dynamic_Device_Personalization_L2TPv3_Rev1.x)

    To enable the specific field in the vector for a PCTYPE , the following command may be used:

    testpmd> port config <port_id> pctype <PCTYPE> fdir_inset set field
<field_index>

    To check if a specific field in the vector is set for a PCTYPE, the following command may be used:

    testpmd> port config <port_id> pctype <PCTYPE> fdir_inset get field
<field_index>

    To clear any specific field in the vector for a PCTYPE, the following command may be used:

    testpmd> port config <port_id> pctype  <pctype> fdir_inset clear field
<field_index>

    To clear all fields for a specific PCTYPE, the following commands may be used:

    testpmd> port config <port_id> pctype <PCTYPE> fdir_inset clear all

NOTE: Changes such as enabling/disabling of specific field in the vector for a PCTYPE will remain applied across restarts of testpmd application. It is good practice to explicitly set the desired field in the vector for a PCTYPE upon start of testpmd.

56.3. Test Case : Adding L2TPv3 profile to the port

  1. Stop testpmd port before loading profile:

    testpmd > port stop <port_id>

  2. Load l2tpv3oip-l4.pkg file to the memory buffer and save the existing configuration to the l2tpv3oip-l4.bak file:

    testpmd > ddp add <port_id> <path>/l2tpv3oip-l4.pkg,<path>/
l2tpv3oip-l4.bak

  3. Check to see if the profile is loaded

    testpmd> ddp get list <port_id>
Track id:     0x80000004
Version:      1.0.0.0
Profile name: L2TPv3oIP with L4 payload

56.4. Test Case : Deleting L2TPv3 profile from the port

This test is intended to revert to the original DDP profile of the port without reset

  1. Stop testpmd port before loading profile:

    testpmd > port stop <port_id>

  2. Remove profile from the network adapter and restore original configuration:

    testpmd > ddp del <port_id> <path>/l2tpv3oip-l4.bak

  3. Check to see if the profile is deleted:

    testpmd> ddp get list <port_id>
Profile number is: 0

56.5. Test Case : Adding and deleting Flow Director rules

  1. To Add l2tpv3 flow director rules:

    testpmd> flow create <port_id> ingress pattern eth / ipv4 / l2tpv3oip session_id
is 1 / end actions queue index 1 / end
testpmd> flow create <port_id> ingress pattern eth / ipv4 / l2tpv3oip session_id
is 2 / end actions queue index 2 / end
testpmd> flow create <port_id> ingress pattern eth / ipv4 / l2tpv3oip session_id
is 3 / end actions queue index 3 / end

  2. To List the rules using the flow list command with port number:

    testpmd> flow list <port_id>
   ID      Group   Prio    Attr    Rule
   0       0       0       i--     ETH IPV4 L2TPV3 => QUEUE
   1       0       0       i--     ETH IPV4 L2TPV3 => QUEUE
   2       0       0       i--     ETH IPV4 L2TPV3 => QUEUE

  3. To delete a single rule

    testpmd> flow destroy <port_id> rule 0
Flow rule #0 destroyed
testpmd> flow list <port_id>
   ID      Group   Prio    Attr    Rule
   1       0       0       i--     ETH IPV4 L2TPV3 => QUEUE
   2       0       0       i--     ETH IPV4 L2TPV3 => QUEUE
  <flow rule with ID 0 should not be listed>

  4. To delete all the rules:

    testpmd> flow flush <port_id>
testpmd> flow list <port_id>
testpmd>
(No List is printed)
