45. DDP PPPoE/L2TPv2/PPPoL2TPv2

Fortville supports PPPoE/L2TPv2/PPPoL2TPv2 new protocols after loading profile. For DDP introduction, please refer to ddp gtp or ddp mpls test plan.

Requirements as below:

- RSS for PPPoE packets: without IP payload, using session id and source
  MAC as hash input set. With IP payload, using IP addresses and L4 ports
  as hash input set.

- Classification for non-multicast IP encapsulated to PPPoL2TP: using
  inner 5-tuple as hash input set for RSS.

- Classification for multicast IP encapsulated to PPPoL2TP: assign
  packets to specific queue according to inner dst IP address.

Dynamic flow type mapping eliminates usage of number of hard-coded flow types in bulky if-else statements. For instance, when configure hash enable flags for RSS in i40e_config_hena() function and will make partitioning FVL in i40e PMD more scalable.

I40e PCTYPEs are statically mapped to RTE_ETH_FLOW_* types in DPDK, defined in rte_eth_ctrl.h, flow types used to define ETH_RSS_* offload types in rte_ethdev.h. RTE_ETH_FLOW_MAX is defined now as 22, leaves 42 flow type unassigned.

Ppp-oe-ol2tpv2.pkgo 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:

14: L2TPv2CTRL
15: PPPoE IPV4
16: PPPoE IPV6
17: PPPoE
18: PPPoL2TPv2 IPV4
19: PPPoL2TPv2 IPV6
20: PPPoL2TPv2
21: L2TPv2PAY

There are so many kinds of packets that we can’t cover all pctype test scenarios, below test plan focuses on above requirements to illustrate usage, also could do similar test for other packets. Select flow types value between 23 and 63, design pctype, flow type and default input set mapping as below:

45.1. Prerequisites

  1. Host PF in DPDK driver:

    ./tools/dpdk-devbind.py -b igb_uio 81:00.0
    
  2. Start testpmd on host, set chained port topology mode, add txq/rxq to enable multi-queues. If test PF flow director, need to add –pkt-filter-mode=perfect on testpmd to enable flow director. In general, PF’s max queue is 64:

    ./testpmd -c f -n 4 -- -i --port-topology=chained --txq=64 --rxq=64
    --pkt-filter-mode=perfect
    

45.2. Load/delete dynamic device personalization

  1. Stop testpmd port before loading profile:

    testpmd > port stop all
    
  2. Load ppp-oe-ol2tpv2.pkgo file to the memory buffer, save original configuration and return in the same buffer to the ppp-oe-ol2tpv2.bak file:

    testpmd > ddp add (port_id) /tmp/ppp-oe-ol2tpv2.pkgo,
    /tmp/ppp-oe-ol2tpv2.bak
    
  3. Remove profile from the network adapter and restore original configuration:

    testpmd > ddp del (port_id) /tmp/ppp-oe-ol2tpv2.bak
    
  4. Start testpmd port:

    testpmd > port start all
    

45.3. Note

Ppp-oe-ol2tpv2.pkgo profile has been released publicly. You could download below version to do our regression relative test. Loading DDP profile is the prerequisite for below RSS and flow director cases:

  4. Inner dst IP words are 27 and 28, enable flow director input set for them:

    testpmd> port config 0 pctype 18 fdir_inset set field 27
    testpmd> port config 0 pctype 18 fdir_inset set field 28
    
  5. Start testpmd, set fwd rxonly, enable output print

  6. Send PPPoL2TP IPv4 packets, check to receive packet from queue 0:

    p=Ether()/IP()/UDP(dport=1701, sport=1701)/PPP_L2TP(proto=0x0021)/
    IP(src="1.1.1.1",dst="2.2.2.2")/UDP(sport=4000, dport=8000)/Raw('x' * 20)
    
  7. Use scapy to generate PPPoL2TP IPv4 raw packet test_pppol2tp.raw, source/destination address and port should be swapped in the template and traffic packets:

    a=Ether()/IP()/UDP(dport=1701, sport=1701)/PPP_L2TP(proto=0x0021)/
    IP(dst="1.1.1.1",src="2.2.2.2")/UDP(dport=4000, sport=8000)/Raw('x' * 20)
    
  8. Setup raw flow type filter for flow director, configured queue is random queue between 0~63, such as 36:

    testpmd> flow_director_filter 0 mode raw add flow 23 fwd queue 36
    fd_id 1 packet test_pppol2tp.raw
    
  9. Send matched swapped traffic packet, check to receive packet from configured queue 36:

    p=Ether()/IP()/UDP(dport=1701, sport=1701)/PPP_L2TP(proto=0x0021)/
    IP(src="1.1.1.1",dst="2.2.2.2")/UDP(sport=4000, dport=8000)/Raw('x' * 20)
    
  10. Send matched inner dst IP, but non-matched inner src IP, sport, dport packets, check to receive packet from queue 36:

    p=Ether()/IP()/UDP(dport=1701, sport=1701)/PPP_L2TP(proto=0x0021)/
    IP(src="1.1.1.2",dst="2.2.2.2")/UDP(sport=4000, dport=8000)/Raw('x' * 20)
    p=Ether()/IP()/UDP(dport=1701, sport=1701)/PPP_L2TP(proto=0x0021)/
    IP(src="1.1.1.1",dst="2.2.2.2")/UDP(sport=4001, dport=8000)/Raw('x' * 20)
    p=Ether()/IP()/UDP(dport=1701, sport=1701)/PPP_L2TP(proto=0x0021)/
    IP(src="1.1.1.1",dst="2.2.2.2")/UDP(sport=4000, dport=8001)/Raw('x' * 20)
    
  11. Send non-matched inner dst IP packets, check to receive packet from queue 0:

    p=Ether()/IP()/UDP(dport=1701, sport=1701)/PPP_L2TP(proto=0x0021)/
    IP(src="1.1.1.1",dst="2.2.2.3")/UDP(sport=4000, dport=8000)/Raw('x' * 20)
    

45.21. Test Case: Flow director for PPPoL2TP IPv6 according to inner destination IPv6

  1. Check flow type to pctype mapping:

    testpmd> show port 0 pctype mapping
    
  2. Update PPPoL2TP IPv6 flow type id 24 to pcytpe id 19 mapping item:

    testpmd> port config 0 pctype mapping update 19 24
    
  3. Reset PPPoL2TP IPv6 flow director input set configuration:

    testpmd> port config 0 pctype 19 fdir_inset clear all
    
  4. Inner dst IPv6 words are 21~28, enable flow director input set for them:

    testpmd> port config 0 pctype 19 fdir_inset set field 21
    testpmd> port config 0 pctype 19 fdir_inset set field 22
    testpmd> port config 0 pctype 19 fdir_inset set field 23
    testpmd> port config 0 pctype 19 fdir_inset set field 24
    testpmd> port config 0 pctype 19 fdir_inset set field 25
    testpmd> port config 0 pctype 19 fdir_inset set field 26
    testpmd> port config 0 pctype 19 fdir_inset set field 27
    testpmd> port config 0 pctype 19 fdir_inset set field 28
    
  5. Start testpmd, set fwd rxonly, enable output print

  6. Send PPPoL2TP IPv6 packets, check to receive packet from queue 0:
