134. Intel® Ethernet 700 Series Configure RSS Queue Regions Tests

134.1. Description

Intel® Ethernet 700 Series/X722 series and future Intel® Ethernet 800 Series/E822 NICs support queue regions configuration for RSS in PF/VF, so different traffic classes or different packet classification types can be separated to different queue regions which includes several queues, but traffic classes and packet classification cannot co-existing with the support of queue region functionality. Different PCtype packets take rss algorithm in different queue regions.

Examples:

  • all TCP packets with SYN flags set can be sent to queue A, when TCP packets with out SYN flags will be distributed to queues B-F.
  • IPv4 and IPv6 packets distributed to different queue regions
  • UDP and TCP packets distributed to different queue regions
  • Different tunnels distributed to different queue regions (requires tunnels PCTYPEs creation using personalization profiles)
  • different traffic classes defined in VLAN PCP bits distributed to different queue regions

For Intel® Ethernet 700 Series see chapter 7.1.7 of the latest datasheet. For X722 series/E822 see corresponding EAS sections.

134.2. Prerequisites

  1. Hardware: Intel® Ethernet 700 Series

  2. software: dpdk: http://dpdk.org/git/dpdk scapy: http://www.secdev.org/projects/scapy/

  3. bind the port to dpdk driver:

    ./usertools/dpdk-devbind.py -b igb_uio 05:00.0

    the mac address of 05:00.0 is 00:00:00:00:01:00

  4. start the testpmd:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 1ffff -n 4 -- -i --rxq=16 --txq=16
testpmd> port config all rss all
testpmd> set fwd rxonly
testpmd> set verbose 1
testpmd> start

134.3. Test case 1: different pctype packet can enter the expected queue region

  1. Set queue region on a port:

    testpmd> set port 0 queue-region region_id 0 queue_start_index 1 queue_num 1
testpmd> set port 0 queue-region region_id 1 queue_start_index 3 queue_num 2
testpmd> set port 0 queue-region region_id 2 queue_start_index 6 queue_num 2
testpmd> set port 0 queue-region region_id 3 queue_start_index 8 queue_num 2
testpmd> set port 0 queue-region region_id 4 queue_start_index 11 queue_num 4
testpmd> set port 0 queue-region region_id 5 queue_start_index 15 queue_num 1

  2. Set the mapping of flowtype to region index on a port:

    testpmd> set port 0 queue-region region_id 0 flowtype 31
testpmd> set port 0 queue-region region_id 1 flowtype 32
testpmd> set port 0 queue-region region_id 2 flowtype 33
testpmd> set port 0 queue-region region_id 3 flowtype 34
testpmd> set port 0 queue-region region_id 4 flowtype 35
testpmd> set port 0 queue-region region_id 5 flowtype 45
testpmd> set port 0 queue-region region_id 2 flowtype 41
testpmd> set port 0 queue-region flush on

  3. send packet:

    pkt1 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IP(src="192.168.0.1", dst="192.168.0.2")/UDP(sport=23,dport=24)/Raw('x'*20)
pkt2 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IP(src="192.168.0.1", dst="192.168.0.2")/TCP(sport=33,dport=34,flags="S")/Raw('x'*20)
pkt3 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IP(src="192.168.0.1", dst="192.168.0.2")/TCP(sport=33,dport=34,flags="PA")/Raw('x' * 20)
pkt4 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IP(src="192.168.0.1", dst="192.168.0.2")/SCTP(sport=44,dport=45,tag=1)/SCTPChunkData(data="X" * 20)
pkt5 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IP(src="192.168.0.1", dst="192.168.0.2")/Raw('x'*20)
pkt6 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IPv6(src="2001::1", dst="2001::2")/Raw('x' * 20)
pkt7 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IPv6(src="2001::1", dst="2001::2")/UDP(sport=24,dport=25)/Raw('x'*20)
pkt8 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/Dot1Q(prio=1)/IP(src="192.168.0.1", dst="192.168.0.2")/Raw('x'*20)
pkt9 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IPv6(src="2001::1", dst="2001::2")/TCP(sport=24,dport=25)/Raw('x'*20)

    verify the pkt1 to queue 1, pkt2 to queue 3 or queue 4, pkt3 to queue 6 or queue 7, pkt4 to queue 8 or queue 9, pkt5 to queue 11 or 12 or 13 or 14, pkt6 to queue 15, pkt7 to queue 6 or queue 7, pkt8 enter the same queue with pkt5. pkt9 to queue 1.

    Notes: If the packet type doesn’t match any queue region rules, it will be distributed to the queue of queue region 0, despite queue region 0 matches any rule.

  4. verified the rules can be listed and flushed:

    testpmd> show port 0 queue-region
testpmd> set port 0 queue-region flush off

    Send the pkt1-pkt9, the packets can’t enter the same queue which defined in queue region rule. They are distributed to queues according RSS rule.

Notes: Intel® Ethernet 700 Series can’t parse the TCP SYN type packet, X722 series can parse it. So if Intel® Ethernet 700 Series, pkt2 to queue 6 or queue 7.

134.4. Test case 2: different user priority packet can enter the expected queue region

  1. Set queue region on a port:

    testpmd> set port 0 queue-region region_id 0 queue_start_index 14 queue_num 2
testpmd> set port 0 queue-region region_id 7 queue_start_index 0 queue_num 8
testpmd> set port 0 queue-region region_id 2 queue_start_index 10 queue_num 4

  2. Set the mapping of User Priority to Traffic Classes on a port:

    testpmd> set port 0 queue-region UP 3 region_id 0
testpmd> set port 0 queue-region UP 1 region_id 7
testpmd> set port 0 queue-region UP 2 region_id 2
testpmd> set port 0 queue-region UP 7 region_id 2
testpmd> set port 0 queue-region flush on

  3. send packet:

    verify the pkt1 to queue 14 or 15, pkt2 to queue 0 or 1 or 2 or 3 or 4 or 5 or 6 or 7. pkt3 to queue 10 or 11 or 12 or 13. pkt4 enter the same queue with pkt3. pkt5 to queue 10 or 11 or 12 or 13. pkt6 to queue 14 or 15.

    Notes: If the packet UP doesn’t match any queue region rules, it will be distributed to the queue of queue region 0, despite queue region 0 matches any rule.

  4. verified the rules can be listed and flushed:

    testpmd> show port 0 queue-region
testpmd> set port 0 queue-region flush off

    Send the pkt1-pkt6, the packets can’t enter the same queue which defined in queue region rule. They are distributed to queues according RSS rule.
