- Prerequisites:
- Total 3 cases, 3 passed, 0 failed

- Prerequisites command / instruction:
1. Hardware:
   Fortville

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

    ./x86_64-native-linuxapp-gcc/app/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

- Cases:

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)

   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.

4. verified the rules can be listed and flushed::

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

Notes: fortville can't parse the TCP SYN type packet, fortpark can parse it.
So if fortville, pkt2 to queue 6 or queue 7.

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 0 queue_num 1
    testpmd> set port 0 queue-region region_id 7 queue_start_index 1 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::

    pkt1=Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/Dot1Q(prio=3)/IP(src="192.168.0.1", dst="192.168.0.2")/UDP(sport=22, dport=23)/Raw('x'*20)
    pkt2=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")/UDP(sport=22, dport=23)/Raw('x'*20)
    pkt3=Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/Dot1Q(prio=2)/IP(src="192.168.0.1", dst="192.168.0.2")/TCP(sport=32, dport=33)/Raw('x'*20)
    pkt4=Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/Dot1Q(prio=7)/IP(src="192.168.0.1", dst="192.168.0.2")/TCP(sport=32, dport=33)/Raw('x'*20)
    pkt5=Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/Dot1Q(prio=7)/IP(src="192.168.0.3", dst="192.168.0.4")/UDP(sport=22, dport=23)/Raw('x'*20)
    pkt6=Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/IP(src="192.168.0.3", dst="192.168.0.4")/UDP(sport=22, dport=23)/Raw('x'*20)

   verify the pkt1 to queue 0,
   pkt2 to queue 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8.
   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 enter different queue from pkt5.

4. verified the rules can be listed and flushed::

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

Test case 3: boundary value testing
===================================

1. boundary value testing of "Set a queue region on a port"

   the following three rules are set successfully::

    testpmd> set port 0 queue-region region_id 0 queue_start_index 0 queue_num 16
    testpmd> set port 0 queue-region flush on
    testpmd> set port 0 queue-region flush off
    testpmd> set port 0 queue-region region_id 0 queue_start_index 15 queue_num 1
    testpmd> set port 0 queue-region flush on
    testpmd> set port 0 queue-region flush off
    testpmd> set port 0 queue-region region_id 7 queue_start_index 2 queue_num 8
    testpmd> set port 0 queue-region flush on

   all the three rules can be listed::

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

   the following four rules can't be set successfully.::

    testpmd> set port 0 queue-region region_id 8 queue_start_index 2 queue_num 2

   no rules can be listed::

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

2. boundary value testing of "Set the mapping of flowtype to region index
   on a port"::

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

   the first two rules can be set successfully::

    testpmd> set port 0 queue-region region_id 0 flowtype 63
    testpmd> set port 0 queue-region region_id 7 flowtype 0

   the first two rules can be listed::

    testpmd> show port 0 queue-region

   the last two rule can't be set successfully::

    testpmd> set port 0 queue-region region_id 0 flowtype 64
    testpmd> set port 0 queue-region region_id 2 flowtype 34
    testpmd> set port 0 queue-region flush on

   the last two rules can't be listed::

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

3. boundary value testing of "Set the mapping of UP to region index
   on a port"::

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

   the first two rules can be set successfully::

    testpmd> set port 0 queue-region UP 7 region_id 0
    testpmd> set port 0 queue-region UP 0 region_id 7

   the first two rules can be listed::

    testpmd> show port 0 queue-region

   the last two rule can't be set successfully::

    testpmd> set port 0 queue-region UP 8 region_id 0
    testpmd> set port 0 queue-region UP 1 region_id 2
    testpmd> set port 0 queue-region flush on
