- Prerequisites:
- Total 1 cases, 1 passed, 0 failed

- Case:
./usertools/dpdk-devbind.py -b igb_uio 05:00.0 05:00.1 1. Start the testpmd::

    ./testpmd -c 1ffff -n 4 -- -i --nb-cores=8 --rxq=4 --txq=4 --port-topology=chained
    testpmd> set fwd rxonly
    testpmd> set verbose 1
    testpmd> start

2. Show port default RSS fuctions::

    testpmd> show port 0 rss-hash
    RSS functions:
     ipv4-frag ipv4-other ipv6-frag ipv6-other ip

   Send the ipv4-other packets with different src/dst ip address.
   All the packets are distributed to all the four queues.

3. disable all RSS fuctions::

    testpmd> flow create 0 ingress pattern end actions rss types none end / end
    Flow rule #0 created
    testpmd> show port 0 rss-hash
    RSS disabled

   Send the ipv4-udp packets with different src/dst ip address.
   All the packets are distributed to queue 0.
   Notes: only i40e support the command,
   others don't support the command created.

4. enable RSS fuction with all RSS hash type::

    testpmd> flow create 0 ingress pattern end actions rss types all end / end
    Flow rule #1 created
    testpmd> show port 0 rss-hash
    RSS functions:
     all ipv4-frag ipv4-tcp ipv4-udp ipv4-sctp ipv4-other ipv6-frag ipv6-tcp ipv6-udp ipv6-sctp ipv6-other l2-payload ip udp tcp sctp

   Send the ipv4-udp packets with different src/dst ip address.
   All the packets are distributed to all the four queues.

Subject: [PATCH] app/testpmd: support more types for flow RSS

Some user and tester require flow RSS to support more types, so and "all" and "none" to make configuration more easy for users.
