This patch has been verified on three kinds of Fortville NICs.

Base commit: 23fcffe8ffaccf8a2901050e7daa4979597141ed
CPU: Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
OS: Linux fc20 3.11.10-301.fc20.x86_64
GCC: 4.8.2
NIC: 4*10G(fortville_eagle), 2*40G(fortville_spirit), 1*40G(fortville_spirit_single)

==================================================================
Fortville RSS full support - Support configuring hash functions
==================================================================
This document provides test plan for testing the function of Fortville:
Support configuring hash functions.

Prerequisites
-------------
2x Intel(r) 82599 (Niantic) NICs (2x 10GbE full duplex optical ports per NIC)
1x Fortville_eagle NIC (4x 10G)
1x Fortville_spirit NIC (2x 40G)
2x Fortville_spirit_single NIC (1x 40G)

The four ports of the 82599 connect to the Fortville_eagle;
The two ports of Fortville_spirit connect to Fortville_spirit_single.
The three kinds of NICs are the target NICs. the connected NICs can send packets
to these three NICs using scapy.

Network Traffic
---------------
The RSS feature is designed to improve networking performance by load balancing
the packets received from a NIC port to multiple NIC RX queues, with each queue
handled by a different logical core.

#1. The receive packet is parsed into the header fields used by the hash
operation (such as IP addresses, TCP port, etc.)

#2. A hash calculation is performed. The Fortville  supports four hash function:
Toeplitz, simple XOR and their Symmetric RSS.

#3. The seven LSBs of the hash result are used as an index into a 128/512 entry
'redirection table'. Each entry provides a 4-bit RSS output index.

#4. There are four cases to test the four hash function.

Test Case:  test_toeplitz
=========================

Testpmd configuration - 16 RX/TX queues per port
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#1. set up testpmd with fortville NICs::
  ./testpmd -c fffff -n %d -- -i --coremask=0xffffe --rxq=16 --txq=16

#2. Reta Configuration.  128 reta entries configuration::
  testpmd command: port config 0 rss reta (hash_index,queue_id)

#3. PMD fwd only receive the packets::
  testpmd command: set fwd rxonly

#4. rss received package type configuration two received packet types configuration::
  testpmd command: port config 0 rss ip/udp

#5. verbose configuration::
  testpmd command: set verbose 8

#6. set hash functions, can choose symmetric or not, chose port and packet type::
  set_hash_function 0 toeplitz

#7. start packet receive::
  testpmd command: start

tester Configuration
--------------------

#1. set up scapy

#2. send packets with different type ipv4/ipv4 with tcp/ipv4 with udp/
    ipv6/ipv6 with tcp/ipv6 with udp::
    sendp([Ether(dst="90:e2:ba:36:99:3c")/IP(src="192.168.0.4", dst="192.168.0.5")], iface="eth3")

test result
-----------
The testpmd will print the hash value and actual queue of every packet.

#1. Calaute the queue id: hash value%128or512, then refer to the redirection table
    to get the theoretical queue id.

#2. Compare the theoretical queue id with the actual queue id. 

Test Case:  test_toeplitz_symmetric
===================================
The same with the above steps, pay attention to "set hash function", should use::
  set_hash_function 0 toeplitz
  set_sym_hash_ena_per_port 0 enable
  set_sym_hash_ena_per_pctype 0 35 enable

And send packets with the same flow in different direction::
  sendp([Ether(dst="90:e2:ba:36:99:3c")/IP(src="192.168.0.4", dst="192.168.0.5")], iface="eth3")
  sendp([Ether(dst="90:e2:ba:36:99:3c")/IP(src="192.168.0.5", dst="192.168.0.4")], iface="eth3")

And the hash value and queue should be the same for these two flow .

Test Case:  test_simple
=======================
The same as the above two test cases. Just pay attention to set the hash function to "simple xor"

Test Case:  test_simple_symmetric
=================================
The same as the above two test cases. Just pay attention to set the hash function to "simple xor"
