+Fortville - support granularity configuration of RSS, support 32-bit 
+GRE keys 
+==================================================================
+
+Description
+===========
+This document provides test plan for testing the function of Fortville:
+
+1. Support granularity configuration of RSS
+
+By default Fortville uses hash input set preloaded from NVM image which 
+includes all fields
+- IPv4/v6+TCP/UDP port. Potential problem for this is global 
+configuration per device and can affect all ports. It is required that 
+hash input set can be configurable,  such as using IPv4 only or IPv6 only or IPv4/v6+TCP/UDP.
+
+2. support 32-bit GRE keys
+
+By default Fortville extracts only 24 bits of GRE key to FieldVector 
+(NVGRE use case) but for Telco use cases full 32-bit GRE key is needed. 
+It is required that both 24-bit and 32-bit keys for GRE should be 
+supported. the test plan is to test the API to switch between 24-bit 
+and 32-bit keys
+
+
+Prerequisites
+-------------
+
+1. Hardware:
+  1x Fortville_eagle NIC (4x 10G)
+  1x Fortville_spirit NIC (2x 40G)
+  2x Fortville_spirit_single NIC (1x 40G)
+
+2. software: 
+  dpdk: http://dpdk.org/git/dpdk
+  scapy: http://www.secdev.org/projects/scapy/
+
+
+Test Case 1: test with flow type ipv4-tcp 
+===============================
+
+1. config testpmd on DUT
+
+1). set up testpmd with fortville NICs::
+  ./testpmd -c 0x1ffff -n 4 -- -i --coremask=0x1fffe --portmask=0x3  
+--rxq=16 --txq=16 --txqflags=0
+
+2). Reta Configuration(optional, if not set, will use default)::
+  testpmd> port config 0 rss reta (hash_index,queue_id)
+
+3). PMD fwd only receive the packets::
+  testpmd> set fwd rxonly
+  
+4). rss recived package type configuration::
+  testpmd> port config all rss tcp
+
+5). set hash function::  
+  testpmd>set_hash_global_config 0 toeplitz ipv4-tcp enable
+
+6). verbose configuration::
+  testpmd> set verbose 8
+
+7). start packet receive::
+  testpmd> start
+  
+2. using scapy to send packets with ipv4-tcp on tester,
+  
+  sendp([Ether(dst="%s")/IP(src="192.168.0.%d", 
+ dst="192.168.0.%d")/TCP(sport=1024,dport=1025)], iface="%s")
+  
+then got hash value and queue value that output from the testpmd on DUT. 
+
+3. set hash input set to "none" by testpmd on dut,
+
+testpmd> set_hash_input_set 0 ipv4-tcp none select
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be different from the values in step 2.
+
+4. set hash input set by testpmd on dut, enable src-ipv4 & dst-ipv4,
+
+testpmd> set_hash_input_set 0 ipv4-tcp src-ipv4 add set_hash_input_set 
+testpmd> 0 ipv4-tcp dst-ipv4 add
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be different from the values in step 2.
+
+5. set hash input set by testpmd on dut, enable src-ipv4, dst-ipv4, 
+tcp-src-port, tcp-dst-port
+
+testpmd> set_hash_input_set 0 ipv4-tcp tcp-src-port add 
+testpmd> set_hash_input_set 0 ipv4-tcp tcp-dst-port add
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be should be different with the values from step 3 & step 4, should be same as step 2.
+
+6. set hash input set by testpmd on dut, enable tcp-src-port, 
+tcp-dst-port
+
+testpmd> set_hash_input_set 0 ipv4-tcp none select set_hash_input_set 0 
+testpmd> ipv4-tcp tcp-src-port add set_hash_input_set 0 ipv4-tcp 
+testpmd> tcp-dst-port add
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be should be different with the values from step2 & step 3 & step 4 & step 5.
+
+So it can be approved that with flow type ipv4-tcp, rss hash can be 
+calculated by only included IPv4 fields or only included TCP fields or both IPv4+TCP fields.
+
+
+Test Case 2: test with flow type ipv4-udp 
+=========================================
+
+1. config testpmd on DUT
+
+1). set up testpmd with fortville NICs::

+--rxq=16 --txq=16 --txqflags=0
+
+2). Reta Configuration(optional, if not set, will use default)::
+  testpmd> port config 0 rss reta (hash_index,queue_id)
+
+3). PMD fwd only receive the packets::
+  testpmd> set fwd rxonly
+  
+4). rss recived package type configuration::
+  testpmd> port config all rss udp
+
+5). set hash function::  
+  testpmd>set_hash_global_config 0 toeplitz ipv4-udp enable
+
+6). verbose configuration::
+  testpmd> set verbose 8
+
+7). start packet receive::
+  testpmd> start
+  
+2. using scapy to send packets with ipv4-udp on tester::
+  
+  sendp([Ether(dst="%s")/IP(src="192.168.0.%d", 
+ dst="192.168.0.%d")/UDP(sport=1024,dport=1025)], iface="%s"))
+  
+then got hash value and queue value that output from the testpmd on DUT. 
+
+3. set hash input set to "none" by testpmd on dut,
+
+testpmd> set_hash_input_set 0 ipv4-udp none select
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be different from the values in step 2.
+
+4. set hash input set by testpmd on dut, enable src-ipv4 and dst-ipv4,
+
+testpmd> set_hash_input_set 0 ipv4-udp src-ipv4 add set_hash_input_set 
+testpmd> 0 ipv4-udp dst-ipv4 add
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be different from the values in step 2 & step 3.
+
+5. set hash input set by testpmd on dut, enable src-ipv4, dst-ipv4, 
+udp-src-port, udp-dst-port
+
+testpmd> set_hash_input_set 0 ipv4-udp udp-src-port add 
+testpmd> set_hash_input_set 0 ipv4-udp udp-dst-port add
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be should be different with the values from step 3 & step 4, should be same as step 2.
+
+6. set hash input set by testpmd on dut, enable udp-src-port, 
+udp-dst-port

+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be should be different with the values from step2 & step 3 & step 4 & step 5.
+
+So it can be approved that with flow type ipv4-udp, rss hash can be 
+calculated by only included IPv4 fields or only included UDP fields or both IPv4+UDP fields.
+
+Test Case 3: test with flow type ipv6-tcp 
+=========================================

+Test Case 6: 32-bit GRE keys and 24-bit GRE keys test 
+=====================================================
+
+1. config testpmd on DUT
+
+1). set up testpmd with fortville NICs::

+  testpmd> port config all rss all
+
+5). set hash function::  
+  testpmd>set_hash_global_config 0 toeplitz ipv4-other enable
+
+6). verbose configuration::

+
+2. using scapy to send packets with GRE header on tester::
+  
+  
+ sendp([Ether(dst="%s")/IP(src="192.168.0.1",dst="192.168.0.2",proto=47
+ )/GRE(key_present=1,proto=2048,key=67108863)/IP()], iface="%s")
+ 
+then got hash value and queue value that output from the testpmd on DUT.
+
+3. set hash input set to "none" by testpmd on dut,
+
+testpmd> set_hash_input_set 0 ipv4-other none select
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the value shoud be different with the values in step 2.
+
+4. set hash input set by testpmd on dut, enable src-ipv4, dst-ipv4
+
+testpmd> set_hash_input_set 0 ipv4-other src-ipv4 add 
+testpmd> set_hash_input_set 0 ipv4-other dst-ipv4 add
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the value shoud be same with the values in step 2.
+
+4. set hash input set and gre-key-len=3 by testpmd on dut, enable 
+gre-key
+
+testpmd> global_config 0 gre-key-len 3
+testpmd> set_hash_input_set 0 ipv4-other gre-key add

+the testpmd on DUT, the values shoud be different with the values in step 2.
+
+5. set gre-key-len=4 by testpmd on dut, enable gre-key
+
+testpmd> global_config 0 gre-key-len 4
+
+send packet as step 2, got hash value and queue value that output from 
+the testpmd on DUT, the values shoud be different with the values in step 4.
+
+So with gre-key-len=3 (24bit gre key) or gre-key-len=4 (32bit gre key), 
+different rss hash value and queue value can be got, it can be proved that 32bit & 24bit gre key are supported by fortville.
