- OS: Linux fc20 3.11.10-301.fc20.x86_64

- GCC: gcc version 4.8.3 20140624
- NIC:  Intel Corporation Ethernet Controller X710 for 10GbE SFP+ [8086:1572]

- Default x86_64-native-linuxapp-gcc configuration
- Total 1 cases, 1 passed, 0 failed

- Case: pmdrss_reta
  Description: pmdrss_reta 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.
  Command / instruction:
	#1. set up testpmd with fortville NICs::
  	./testpmd -c fffff -n %d -- -i --coremask=0xffffe --rxq=16 --txq=16

	#2. verbose configuration::
 	 testpmd command: set verbose 8
	#3. PMD fwd only receive the packets::
  	testpmd command: set fwd rxonly

	#4. Reta Configuration.  128 or 512 reta entries configuration::
  	testpmd command: port config 0 rss reta (hash_index,queue_id)
	#5. 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="", dst="")], iface="eth3")
  Expected 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. The theoretical queue id is the same with the actual queue id.

Subject: [dpdk-dev] [PATCH v5 0/8] support of multiple sizes of redirection table

As e1000, ixgbe and i40e hardware use different sizes of redirection table in PF or VF, ethdev and PMDs need to be reworked to support multiple sizes of that table. In addition, commands in testpmd also need to be reworked to support these changes.

v2 changes:
* Reorganized the patches.
* Added code style fixes.
* Added support of reta updating/querying in i40e VF.

v3 changes:
* Reorganized the patch set.
* Added returning default RX/TX configurations in VF (igb/ixgbe/i40e), as the
  patch set of it for PF has been accepted recently.

v4 changes:
* Added more comments to rte_eth_dev_rss_reta_update() and

v5 changes:
* Reworked the annotations of macros of RETA sizes in rte_ethdev.h.

Helin Zhang (8):
  app/testpmd: code style fix
  i40evf: code style fix
  i40e: support of setting hash lookup table size
  igb: implement ops of 'dev_infos_get' for PF and VF respectively
  ixgbe: implement ops of 'dev_infos_get' for PF and VF     respectively
  i40e: rework of ops of 'dev_infos_get' for both PF and VF
  ethdev: support of multiple sizes of redirection table
  i40evf: support of updating/querying redirection table
