[dpdk-dev] vmxnet3: set txq_flags in default TX conf

  Since commit fbde27f19ab8f "get default Rx/Tx configuration from dev info",
a default RX/TX configuration can be used for all PMDs.
In case of vmxnet3, the whole structure was zeroed and not filled out.
The PMD does not support multi segments or offload functions,
so txq_flags should have those flags set.

- Tested Commit: Pablo
- OS: Fedora20 3.15.8-200.fc20.x86_64
- GCC: gcc version 4.8.3 20140624
- CPU: Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
- NIC: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection [8086:10fb]
- Default x86_64-native-linuxapp-gcc configuration
- Total 6 cases, 6 passed, 0 failed
- Test Environment setup

- Topology #1: Create 2VMs (Fedora 20, 64bit);for each VM, pass through one physical port(Niantic 82599) to VM, and also create one virtual device: vmxnet3 in VM. Between two VMs, use one vswitch to connect 2 vmxnet3. In summary, PF1 
               and vmxnet3A are in VM1; PF2 and vmxnet3B are in VM2.The traffic flow for l2fwd/l3fwd is as below:                            
               Ixia -> PF1 -> vmxnet3A -> vswitch -> vmxnet3B -> PF2 -> Ixia. 
- Topology #2: Create 1VM (Fedora 20, 64bit), on this VM, created 2 vmxnet3, called vmxnet3A, vmxnet3B; create 2 vswitch, vswitchA connecting PF1 and vmxnet3A, while vswitchB connecting PF2 and vmxnet3B. The traffic flow is as below:
               Ixia -> PF1 -> vswitchA -> vmxnet3A -> vmxnet3B -> vswitchB -> PF2 -> Ixia.

- Test Case1: L2fwd with Topology#1 
  Description: Set up topology#1(in prerequisite session), and bind PF1, PF2, Vmxnet3A, vmxnet3B to DPDK poll-mode driver (igb_uio).
               Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see  
               if any unexpected behavior, such as no receives after N packets. 
  Command / instruction:
                To run the l2fwd example in 2VMs:
                                ./build/l2fwd -c f -n 4 -- -p 0x3
- Test IXIA Flow prerequisite: Ixia port1 sends 5 packets to PF1, and the flow should have PF1's MAC as destination MAC. Check if ixia port2 have received the 5 packets.
  Expected test result:
                Passed

- Test Case2: L3fwd-VF with Topology#1
  Description: Set up topology#1(in prerequisite session), and bind PF1, PF2, Vmxnet3A, vmxnet3B to DPDK poll-mode driver (igb_uio)
               Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see  
               if any unexpected behavior, such as no receives after N packets.
  Command / instruction:
                To run the l3fwd-vf example in 2VMs:
                                ./build/l3fwd-vf -c 0x6 -n 4 -- -p 0x3 --config "(0,0,1),(1,0,2)"
- Test IXIA Flow prerequisite: Ixia port1 sends 5 packets to PF1, and the flow should have PF1's MAC as destination MAC and have 2.1.1.x as destination IP. Check if ixia port2 have received the 5 packets.
  Expected test result:
                Passed

- Test Case3: L2fwd with Topology#2
  Description: Set up topology#2(in prerequisite session), and bind vmxnet3A and vmxnet3B to DPDK poll-mode driver (igb_uio).
               Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see  
               if any unexpected behavior, such as no receives after N packets.
  Command / instruction:

                                ./build/l2fwd -c f -n 4 -- -p 0x3
- Test IXIA Flow prerequisite: Ixia port1 sends 5 packets to port0 (vmxnet3A), and the flow should have port0's MAC as destination MAC. Check if ixia port2 have received the 5 packets. Similar things need to be done at ixia port2.
  Expected test result:
                Passed

- Test Case4: L3fwd-VF with Topology#2
  Description: Set up topology#2(in prerequisite session), and bind vmxnet3A and vmxnet3B to DPDK poll-mode driver (igb_uio).  
               Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see  
               if any unexpected behavior, such as no receives after N packets.

- Test IXIA Flow prerequisite: Ixia port1 sends 5 packets to port0(vmxnet3A), and the flow should have port0's MAC as destination MAC and have 2.1.1.x as destination IP. Check if ixia port2 have received the 5 packets.

  Expected test result:
                Passed
