Traffic can be captured also at DUT side. Two options are supported by
vsperf:
1) Traffic is captured inside VM after it has been processed
by vSwitch. This can be used for verification of vSwitch frame
modification functionality, including HW offloading at ingress side.
2) Another NIC under the test (NIC2) is added into standard VSPERF DUT
setup. Traffic is then forwarded from TGen through NIC and vSwitch
to NIC2 and then over patch cable back to NIC2, the vSwitch, NIC and
to the traffic generator. This setup supports also verification of HW
offloading at egress side of NIC2 and thus it can be used for validation
of smart NICS.
Both options above are traffic generator agnostic if compared to direct
support of traffic capture by traffic generator. This patch introduces
example testcases for both options.
Detailed documentation will be pushed as a standalone patch.

This patch introduces several improvements and small bugfixes
of teststeps. These changes were identified during implementation
of OVS/DPDK regression tests.
Patch content:
* teststeps: step aliases were implemented
* teststeps: improved filtering by regex for any step, which returns string
or list of stings; filter will process all lines
* teststeps: support for log object
* teststeps: support for trafficgen get_results call
* teststeps: configurable suppression of step validation
* trafficgen: remove old results before traffic is executed
* trafficgen: support for flow control on/off (IxNet)
* trafficgen: support for configurable learning frames (IxNet)
* trafficgen: support for runtime changes of TRAFFICGEN_PKT_SIZES, _DURATION
and _LOSSRATE
* vnf: flush pexpect output of previous commands
* vnf: use execute_and_wait() to ensure correct cmds order
* vnf: dpdk vHost User interface name set according to its type,
e.g. dpdkvhostuserclient
* vswitch: support for OVS restart
* decap: simplify configuration of tunneling decapsulation tests
* settings: values of all configuration options are restored after TC execution
* modified formatting of test description used by --list
* testcase name and description is logged before its execution
* small bugfixes

A set of improvements was introduced to enhance step driven
testcases capabilities.
Details:
* delay among test steps is configurable by TEST_STEP_DELAY
parameter
* step driven tool function exec was renamed to exec_shell
* new step driven tool function exec_python was introduced to execute
a python code
* new step driven object sleep was introduced to pause test execution
for defined number of seconds.
* fixed bug in settings.validate_getValue() to correctly validate
access of parameters modified by TEST_PARAMS
* new #PARAM() macro was introduced to allow references among
configuration parameters
* multistream support has been added into ixnetrfc2544v2.tcl,
which is used for tunneling protocols test (op2p deployment)
* fixed bug in op2p deployment to list interfaces and flows
from both bridges involved in the test
* test report updated to state exact rfcxxxx type of traffic
type, e.g. rfc2544_continuous
* test report of step driven testcases was updated to contain
measured values from traffic generator in CSV report
* method for ovs flow comparison was modified to normalize
IPv4 CIDR network addr (e.g. 10.0.0.5/8 => 10.0.0.0/8)

Open vSwitch with DPDK can optimize memory usage
in case of NUMA architecture to avoid unnecessary
memory access across NUMA slots. In a nutshell,
PMD threads serving virtual NICs are co-located at
the same NUMA slot as QEMU instance, which is using
these NICs.
This patch adds new (functional) integration testcase,
which verifies OVS vHost User numa awareness feature.
Step driven test objects were updated to allow a call
of OS utilies and evaluation of conditions. Also the
documentation was updated with the list of supported
test objects and their methods.
