ixia: Bugfixing and burst type enhancement
A support for proper reporting of "Burst" traffic type was added. Several bugs were fixed: * RFC2544 Throughput - end of search condition was moved to avoid situation, that another iteration is executed but its results dropped * RFC2544 Throughput - pause after each iteration was added to ensure that all frames are cleared from buffers; It improves stability of results. Also "received" values are no longer higher then "sent" values. * VSPERF will report also the number of sent and received frames * VSPERF will correctly process send and received values - they were switched on several places JIRA: VSPERF-149 JIRA: VSPERF-562 Change-Id: I8a5caa6385a1ef86aa4bf4511d2753100ed0ab14 Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Sridhar Rao <sridhar.rao@spirent.com> Reviewed-by: Richard Elias <richardx.elias@intel.com> (cherry picked from commit be271aef854887fce72d821a8589dfd4ebbe8e1d)
