trex: Add support for burst traffic type
Support for burst traffic type was added into T-Rex. This traffic type is useful for tests, where a limited number of frames should be sent through DUT. JIRA: VSPERF-562 Change-Id: I03b7150e66a0210cce91b20c751b8624c16f951b 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 e9ff0fdf355d26d0c171c6c1137c4beb12561233)
