Introduce reconfig suites, for dot1q+ip4+vxlan
Ticket: CSIT-1551 + Config copied from other suites. + Layer keywords prepared for additional chains. + Renamed "create" argument to "vlan_per_chain". + TrafficGenerator result extraction improvements. + Also unified TG type and subtype checking. + Throughput estimated as PDR for zero PLR. + Actual Qemu start is skipped. + Parse xstats instead of stats in trex stop scipt. - Because stats are unconditionally cleared on each script connect. + Remember start values to get better ReceiveMeasurementResult at stop. + Expose loss count and time as appropriate test message. + Autogen support. + Multiple chain amounts and core densities. - Only 1 additional chain. + Proper TAGs. Documented. + Clarified min framesize tags are for TG-DUT. + Added a TODO concerning overhead values. + Added 118B tag. + Robot performance keywords improvements. + Added missing return value documentation. + Frame size as required test variable, not an explicit argument. + MLRsearch keyword to store result (not into test message). - TODO: De-duplicate: main keyword to measure, minor to set test message. - But implementation uses the fact default arguments are different. + Keywords for starting and stopping background traffic. - No checks whether start-stop pair is complete. + Multiple minor indentation and logging improvements. - Missing / TODOs: - Support also vlan_per_chain=True? - Support dot1q without vxlan? - Support also deletion? - How to package config steps so -reconf can be generated from -ndrpdr?
