I needed some clarification w.r.t pktgen > Whether throughput, loss and latency can be measured by point to point > connection between test system and DUT(Without switch)? Throughput and packet loss is done within the code, but a percentage of los= s is not calculated. Latency is a bit tricky as the sent from pktgen needs to return to the same= port and CPU to get a latency number. The latency must be enabled on the p= ort to get the value. The reason it needs to be the same port/core is the c= ounter used is the per core timestamp register. > If yes, then > where should pktgen tx and rx should run? Not sure about this question, normally pktgen run on one machine targeting = the DUT, but you can run pktgen on the machine or the DUT, just a bit more = complex of a setup. > Is support for RFC-2544 test specification complete? I have a script in the repo that tries to do rfc2544 like test, but may not= the best script. > Is their any development activity going on for RFC-2889?
