Observation. Two instances of testpmd. Only one report shows correct stats when you run 16 queues on RX with the default RSS config. i.e rss-ip , rss-udp etc. You only see the counter for a single queue.
How I know I took last report on first intestine test-pmd at the end of run, take all bytes added. I know time I run compute pps correlated to the PPS in the actual switch. so either ICEN or IAVF doesn't report stats (only for queue 0) On Fri, Apr 18, 2025 at 10:30 PM spyroot <spyr...@gmail.com> wrote: > Hi Folks, > > > I am observing that DPDK test-pmd with IAVF PMD, ICEN PF driver, > > reporting statistics incorrectly when the RX side generates a UDP flow that > randomizes or increments IP/UDP header data (IP/port, etc). > > I tested all 23.x stable and all branches. > > > -If I use *single* flow (on the TX side, all tuples are the same on the RX > > HASH() produce -> same result). no issue. > > So, on the RX side, I see all zero packet drops and the correct pps value > reported by test-pmd. > > > - If I increase the number of flows ( IP/UDP, etc.), the PPS Counter and > byte/pkt counter > > report only single queues.
