I connected two 1g in back to back mode and executed: sudo ./build/app/testpmd -c 0xF -n 4 -- -i --portmask=0x2 --nb-cores=2 start (and start tx_first) stop I see 0 counters for rx/tx. I removed the two 1g from uio driver and added two 10g 82599EB and reran the test - still 0 traffic. Wondering where to debug. thx
