I applied these patches, and they have fixed the issue with the descriptors. There are now 32768 per queue. I have tested with testpmd, and the ports work. However, I am unable to initialize the ports with pktgen. Initialize Port 2 ...

Do you have any suggestions as to what to do next? Regards, Oluwaseun
