I got quite a few these messages "*PMD: Trying to receive pkts while device is NOT running*" when the application starts. May i ask what does this message mean? 2. I tried to capture packets for all queues (8 rx queues in total) for the ENA device, however i always got "*ena_queue_start(): Failed to populate rx ring*" error. If i captured rx queue 0 only, the DPDK application didn't report this error. May i ask if anyone know any caveats to capture all queues for ENA device ? Thank you so much ! -- Regards, Zi-Liang Mail:zlchen.ken@gmail.com
