Mysterious crashes in DPDK application when using the pcap driver.

I was experiencing mysterious crashes in my DPDK application when using pcap virtual devices (using the --vdev option). What's more, when there was more crashes, I didn't seem to be getting all the packets I should have. So I investigated, and found out I was attempting to capture packets from multiple threads. That seems to be a no no with the pcap driver, considering it explicitly does not support multiple queues. I limited the number of cores available to my application using the -c option, and everything was solved.
