I am new to DPDK, but I have been tasked with researching it's capabilities. One of the things I am trying to understand is how it would interact with some kind of packet capturing application. One of the things I use to grab a packet from the Linux Kernel is using netfilter hooks to get the packet and capture it. Does DPDK have something like netfilter hooks?
I am trying to understand how you would do a packet capture on a DPDK controlled port. Is possible to packet capture all traffic on the port from a single application/module or can you only do packet capture within the DPDK application itself meaning you can't see traffic being processed by other DPDK applications? Thanks.
