Hi there, A DPDK can run on top of XDP sockets and use custom XDP program to split the traffic between the Linux stack and the DPDK application. This way still allows zero copy between the kernel and the DPDK application. Is there another zero-copy way to achieve redirecting some part of the traffic to the Linux kernel and another to a DPDK application? For example, AFAIK I can run the DPDK application and redirect packets from inside to the Linux stack via the DPDK KNI functionality but it'll be much slower because it'll require packets copying and context switch (if I'm not mistaken).
Regards, Pavel.
