Hi Is XDP designed for implementing packet forwarding? Is there an example of ipv4 forwarding the kernel? I don't find any example in samples/bpf/ directory. I'm also looking at XDP implementation in i40e driver. Is there a reason we need to use eBPF program for packet forwarding? Is it possible to use percpu kernel thread instead of an eBPF program? DPDK creates user thread for each CPU core. Each user thread processes packet independently in a lockless manner. I'm wondering if XDP can do something like that inside kernel (possibly using workqueue). Looking forward to your suggestions. Many thanks Tamim PhD Candidate, Kent State University
