Hi, I am looking for a way to create buffers inside rumprun kernel and mmap to user space in order to avoid the kernel-userspace packet copy.. This is well known implementation in the linux, but I don't see anything in the rumprun kernel. I quickly checked the pcap library whether BPF enables HAVE_ZEROCOPY_BPF, but unfortunately it was not.. also setsockopt does not seem to provide a ring creation. Is there a way to achieve the same effects?
Thanks, Jinho
