It would likely be similar to how we currently "set"/attach an XDP program, via its BPF file-descriptor to an ifindex. Eric Leblond, choose to hide this in the kernel library "libbpf", see code: function bpf_set_link_xdp_fd() https://github.com/torvalds/linux/blob/master/tools/lib/bpf/bpf.c#L456-L575 Given Suricata already depend on libbpf for eBFP and XDP support, then it might make sense to add an API call to "get" XDP link info, e.g. bpf_get_link_xdp_features(int ifindex) ? -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer _______________________________________________ iovisor-dev mailing list iovisor-dev@lists.iovisor.org https://lists.iovisor.org/mailman/listinfo/iovisor-dev
