Hi folks, Here is what I want to do : "Intercept all incoming IP packets on an Ethernet interface of a certain type (e.g RSVP) and call my own function to process, all inside the kernel" Netgraph nodes : ng_iface, nf_bpf (and probably ng_ether) look promising for this task but I can not figure out how to do it in practice... Any help is appreciated. Thanks, neo
