Is there a way to process > ethernet header with ng_bpf ? once you have worked out what the framework is doing then it is very easy to read the code of netgraph modules because each module does only one thing. read the sample module for descriptions of what the parts do and then look at the modules you are trying to use. it should be pretty quickly obvious what they are doing.
