Personally I was looking at something a bit different because I wanted an 
ability to support lightning fast BPF expressions for security purposes, not 
just debugging captures.

I got hold of a copy of the bpfjit implementation, with some tweaks to support 
compiling on Linux and BSD in userspace mode, from Alexander Nasonov who made 
it for the BSD kernel, as a result of participating here.

I am planning to use this to do the captures so you don't incur the headache 
or performance issues with rte_kni.

I am curious how I might be able to link it up w/ the standard libpcap based 
tools to get an end-to-end solution with minimal loss.
