Hi,

that is indeed very similar to what we are thinking ourselves. Is there any of
what you have already done that you could contribute publically to save us
duplicating some of your effort? [The one big difference, is that we are not
thinking of enabling kni permanently for each port, as the ethtool support is
only present for a couple of NIC types, and solving that is a separate issue.:-)]

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.
