1. What you and Vladimir have done to this code kicks total ass and will be a 
huge help so I am very excited to squeeze in some cycles somewhere to test all 
of this stuff out ASAP.

2. Vladimir's changes were somewhat smaller, but Stephen yours are larger. 
Stephen, if you could place them into a cloned copy of DPDK or a branch 
somewhere for convenient pickup, I think I could help you make a lot of progress.

I could help test these fixes in a second app besides your own to get some 
cross validation, and help make the required cleanups, so we could get a bit 
more external validation before we try to negotiate a safe way to merge them 
upstream to Bruce since he is marked as the LPM maintainer.

My DPDK fork is located here, for example, but it could really be anywhere you 
like to put it which I could access. Or even a one-off zip or tarball with the 
git repo inside and I could host it in my fork or give you access on the fork 
to push it as a second remote if you are OK to do that...
