This is a early (alpha) view of my recent work to to update (gut job) of the RSS handling in the tap device. The rework was so big that it did not make sense to do it in incremental stages.
Overall it comes out much simpler and cleaner. Much more testing is needed, at this point it will load the program and try and setup filter (but fails).
