The idea seems reasonable enough, but I think the implementation requiring
the user to pass in special "magic numbers" for the offload values is not a
good idea. Perhaps add in a separate flag for "no-csum" to disable that.

For the no-rss case, can you explain how you would see this app being used
in the absense of RSS support to distribute traffic among the separate
processes?
