Jiri, you agreed to a name change? ;-> I want to have some of what
David A. ate yesterday.

I agree it is a good idea to have arbitrary size bitmask so we dont
run out of bit space but we need to restrict the max length possible.
I dont agree to using the netlink.h as the best location for this
but lets move on.
Do you or David A. want to take a crack at this?  I am a little tied
up.

cheers,
