 Yes I'll guess kernel config would be the first step. Also we need to
 find out if there are any useful options to current FIB. Which is very
 general purpose.

 Anyway we have a cleaner interface to FIB also we have some new FIB options.
 Which should be a step forward and an advantage for linux and will hopefully 
 lead to more development and understanding and so that Linux will used for 
 development in this area. We will also lead to better understand the dst 
 hash and FIB trade off.

 Experiences from tests or use are very welcome.
