Can I ask about the purpose of these changes?
Right now in  l3fwd both lpm and hash tables are static and hard-coded.
we initialize them at startup and then just do read from them.
Do you plan to enhance l3fwd with ability to dynamically update tables contents?
Though fir that we first have to get rid of hard-coded values (config file or so).
