Hmm, you could do it that way.  How about a simple system where by each
module simply adds itself to a list of protocols it can speak, and what the
function call is? They all take the same parameters, so it's not a biggie.

That way, i get an ipv4 packet, i simply do

net_input(IPV4, ...)

The net module knows where to find the ipv4_input function and so calls
it...

Dunno really.
