Refactoring the PF_ROUTE ABI is probably a task for the 6-CURRENT lifetime. If done right, we could MT5 it as we go along.

This probably needs to happen using a different protocol family to begin with, with the old PF_ROUTE kept on board as a shim; notice that PF_KEY_V2 is explicitly numbered as such, and has much in common with how routing sockets and messages are dealt with. A Tag/Length/Value scheme might be more appropriate; things like dealing with netmasks are very hairy indeed. This is not so much on my TODO list as my WISHLIST right now, XORP could certainly benefit.
