Adding netlink support to pfinet won't contribute much, iproute2 (the
only major package afaik that uses netlink) is a bit too dependent on
the linux kernel's header files, even where you to fix the dependencies
and other minor issues, adding routes wont allow dhcp to work. As I
previously told you[0], dhcp needs to forward packets with an address
of INADDR_NONE wich can't happen unless the socket tells pfinet wich
interface to use, ISC dhcp does that on linux-2.0[1] (even in the
single interface case) using the SO_BINDTODEVICE sockopt, you need
pfinet to process that option otherwise packets from sockets without a
bound device will be dropped in ip_route_output_slow().
