The network stack in eCos is from FreeBSD. I suggest you look at the
sources for the route command from FreeBSD and test your code on a
FreeBSD machine. It probably does things a little different than
Linux.

You can see the source for the FreeBSD route command at
http://www.freebsd.org/cgi/cvsweb.cgi/src/sbin/route/route.c
