[Radiusplugin-devel] [PATCH] bird support

[Samuel Thibault]

This migrates to the use of the "ip" command instead of "route", in order to
be able to append "proto static", since this is really a static route entry
that routing daemons should follow; it's neither an ICMP redirection, nor an
autoconfed kernel route, nor a bootup route, nor an RA route.
