Hi,
I've made a trivial patch that resolves IPv6 scope names (according to
rfc4291).
I thought this might be handy, so one does not have to memorize what id
refers
to which scope. And it's a nice opportunity to get my feet wet I guess :)
This is my first patch and I have no idea what's the best way to contribute
to the
project (probably I didn't look hard enough or in the wrong places).
Feedback and pointers appreciated.
Kind regards,
raichoo
