[Unbound-users] outgoing-interface config option

[Николай Брыскин]

Hello, I'm using libunbound in my application (proxy server), and I
need to configure libunbound with specific outgoing interface for DNS
requests.
I've wrote this patch (tested with libunbound 1.4.9 and 1.4.12):

               /* unknown or unsupported (from the set_option interface):
                * interface, outgoing-interface, access-control,

I have not found functions like S_STR for this functionality, so it
looks quite ugly.
Could you add this or similar patch to the upstream?
