IPv6 not disabled in mpd.conf w/ IPv6 GUI option set to 'disabled'
-
It seems like my ISP (Fairpoint) added IPv6 support last night at 1AM. This broke my connectivity, even though IPv6 was proactively disabled in my PPPoE config.
I commented out:
set bundle enable ipv6cp
in my mpd_wan.conf file and ran mpd5 by hand, and the link came back up just fine. Attaching logs snippets for now; when I get a few spare cycles I can look at a patch if somebody else doesn't first.
This problem appears to have been initially reported here.

Well, this solves my problem. Not sure it's exactly right for IPv6 use cases.
