Hi,

Please consider this patch to the implementation of the 'inet6 auto'
stanza for kfreebsd.  In the current one (which I wrote) I erroneously
tried to enable accept_rtadv via the sysctl, which is global, and
doesn't affect the interfaces that are already attached.

The correct way to do this (and have tested) is as follows:

--- a/ifupdown-0.7.47.2/inet6.defn      2013-10-19 19:24:55.000000000 +0100

Thanks!
