From: "Alexander V. Chernikov" <melif...@freebsd.org>

Current logic always selects an IFA of the same family from the
 outgoing interfaces. In IPv4 over IPv6 setup there can be just
 single non-127.0.0.1 ifa, attached to the loopback interface.

Create a separate rt_getifa_family() to handle entire ifa selection
 for the IPv4 over IPv6.
