--- Comment #2 from dgilbert@eicat.ca ---
I've done some additional work on the problem.  One thing I have done is to
enable the rc.conf variable

ipv6_activate_all_interfaces="YES"

... which changes the ifconfig for the ngX interfaces to say:

ng11: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu
1436
        inet 66.96.31.6 --> 66.96.16.50 netmask 0xffffffff
        inet6 fe80::219:b9ff:fef9:b9e7%ng11 prefixlen 64 scopeid 0x17
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

(this removes IFDISABLED ... which shouldn't matter for ipv4, but I'm working
on ipv6 anyways).

The 2nd thing I've done is compare the 9.1 and 10.0 versions if ng_iface.c. 
The main difference appears to be a rewrite of ng_iface_output() to make it's
third argument a constant.  I'm unsure reading this if the handling of the
dst->sa_family could be causing my problem.
