This problem can be repeated without mpd:
# ifconfig vlan408
vlan408: flags=8844<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=3<RXCSUM,TXCSUM>
ether 00:04:23:ba:2a:7a
inet 10.25.1.244 netmask 0xffffff00 broadcast 10.25.1.255
...
# kldload ng_iface
# ngctl mkpeer . iface foobar inet
# ifconfig ng0 192.168.100.100/32 10.25.1.245
# ifconfig ng0
ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1500
inet 192.168.100.100 --> 10.25.1.245 netmask 0xffffffff
# arp -s 10.25.1.245 00:04:23:ba:2a:7a pub
cannot intuit interface index and type for 10.25.1.245
This commands work fine on RELENG_7, but don't work on RELENG_8 or
CURRENT, and it seems to be regression.
