>Description:
ix0-device is not working then configured within lagg(4).
It works however then configured standalone.


>How-To-Repeat:
Setup:
rc.conf:
cloned_interfaces="lagg0"
ifconfig_ix0="up"
ifconfig_em0="up"
ifconfig_lagg0="laggproto failover laggport ix0 laggport em0 192.168.0.222 netmask 255.255.255.0"

Both cards are connected to a 1G switch. Operating fine then configured standalone.
However, with the setup above lagg0 is NOT responding to the inbound ping requests nor outbound if em0 has no carrier.
Then cable is plugged to em0 but pulled from ix0 lagg0 responds to inbound ping.

Jack Vogel as a maintainer is contacted to investigate this.
