Just curious: does it work if you split the lagg configuration from the IP
config:

ifconfig_lagg0="laggproto ..."
ifconfig_lagg0_alias0="inet 192..."

I've had problems in the past with cloned interfaces not working right if
you do everything in one ifconfig line. Never spent much time debugging it,
though, as the split config always worked.
