Then your best option is to patch lagg(4) with an avail algorithm, that 
prefers $master and sticks with an interface till it's detected down. When 
done properly the chances are good to get this into base.
Another approach would be to change the failover with a 'fader' algorithm, 
that gradually fades from one nic to the other, kind of like an audio mixer, 
though I'm not sure if that's possible and would work satisfactory.

 The problem we're having is when nfe0 comes online again, a failback occurs
  making nfe0 active again. This causes a momentary network outage that we
  want to prevent. Is there a way to configure the lagg device to stay with
  the currently active interface, even if the MASTER interface comes back
  online?
