Mahesh you're running into one of the 2 or 3 internal bonding mode
changes that haven't been upstreamed.
Some sort of lacp churn machine and faster/better link up/down/change
notification propagation are among them.
We really should clean those up and get them submitted.

You should probably do this development on upstream 3.15 ;-)
