> 
> On Fortville NIC, link status change interrupt callback is not executed when
> slave in bonding is (re-)started. It causes that slave's NIC is inactive even
> if its link status is up on the start.
> 
> This patch invokes lsc callback, just after port's start, to check its initial
> link status and manage properly.
