    igb: Reinitialize through iflib after media changes
    
    A media change can require a complete controller reset.  Resetting the
    controller directly from the admin task leaves iflib rings, filters, and
    interface state programmed for the pre-reset controller.
    
    Request an iflib reset for every media change.  This already was done
    when SR-IOV was active; use the same lifecycle for the ordinary PF case.
