Allow IPsec interface to have SAs reset
Make it easier to integrate with external IKE daemon. IPsec interfaces can have one or both SAs replaced after creation. This allows for the possibility of setting a new child SA on an interface when rekeying occurs. It also allows for the possibility of creating an interface ahead of time and updating the SA when parameters that are negotiated during IKE exchange become known.
