Delete a Subnet. Removes the Subnet with the given network index from the node. The node will stop sending Network Beacons with the given Subnet, and can no longer process messages on this Subnet. All Applications bound to this Subnet are also deleted.
Resolve the message encryption keys, given a message context. Will use the @c ctx::app_idx and @c ctx::net_idx fields to find a pair of message encryption keys. If @c ctx::app_idx represents a device key, the @c ctx::net_idx will be used to determine the net key. Otherwise, the @c ctx::net_idx parameter will be ignored.
