/**
 * The HP 3800 OF driver does the following:
 *
 * 1. listen for node added/removed in inventory (future: filtered by device type)
 * 2. when a HP 3800 node is added, register the routed RPCs (other driver types may register as DCLs for a feature such as vlan)
 * 3. when a HP 3800 node is removed, close the RPC registration (and/or DCLs for other driver types)
