Let the NIC router provide an Uplink service besides the Nic service that it already provided. Requests for an Uplink session towards the NIC router are assigned to Domains using the same <policy> configuration tags that are used in order to assign Nic session requests. The MAC addresses of Uplink session components are _NOT_ considered during the allocation of MAC addresses for NIC session components at the same Domain. The task of avoiding MAC address clashes between Uplink session components and Nic session components is therefore left to the integrator. Apart from that, Uplink session components are treated by the NIC router like any other interface. Ref #3961
