A first component of a computing environment receives, from a physical network adapter of the computing environment, a request that the first component take over processing of network frames directed to network frame address(es) associated with a second component of the computing environment. The first component register the network frame address(es) for processing of network frames directed to the network frame address(es). Based on the first component receiving from the physical network adapter a network frame directed to a network frame address of the network frame address(es) associated with the second component, the first component processes the received network frame, in which the network frame is provided to the second component via an inter-component link between the first component and the second component.
