Abstract:
1. A method comprising: receiving, from a network interface of a computing device, information on one or more capabilities of a network presence offload component of the network interface, including information on first and second network presence offload functions supported by the network presence offload component; configuring the network presence offload component, based on the information on the one or more capabilities of the network presence offload component, to perform the first network presence offload function during a low power state, the configuring performed through a single offload interface that is an interface between an operating system of the computing device and a device driver for the network interface; allocating, based on the information on the one or more capabilities of the network presence offload component, the second network presence offload function to be performed by a processor of the computing device during the low power state; responsive to the computing device transitioning to the low power state, enabling the network presence offload component of the network interface; in response to receiving a message over the network connection, providing, via the network presence offload component, a reply over the network connection without waking up other components of the computing device, the reply being based at least in part on the message being associated with the network presence offload function; and storing information associated with the reply in the network presence offload component.
