    Abstract: Generally, this disclosure relates to adaptive interrupt moderation. A method may include determining, by a host device, a number of connections between the host device and one or more link partners based, at least in part, on a connection identifier associated with each connection; determining, by the host device, a new interrupt rate based at least in part on a number of connections; updating, by the host device, an interrupt moderation timer with a value related to the new interrupt rate; and configuring the interrupt moderation timer to allow interrupts to occur at the new interrupt rate.

    Abstract: Examples described herein relate to a device indicating a number of available interrupt messages that is more than physical resources available to store the available interrupt messages and allocating one or more physical resources to provide one or more interrupt messages based on allocation of the one or more interrupt messages to a destination entity. The destination entity can request a maximum permitted allocation of interrupt messages regardless of interrupt message use level. The destination entity can request a maximum permitted allocation of interrupt messages regardless of interrupt message use level and allocate the requested maximum permitted allocation of interrupt messages for use in a configuration region of a device. However, based on unavailability of a physical resource to store a first interrupt message, allocation of the first interrupt message to a destination entity may not be permitted.

    Abstract: Methods, apparatus, and systems for implementing a semi-flexible Receive Segment Coalescing (RSC) control path. Logic for evaluating packet coalescing open flow criteria and close flow criteria are implemented in hardware on a network device that receives packets from one or more networks. packet coalescing open profiles and packet coalescing close profiles are also stored on the network device, wherein each packet coalescing open profile defines a set of packet coalescing open flow criteria to be applied for that packet coalescing open profile and each packet coalescing close profile defines a set of packet coalescing close flow criteria to be applied for that packet coalescing open profile. packet coalescing open flow and close flow profiles are then assigned to packet coalescing-enabled receive queues on the network device and corresponding open and flow criteria are used to perform packet coalescing-related processing of packets in the receive queues. The scheme supports hardware-based packet coalescing packet processing while providing flexibility in meeting the requirements of different operating systems and future usage models on a single network device.
