Abstract
Roughly described, method for managing data transmission between a host subsystem and a network interface device, in which the host writes data buffer descriptors into a DMA descriptor queue, and the network interface device writes completion events to notify the host when it has completed processing of data buffers. Each of the completion event descriptors notify the host of completion of data transfer between the NIC and one or more of the data buffers, and can also embed a queue empty notification inside the completion event.
