Network and adaptor with time-based and packet number based interrupt combinations

摘要

A network adaptor that generates interrupts to a host system when data is received from the network or downloaded from system memory for transmittal over the network. The adaptor generates interrupts after a delay determined by an interrupt deferral mechanism, which includes one or more timers and/or one or more counters. Interrupts are generated, for example, after a predetermined time has elapsed after a DMA completion or after a certain number of packets are counted.
