Abstract
A method of generating frame receive interrupts in an Ethernet controller including receiving incoming data frames and storing data frames into a receive queue, monitoring the number of received data frames, and when the number of received data frames exceeds a first threshold, generating a frame receive interrupt. In another embodiment, the method further includes monitoring the amount of received data stored in the receive queue and generating a frame receive interrupt when the first threshold is exceeded and when the amount of received data stored in the receive queue exceeds a second threshold. In yet another embodiment, the method further includes monitoring the time duration of the data frames stored in the receive queue, and generating a frame receive interrupt when the number of received data frames exceeds the first threshold or when the time duration of the data frames stored in the receive queue exceeds a third threshold.
