Abstract
Disclosed herein is a system including a network interface arranged to receive a data frame from one or more communication networks. A frame filter is arranged to receive the data frame from the network interface, wherein the frame filter selectively outputs the data frame to at least one of a second network interface or a direct memory access (DMA) controller based on a data frame type. The DMA controller is arranged to store a received data frame to shared memory and transmit an interrupt signal to a media access control (MAC) driver after the received data frame is stored in the shared memory so that the MAC driver can initiate an interrupt handler in response to the interrupt signal to retrieve the stored data frame.
