Abstract
A cable modem interface unit transmits packets to a packet source. The packet source sends control packets to a cable modem and requires a reply control packet in response to sending a control packet. The cable modem interface unit is coupled to the cable modem and a network driver interface layer. The interface unit generates a reply control packet in response to receiving a control packet from the cable modem. The reply control packet is queued in a transmit stack in the interface unit. The transmit stack includes data packets received from the network driver interface layer. The interface unit sends the reply control packet and the data packets from the stack to the cable modem so that they are eventually sent to the packet source.
