ABSTRACT:
A method for providing efficient use of a transmit engine in transmitting packet directing information. In one embodiment, two linked lists are used to submit packets and packet directing information to a transmit engine. When there is no packet to send, both lists are marked as free. When software desires to send a packet to hardware, the packet is placed on the first linked list. Software marks the first linked list as busy. If the transmit engine is not busy with the second linked list, software will start the transmit engine utilizing the first linked list. While the first linked list is marked as busy, all additional packets are directed to the second linked list. When the packets of the first linked list have been sent, software marks the first linked list as free.
