Abstract
Packet information is stored in split fashion such that a first part is stored in a first device and a second part is stored in a second device. A split packet transmission DMA engine receives an egress packet descriptor. The descriptor does not indicate where the second part is stored but contains information about the first part. Using this information, the DMA engine causes a part of the first part to be transferred from the first device to the DMA engine. Address information in the first part indicates where the second part is stored. The DMA engine uses the address information to cause the second part to be transferred from the second device to the DMA engine. When both the part of the first part and the second part are stored in the DMA engine, then the entire packet is transferred in ordered fashion to an egress device.
