Abstract
Provided are a method, system, network processor, network device, and article of manufacture for enqueueing entries in a packet queue referencing packets. When adding a packet to a first memory area, an entry is written to a packet queue in a second memory area referencing the added packet. A pointer is read referencing one end of the packet queue from a queue descriptor in the second memory area into a third memory area in one read operation. The pointer is updated in the third memory area to point to the added entry in the packet queue and the updated pointer in the third memory area is written to the queue descriptor in the second memory area in one write operation.
