Abstract
A method and device of creating one or more buffer structures in a shared memory that exists between a host and a network device is disclosed. The method includes the step of storing within a block of shared memory an administration block having a base address and a descriptor ring parameter, which includes information relating to a descriptor ring and frame data buffer sizes. The base address of the administration block is written into the network device. An initialization command is then issued from the host to the network device. The network device reads the administration block and shared memory and one or more descriptors are constructed within the network device. Each descriptor points to a frame data buffer within shared memory. The descriptors are then stored.
