Abstract
A method and structure for determining when a frame of information comprised of one or more buffers of data being transmitted in a network processor has completed transmission is provided. The network processor includes several control blocks, one for each data buffer, each containing control information linking one buffer to another. Each control block has a last bit feature which is a single bit settable to 'one' or 'zero' and indicates when the data buffer having the last bit is transmitted. The last bit is in a first position when an additional data buffer is to be chained to a previous data buffer indicating an additional data buffer is to be transmitted and a second position when no additional data buffer is to be chained to a previous data buffer. The position of the last bit is communicated to the network processor indicating the ending of a particular frame.
