first frame uses Data buffer 0 only and there are two status entries associated with it. The first
status (status 0) is for the reception of a receive header and the second (status 1) is for the
end of frame/buffer, both status entries point to the beginning of data buffer 0. The second
frame occupies two buffers (data buffers 1 and 2), and three status entries (2, 3, and 4).
Status 2 is for the receive header, status 3 for the end of buffer 1 (frame size larger than
buffer size), and status 4 for end of frame/buffer. The next two frames both occupy one data
buffer each and one status each. This could be the case for short frames that do not exceed
the header size or the buffer size. The result of this is that the status queue may be used at a
different rate to the descriptor queue, based on the type of traffic and the options selected.
