to the transmit queue for segmentation. The process is as follows:

The host links the buffer descriptors (in SAR-shared memory) for the
associated data buffers (in host memory) containing the PDU to be
segmented.
The host then formats a 2-word transmit queue entry and writes this entry
to the transmit queue. The location of the first buffer descriptor in the
linked chain is contained in the transmit queue entry.
The segmentation coprocessor automatically senses the presence of new
transmit queue entries, reads them, and schedules the new data for
transmission. The transmit queue acts as a FIFO buffer for segmentation
task pointers.
