These bits control the threshold level of the MTL
Transmit FIFO. Transmission starts when the frame
size within the MTL Transmit FIFO is larger than the
threshold. In addition, full frames with a length less
than the threshold are also transmitted. These bits are
used only when Bit 21 (TSF) is reset.
