TST: Transmit Start Threshold. The transmit start threshold
defines the number of bytes that must be written to the
transmit data FIFO before a frame will start transmission
on the serial interface. This value is primarily of concern
when the transmit frame is spread across multiple
descriptors and the first descriptors define small amounts
of data.
