Transmit Descriptor Enqueue register. The Transmit Descriptor Enqueue
register is used to define the number of valid descriptors available in the
transmit descriptor queue. Only the Transmit descriptor Increment field is
writable and any value written to this field will be added to the existing
Transmit Descriptor Value. When complete descriptors are read by the MAC,
the Transmit Descriptor Value is decremented by the number read. For
example if the Transmit Descriptor Value is 0x07, and the Host writes 0x03 to
the Transmit Descriptor Increment, the new Value will be 0x0A. If the controller
then reads two descriptors, the Value will be 0x08.
