Transmit Descriptor Queue Base Length register. The Transmit Descriptor
Queue Base Length defines the actual number of bytes in the transmit
descriptor queue, which thereby sets the maximum number of transmit
descriptors that can be supplied to the MAC at any one time. The length
should be set at initialization time and must define an integral number of
transmit descriptors.
