Receive Header Length register. The Receive Header Length registers are
used to generate status after receiving a specific portion of a receive frame.
When the number of bytes specified in either register has been transferred to
the external data buffer, an appropriate status is generated. The status for a
receive header will reflect the number of bytes transferred for the current
frame, the address match field will be valid, and the other status bits will be set
to zero. A status will only be generated for header length 2 if the length is
greater than that specified for header length 1.

Transmit Descriptor Base Address register. The Transmit Descriptor Queue
Base Address defines the system memory address of the transmit descriptor
queue. This address is used by the MAC to reload the Transmit Current
Descriptor Address whenever the end of the descriptor queue is reached. The
base address should be set at initialization time and must be set to a word
aligned memory address.
