Diagnostic Address Register. The Diagnostic Address Register provides an
indirect addressing method to point to internal diagnostic locations, which
provide access to features not required for normal driver operation. To access
the internal registers, the address of the register is written to the Diagnostic
Address register, and the Diagnostic Data register is used to access the actual
data.

Soft Reset. This is an act-once bit. When set, a Soft Reset
is initiated immediately, this will reset the FIFO, mac and
Descriptor Processor. This bit is cleared as a result of the
reset. Driver software should wait until the bit is cleared
before proceeding with MAC initialization.
Reserved. Unknown During Read.
