Receive Status Queue Current Length. The Receive Status Queue Current
Length defines the number of bytes between the Receive Status Current
Address and the end of the receive status queue. This value is used internally
to wrap the pointer back to the start of the queue. The register should not
normally be written to.

Receive Status Queue Current Address. The Receive Status Queue Base
Address defines the system memory address of the receive status queue.
This address is used by the MAC to reload the Receive Status Queue Current
Status Address whenever the end of the status queue is reached. The base
address should be set at initialization time and must be set to a word aligned
memory address.
