Unchanged
Receive Status Enqueue register. The Receive Status Enqueue register is
used to define the number of free entries available in the status queue. Only
the Receive Status Increment field is writable and any value written to this field
will be added to the existing Receive Status Value. Whenever complete
statuses are written by the MAC, the Receive Status Value is decremented by
the number read. For example, if the Receive Status Value is 0x07, and the
Host writes 0x03 to the Receive Status Increment, the new Receive Status
Value will be 0x0A. If the controller then reads two descriptors, the Value will
be 0x08.
