Receive Status Threshold register. The receive status threshold are used to
set a limit on the amount of receive status which is held in the receive status
FIFO before a bus request will be scheduled. When the number of words in
the FIFO exceeds the threshold value, the Descriptor Processor will schedule
a bus request to transfer status. The actual posting of the bus request may be
delayed due to lack of resources in the MAC, such as the RXStsEnq register
being equal to zero. The lower two bits of the thresholds are always zero.

Transmit Data Soft Threshold. The hard and soft threshold
work in exactly the same manner except one. The soft
threshold will not cause a bus request to be made if the
bus is currently in use, but only when it is deemed to be
idle (no transfers for four AHB clocks). The hard threshold
takes effect immediately regardless of the state of the bus.
This operation allows for more efficient use of the AHB bus
by allowing smaller transfers to take place when the bus is
lightly loaded and requesting larger transfers only when
the bus is more heavily loaded.
