Receive Descriptor Queue Base Length register. The Receive Descriptor
Queue Base Length defines the actual number of bytes in the receive
descriptor queue, which thereby sets the number of receive descriptors that
can be supplied to the MAC. The length should be set at initialization time and
must define an integral number of receive descriptors.
