RX_CP

Rx Queue Completion Pointer: This field is the host memory address for the receive queue
completion pointer. This register is written by the host with the buffer descriptor address for the last
buffer processed by the host during interrupt processing. The port uses the value written to
determine if the interrupt should be deasserted.
