Descriptions

Bit	Field	Value Description
31-0	RX_HDP	Rx Queue Head Descriptor Pointer: This field is the host memory address for the first buffer
		descriptor in the channel receive queue. This field is written by the host to initiate queue receive
		operations and is zeroed by the port when all free buffers have been used. An error condition
		results if the host writes this field when the current field value is nonzero. The address must be
		32-bit word aligned.
