Enumeration Type Documentation

enum unsolicited_frame_state

enum unsolicited_frame_state -

This enumeration represents the current unsolicited frame state. The controller object can not updtate the hardware unsolicited frame put pointer unless it has already processed the priror unsolicited frames.

Enumerator:

UNSOLICITED_FRAME_EMPTY	This state is when the frame is empty and not in use. It is different from the released state in that the hardware could DMA data to this frame buffer.
UNSOLICITED_FRAME_IN_USE	This state is set when the frame buffer is in use by by some object in the system.
UNSOLICITED_FRAME_RELEASED	This state is set when the frame is returned to the free pool but one or more frames prior to this one are still in use. Once all of the frame before this one are freed it will go to the empty state.
UNSOLICITED_FRAME_MAX_STATES
