Public Attributes
ahci_fis_type_t	fis_type: 8
	fis type
uint8_t	port_multiplier: 4
	Port multiplier.
uint8_t	reserved0: 1
	Reserved.
uint8_t	direction: 1
	0: host2device 1: device2host
uint8_t	interrupt: 1
	Interrupt Bit.
uint8_t	auto_active: 1
	Auto-activate. Specifies if DMA Activate FIS is needed.
uint8_t	reserved1 [2]
	Reserved.
uint64_t	dma_buffer_id
	DMA Buffer Identifier. Used to Identify DMA buffer in host memory. SATA Spec says host specific and not in Spec. Trying AHCI spec might work.
