Table 3–2		PHY Link Error Status Block Information
	SATA AAMUX PHY ERRORS
	H-RX		The number of SATA FIS CRC errors received on the host port of the AAMUX
	H-TX		The number of SATA R_ERR primitives received on the host port indicating a problem
			with the transmitter of the AAMUX
	H-Link		The number of times the PHY has lost link on the host port.
	H-Disp		The number of frame errors for the host port of the AAMUX. These include: code error,
			disparity error, or realignment
	O-RX		The number of SATA FIS CRC errors received on the other host port of the AAMUX
	O-TX		The number of SATA R_ERR primitives received on the other host port indicating a
			problem with the transmitter of the AAMUX
	O-Link		The number of times the PHY has lost link on the other host port.
	O-Disp		The number of frame errors for the other host port of the AAMUX. These include: code
			error, disparity error, or realignment.
	D-RX		The number of SATA FIS CRC errors received on the device port of the AAMUX
	D-TX		The number of SATA R_ERR primitives received on the device port indicating a problem
			with the transmitter of the AAMUX.
	D-Link		The number of times the PHY has lost link on the device port.
	D-Disp		The number of frame errors for the device port of the AAMUX. These include: code error,
			disparity error, or realignment.
	SAS PHY ERRORS
	InvDW		Invalid DWORD Count - The number of invalid dwords received outside of the PHY
			reset sequence.
	RunDis		Running disparity Count - The number of dwords containing running disparity errors
			received outside of the PHY reset sequence
	LDWSYN		Loss of DWORD synchronization count - The number of times the PHY has lost
			synchronization and restarted the link reset sequence
	PHYRES		PHY Reset Problem count - The number of times the PHY reset sequence has failed.

NOTE : SATA drives have an Active/Active MUX (AAMUX) installed. Error counts are read directly from the AAMUX.
