◆ LsiScsiCheckRequest()

STATIC EFI_STATUS LsiScsiCheckRequest	(	IN LSI_SCSI_DEV *	Dev,
		IN UINT8	Target,
		IN UINT64	Lun,
		IN OUT EFI_EXT_SCSI_PASS_THRU_SCSI_REQUEST_PACKET *	Packet
	)

Check the request packet from the Extended SCSI Pass Thru Protocol. The request packet is modified, to be forwarded outwards by LsiScsiPassThru(), if invalid or unsupported parameters are detected.

Parameters

[in]	Dev	The LSI 53C895A SCSI device the packet targets.
[in]	Target	The SCSI target controlled by the LSI 53C895A SCSI device.
[in]	Lun	The Logical Unit Number under the SCSI target.
[in,out]	Packet	The Extended SCSI Pass Thru Protocol packet.

Return values

EFI_SUCCESS The Extended SCSI Pass Thru Protocol packet was valid.

Returns: Otherwise, invalid or unsupported parameters were detected. Status codes are meant for direct forwarding by the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() implementation.
