Routine Description:
TODO: Add function description
Sends a SCSI Request Packet to the SCSI Controller for execution.
Arguments:
This - TODO: add argument description
CommandPacket - TODO: add argument description
Event - TODO: add argument description
This - Protocol instance pointer.
Packet - The SCSI request packet to send to the SCSI
Controller specified by the device handle.
Event - If the SCSI bus where the SCSI device is attached
does not support non-blocking I/O, then Event is
ignored, and blocking I/O is performed.
If Event is NULL, then blocking I/O is performed.
If Event is not NULL and non-blocking I/O is
supported, then non-blocking I/O is performed,
and Event will be signaled when the SCSI Request
Packet completes.
Returns:
TODO: add return values
EFI_SUCCESS - The SCSI Request Packet was sent by the host
successfully, and TransferLength bytes were
transferred to/from DataBuffer.See
HostAdapterStatus, TargetStatus,
SenseDataLength, and SenseData in that order
for additional status information.
EFI_BAD_BUFFER_SIZE - The SCSI Request Packet was executed,
but the entire DataBuffer could not be transferred.
The actual number of bytes transferred is returned
in TransferLength. See HostAdapterStatus,
TargetStatus, SenseDataLength, and SenseData in
that order for additional status information.
EFI_NOT_READY - The SCSI Request Packet could not be sent because
there are too many SCSI Command Packets already
queued.The caller may retry again later.
EFI_DEVICE_ERROR - A device error occurred while attempting to send
the SCSI Request Packet. See HostAdapterStatus,
TargetStatus, SenseDataLength, and SenseData in
that order for additional status information.
EFI_INVALID_PARAMETER - The contents of CommandPacket are invalid.
The SCSI Request Packet was not sent, so no
additional status information is available.
EFI_UNSUPPORTED - The command described by the SCSI Request Packet
is not supported by the SCSI initiator(i.e., SCSI
Host Controller). The SCSI Request Packet was not
sent, so no additional status information is
available.
EFI_TIMEOUT - A timeout occurred while waiting for the SCSI
Request Packet to execute. See HostAdapterStatus,
TargetStatus, SenseDataLength, and SenseData in
that order for additional status information.
