 | |
|   The SendData function sends a security protocol command containing the payload
 | |
|   PayloadBuffer to the given MediaId. The security protocol command sent is
 | |
|   defined by SecurityProtocolId and contains the security protocol specific data
 | |
|   SecurityProtocolSpecificData. If the underlying protocol command requires a
 | |
|   specific padding for the command payload, the SendData function shall add padding
 | |
|   bytes to the command payload to satisfy the padding requirements.
 | |
| 
 | |
|   For devices supporting the SCSI command set, the security protocol command is sent
 | |
|   using the SECURITY PROTOCOL OUT command defined in SPC-4.

|   If PayloadBuffer is NULL and PayloadBufferSize is non-zero, the function shall
 | |
|   return EFI_INVALID_PARAMETER.

 | |
|   If the given MediaId does not support security protocol commands, the function
 | |
|   shall return EFI_UNSUPPORTED. If there is no media in the device, the function

 | |
|   device, the function returns EFI_MEDIA_CHANGED.
