1225 using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
1226 is non-zero.

1228 If the PayloadBufferSize is zero, the security protocol command is sent using the
1229 Trusted Non-Data command defined in ATA8-ACS.

1244 shall return EFI_TIMEOUT.

1252 @param[in] Timeout The timeout, in 100ns units, to use for the execution
1253 of the security protocol command. A Timeout value of 0
1254 means that this function will wait indefinitely for the
1255 security protocol command to execute. If Timeout is greater
1256 than zero, then this function will return EFI_TIMEOUT
1257 if the time required to execute the receive data command
1258 is greater than Timeout.
