I have a question about ACA.  If a SCSI-3 target detects a parity
error during the command phase and returns check condition status,
how does the target know what ACA processing the initiator requested?
The target cannot rely on the NACA bit in the control field if the parity
error was on that byte or on the opcode byte.

ACA only works if both initiator and target know that ACA is active.
