Table 127 Abort NCQ Queue Subcommand (0h)
Normal Outputs
If a supported Abort Type parameter is specified, then the device indicates success, even if the command results in
no commands being aborted.
When an Abort NCQ Queue command completes successfully, a Set Device Bits FIS is sent to the host to complete
the Abort subcommand and commands that were aborted as a consequence of the Abort subcommand by setting
the ACT bits for those commands to one. This SDB FIS may also indicate other completed commands.
Error Outputs
The device returns command aborted if:
a) NCQ is disabled and an Abort NCQ Queue command is issued to the device;
b) the value of the TTAG field equals the value of the TAG field;
c) the value of the TTAG field is an invalid TAG number; or
d) an unsupported Abort type parameter is specified.
