bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=4011 Currently AHCI driver will try to retry all failed packets regardless of the failure cause. This is a problem in password unlock flow where number of password retries is tracked by the device. If user passes a wrong password Ahci driver will try to send the wrong password multiple times which will exhaust number of password retries and force the user to restart the machine. This commit introduces a logic to check for the cause of packet failure and only retry packets which failed due to transient conditions on the link. With this patch only packets for which CRC error is flagged are retried.
