Author: mav Date: Sat Jun 9 07:43:11 2012 New Revision: 236786 URL: http://svn.freebsd.org/changeset/base/236786 Log: MFC r236437: Rewrite enabling NCQ for SATA devices in a way more alike to SCSI TCQ. This allows to control it with `camcontrol negotiate adaX -T (en|dis)able` on the fly, same as for SCSI devices. Sponsored by: iXsystems, Inc.
