svn commit: r201222 - head/sys/dev/siis

[Alexander Motin]

Author: mav
Date: Tue Dec 29 21:49:11 2009
New Revision: 201222
URL: http://svn.freebsd.org/changeset/base/201222

Log:
  Usually these controllers are able to automatically decode command code to
  get required command protocol. But they have no idea about new commands,
  such as DATA SET MANAGEMENT (TRIM). As soon as this info any way provided
  by CAM, give controller specific instructions.
