[Peter Grehan]

Author: grehan

New Revision: 288826
URL: https://svnweb.freebsd.org/changeset/base/288826

Log:
  Clean up some harmless unimplemented-command warning messages.
  
  - Don't advertize trusted-computing capability in the Identify page.
    This prevents Windows from issuing a TRUSTED_RECEIVE_DMA command.
  - Windows will send down SMART and SECURITY_FREEZE_LOCK
     even though smart and security capabilities were not advertized.
     Send back a silent abort.
