svn commit: r222520 - head/sys/cam/ata

[Alexander Motin]

Author: mav
Date: Tue May 31 09:22:52 2011
New Revision: 222520
URL: http://svn.freebsd.org/changeset/base/222520

Log:
  Add quirks to hint 4K physical sector (Advanced Format) for ATA disks not
  reporting it properly (none? of known disks now).
  
  Hitachi and WDC AF disks seem could be identified more or less formally.
  For Seagate and Samsung enumerate some found models/series.
  For other disks it can be forced with kern.cam.ada.X.quirks=1 tunable.
