New Revision: 293865
URL: https://svnweb.freebsd.org/changeset/base/293865

Log:
  MFC: r287473
    Add the new sesutil(8) utility for managing SCSI Enclosure Services (SES) device.
  
  MFC: r287493
    Fix iteration bug
  
  MFC: r287485, r287494, r287992
    Please the angry gcc 4.2 gods
  
  MFC: r287988
    Improve and expand sesutil(8)
  
    Return an error if no matching device is found
    Locate can address a slot, in addition to a drive
    Added fault, similar to locate but blinks a different LED
    Added the map command, lists all devices connected to the SES controller
    Added the status command, overall status of the SES controller
  
  MFC: r292092
    sesutil: fix map not printing the status of the LED device in an array
  
  MFC: r292093
    sesutil: pass the correct element type when printing the SES map
  
  MFC: r292121
    sesutil: Add extra information specific to some SES devices to sesutil map
  
  MFC: r292122
    Fix sesutil locate when a sesid is passed to locate command
  
  MFC: r292262
    Show the enclosure name and id in sesutil map
