svn commit: r233996 - in stable/8/sys: dev/mpt i386/conf

New Revision: 233996
URL: http://svn.freebsd.org/changeset/base/233996

Log:
  MFC: r233827
  
  Fix probing of SAS1068E with a device ID of 0x0059 after r232411 (MFC'ed
  to stable/8 in r232563).
  Reported by: infofarmer
  
  MFC: r233886
  
  Refine r233827; as it turns out, controllers with a device ID of 0x0059
  can be upgraded to MegaRAID mode, in which case mfi(4) should attach to
  these based on the sub-vendor and -device ID instead (not currently done).
  Therefore, let mpt_pci_probe() return BUS_PROBE_LOW_PRIORITY.
  While it, let mpt_pci_probe() return BUS_PROBE_DEFAULT instead of 0 in
  the default case.
