  28  *  In this version, sg_tablesize now defaults to WD7000_SG, and will
  29  *  be set to SG_NONE for older boards.  This is the reverse of the
  30  *  previous default, and was changed so that the driver-level
  31  *  Scsi_Host_Template would reflect the driver's support for scatter/
  32  *  gather.
  33  *
  34  *  Also, it has been reported that boards at Revision 6 support scatter/
  35  *  gather, so the new definition of an "older" board has been changed
  36  *  accordingly.
