  34  *  In this version, sg_tablesize now defaults to WD7000_SG, and will
  35  *  be set to SG_NONE for older boards.  This is the reverse of the
  36  *  previous default, and was changed so that the driver-level
  37  *  Scsi_Host_Template would reflect the driver's support for scatter/
  38  *  gather.
  39  *
  40  *  Also, it has been reported that boards at Revision 6 support scatter/
  41  *  gather, so the new definition of an "older" board has been changed
  42  *  accordingly.
