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