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