- * 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.
