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