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.
