+# NCR5380-based "Sun SCSI 3" VME SCSI controller.
+# This driver has several flags which may be enabled by OR'ing
+# the values and using the "flags" directive.
+# Valid flags are:
+#
+#	0x01		Use DMA (may be polled)
+#	0x02		Use DMA completion interrupts
+#	0x04		Allow disconnect/reselect
+#
+# E.g. the following would enable DMA, interrupts, and reselect:

+# By default, DMA is enabled in the driver.
