>Release:        NetBSD 1.5W, June 29, 2001
>Organization:
Zembu Labs, Inc.
>Environment:
	Any platform which has a bus_dmamap_sync() which actually
	does something.

>Description:
	The Tigon (`ti') driver does not use bus_dmamap_sync() to
	synchronize DMA mappings for the incoming/outgoing packets,
	or for the host->Tigon communication data structures stored
	in host memory.

>How-To-Repeat:
	Code inspection.

>Fix:
	Add bus_dmamap_sync() calls in the appropriate places.
	(Maybe it's easier to just rewrite the driver from scratch?)
