Modified files:
sys/cam cam_xpt.c
Log:
Add several quirks:
Western Digital Enterprise drives have sorry performance (1.5MB/sec versus
8MB/sec) when doing tagged queueing. Disable tagged queueing for them.

Some Sony CDROM drives don't like it when we probe more than one LUN.

Some Sony CD-R's don't like multi-LUN probing either.
