From d1cbfc6a59e27fecf4f2ebbc0f7d35f40d55f029 Mon Sep 17 00:00:00 2001
From: ken <ken@FreeBSD.org>

Subject: 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.

Submitted by:	Andrew Gallatin <gallatin@cs.duke.edu>

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

Verified by:    Jean-Marc Zucconi <jmz@FreeBSD.ORG>

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