Author: scottl Date: Fri Feb 20 07:40:54 2009 New Revision: 188844 URL: http://svn.freebsd.org/changeset/base/188844 Log: Tell CAM that SPI disconnect works, which in turn will let it use tags. This fixes the low "max device openings" count that has lead to poor performance in FreeBSD 7.0 and 7.1. Extra thanks goes to Mike Tancsa at Sentex for providing a debug system for this.
