Author: delphij
Date: Wed Jul 21 18:50:24 2010
New Revision: 210358
URL: http://svn.freebsd.org/changeset/base/210358
Log:
Apply vendor version 1.20.00.17.
This version adds support for ARC1880; additionally this version fixed
an issue where all devices on a SAS port gets offlined when any device
failed on the port [1].
Many thanks to Areca for continuing to support FreeBSD.
