Subject: [RHEL5.1 PATCH] s2io: update to driver version 2.0.25.1
Date: Mon, 13 Aug 2007 15:10:50 -0400
Bugzilla: 223033
Message-Id: <20070813191049.GE19875@gospo.rdu.redhat.com>
Changelog: [net] s2io: update to driver version 2.0.25.1
This is an update to the s2io driver as requested by Neterion.
Apparently this is needed by some vendors who will be shipping Neterion
Xframe-II cards.
This will resolve BZ 223033.
