Subject: [net] NetXen driver update to 3.4.18
Message-id: 4890CB8B.4040709@redhat.com
O-Subject: [PATCH RHEL 5.3] NetXen driver update to 3.4.18
Bugzilla: 443619
RH-Acked-by: Jeff Garzik <jgarzik@redhat.com>
Bugzilla 443619
This is a back port of the upstream NetXen driver as of 6/13/08. Updating the driver
was the best way to take in the portions of the upstream driver that are needed to resolve
bugzilla 443619. Patch was originally created by Dhananjay Phadke.
This has been tested at IBM and has been working. There are no longer any messages about the
Watchdog timer or sleeping function called from invalid context.
Netperf and ping tests confirmed that the driver still works properly after the patch.
Brew: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=1414704
Back port of following commits from netdev upstream:
