From f8320f059296eb8cab6e2429c7ec79b43d42cf42 Mon Sep 17 00:00:00 2001 From: Rajesh Borundia Date: Wed, 14 Jul 2010 17:55:35 -0700 Subject: netxen: fix for kdump When the crash kernel is loaded after crash, the device is in unknown state. So reset the device contexts prior to its creation in case of kdump, depending upon kernel parameter reset_devices. Signed-off-by: Rajesh Borundia Signed-off-by: David S.
