Message-ID: <20091123080203.GA7778@serverengines.com>
Date: Mon, 23 Nov 2009 13:32:03 +0530
From: Sathya Perla <sathyap@...verengines.com>
To: netdev <netdev@...r.kernel.org>
Subject: [net-next-2.6 PATCH 3/5] be2net: Issue fw_init/clean cmds to fw
These cmds are issued to the fw in probe/resume and remove/suspend
paths to help fw execute some initialization and cleanup code.
This change needed the be_hw_up() code to be refactored as be_get_config().
Signed-off-by: Sathya Perla <sathyap@...verengines.com>
