[patch 24/29] drivers/net: Call netif_carrier_off at the end of the probe

From: Greg KH
Date: Thu Mar 10 2011 - 18:59:17 EST


2.6.37-stable review patch. If anyone has any objections, please let us know.

------------------

From: Ivan Vecera <ivecera@xxxxxxxxxx>

commit 0d672e9f8ac320c6d1ea9103db6df7f99ea20361 upstream.

Without calling of netif_carrier_off at the end of the probe the operstate
is unknown when the device is initially opened. By default the carrier is
on so when the device is opened and netif_carrier_on is called the link
watch event is not fired and operstate remains zero (unknown).

This patch fixes this behavior in forcedeth and r8169.
