[ 20/72] 3c59x: shorten timer period for slave devices
From: Greg KH

3.2-stable review patch. If anyone has any objections, please let me know.

From: Eric Dumazet <eric.dumazet@xxxxxxxxx>
[ Upstream commit 3013dc0cceb9baaf25d5624034eeaa259bf99004 ]
Jean Delvare reported bonding on top of 3c59x adapters was not detecting
network cable removal fast enough.
3c59x indeed uses a 60 seconds timer to check link status if carrier is
on, and 5 seconds if carrier is off.
This patch reduces timer period to 5 seconds if device is a bonding
slave.
