[ 21/73] 3c59x: shorten timer period for slave devices

[Greg KH]

3.0-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.
