1gb full duplex cannot be set to auto-nego off?

Hi all,
I've changed eth0 to (#ethtool eth0):
Speed: 1000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on

and (#cat /etc/sysconfig/network-scripts/ifcfg-eth):
ETHTOOL_OPTS="autoneg off speed 1000 duplex full"

But, even after restarting the service and rebooting the server, the ouput of ethtool eth0 is still showing - Auto-negotiation: on.

Any idea why it is behaving that way..?

Thank you for all your help..

NAME
ifcfg-wireless - wireless LAN network interface configuration SYNOPSIS
/etc/sysconfig/network/ifcfg-wlan-* /etc/sysconfig/network/ifcfg-type-wlan GENERAL
Wireless networks need some additional configuration data compared to ethernet ones. Therefore additional variables for ifcfg files were introduced. All wireless LAN specific variables are described in the ifcfg template file /etc/sysconfig/network/ifcfg.template. It is pos- sible to configure more than one wireless network accepted for association. To achieve this add suffix _1 to all wireless variables for the second network, _2 for the this, and so on. Example: WIRELESS_ESSID_1="second_net" You can have up to ten wireless networks configured. Some wireless variables are not applicable to a single wireless network but are global to the interface. The description of the variable points this out. BUGS
