Description Mauricio Cavalcanti 2004-12-07 15:30:32 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET 
CLR 1.1.4322)

Description of problem:
I have many DL-360-G4 using ETHTOOL_OPTS in ifcfg-eth0, forcing 100 
Mbps, full duplex and autoneg off, but when I put the same 
ETHTOOL_OPTS in DL-380-G4 (tg3), I have 100 Mbps, half duplex and 
autoneg off. It seems it´s not reading ETHTOOL_OPTS.

In DL-380-G4, when i run "ifcfg eth0 down", ethtool command shows me 
100Mbps... if NIC is down and "ifconfig" command don´t show me any 
about eth0 (only "lo"), how it "ethtool" command shows me 100Mbps and 
more? In DL-360-G4, it works fine.

I put ethtool comand in rc.local as workaround, and it´s working as I 
want (100 Mbps, full duplex and autoneg off).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.set ETHTOOL_OPTS in ifcfg-eth0 with speed 100 duplex full autoneg 
2.reboot or network restart;
3.run "ethtool eth0"... the answer is "speed 100 duplex half autoneg 
off", not full duplex;
4.if I run or put "ethtool -s eth0 speed 100 duplex full autoneg off" 
in rc.local, it works fine.

Actual Results:  run "ethtool eth0" and the answer is "speed 100 
duplex half autoneg off", not full duplex, even when eth0 is down !

Expected Results:  ETHTOOL_OPTS must work if I put in ifcfg-eth0 and 
ethtool cannot answer "speed 100 duplex half autoneg off" if NIC eth0 
is down.

Are you using the exact same network config in both cases?
