Hello,
in f11 I had a line into /etc/rc.d/rc.local to force speed/duplex/autoneg:
/sbin/ethtool -s eth0 speed 100 duplex full autoneg off >> /tmp/ethtool.log 2>&1
In F12 I see that this setting is not maintained.
After I log in in Gnome I see that:
[r...@tekkaman ~]# ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Half
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Current message level: 0x000000ff (255)
Link detected: yes
The log file has timestamp of my boot time, so that I know it was
actually executed.
If I run it manually it succeeds and I get now:
Advertised link modes: Not reported
Advertised auto-negotiation: No
Speed: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: off
Supports Wake-on: g
Wake-on: d
Current message level: 0x000000ff (255)
Link detected: yes
but after some minutes I get again:
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Half
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Current message level: 0x000000ff (255)
Link detected: yes
So there is something external that manage this kind of changes.
Some questions:
- network guys say me that switch port is fixed at 100/full (it is a
gigabit ethernet) so, if this is true, even in autoneg there is an
error in getting settings
- what is the component that changes the settings? I walked through NM
applet to edit connections but I don't see any parameter....

with dmesg I get these messages:

So I have many link down messages and (apparently) renegotiation tthat
then gives 100/half
Any suggestions???
BTW I have libvirtd started but no vm created
Thanks in advance,
Gianluca
