Yes, KNetworkManager, may that be a problem?

I don't have the lines discussed in the thread, probably because I use the 
KNetworkManager:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0
up ethtool -K eth0 tx off

The last line doesn't change the behavior, but I found that somewhere in the 
net to help out of networking troubles with some newer cards...

That's fixed for me...
