This is ethtool output[1]

the only difference compared to another server where I don't have these
problems while using an ADSL line at 200Mbit/s is:
        Link partner advertised pause frame use: Symmetric Receive-only

On other server this setting is 
	Link partner advertised pause frame use: No

On both server the speed value is: 
	Speed: 1000Mb/s

Yes, also I think so, but I cannot how to solve this problem.

Many thanks
