Ok, as I supposed.

There was a problem on older gigabit switches and for historical
reasons was set up this way yet. Now they are on new ones and I asked
them to put the switch port to autoneg.
OK now for the speed part. I get 100/full after autoneg at boot.

But when I start for example an scp session of big files (around some
tenths of megabytes) from/to my pc, I get many link down messages.....
The transfer begins at 9.7MB/s and then continuously decreases at
about 7 and also 5 MB/s.....

See below my /var/log/messages after reboot at about 09.30 this morning.
For example at 10:23 and 11:05 I started scp sessions (single file of
about 2.5Gb)
