The proper way to do that is to configure autonegotiation and specify
what to advertise.  Turning off autonegotiation is stupid.

If the port advertises "I can only do 10Mbit" then that is the speed
the ports will negotiate at.  Any decent managed switch can do that.

So there is no excuse for what they are doing other than incompetence.
