Easier service speed parameter change for network interfaces

7. You have to remove the service from monitoring for each changed port, then do a full rescan, then add the newly rediscovered services that now have a 10Gbps speed parameter.

There is already a 1 click solution available if you have only the changed ports to rediscover.

And there are no vanished services on this device you want to keep.
