Is it possible for Smoothieboard at a hardware level to manage its Ethernet link speed, and if so can this be exposed to the user for control?

I have a Smoothieware 5x board, and I am also an amateur radio operator who is finally getting serious about hunting down persistent radio frequency interference (RFI) in my house. The Smoothieboard emits a fairly strong pair of carriers across a bunch of harmonic frequencies and I have multiple antennas picking up these RFI in the 14MHz and 28MHz ranges. Smoothieboard is not the only culprit, I also have a Cisco Linksys VoIP appliance and one of the many rebranded Chinese Security DVR systems -- both these also emit the exact same frequencies. No amount of toroid windings is taming the RFI from these Ethernet cables.

But! if I put a managed switch into the picture and force these devices' switch ports from Auto negotiate down to always run 10baseT (10mbit) full duplex, the RFI disappears. All these devices' (Smoothie included) use cases are served just fine at 10mbps link speed. Unfortunately I only have one managed switch and I need it elsewhere. Smoothieware devs, can you help clean up this ham's radio spectrum with a software fix? (Clarify: RFI is to be expected during 3D printer operation, but not 24/7 idle Ethernet noise)

I just updated/upgraded my UI and fixed some issues. Could you update your repo?
