We always set the port speed and duplex, only if the other side
doesn't support that (for example unmanaged media converters) we leave
it to auto. We had cases in the past where devices got reloaded and
when came back didn't negotiate properly (most often stuck in
half-duplex). Those issues are sometimes quite difficult to spot. So
we settled on hard settings.
