How to connect two NHI350-AM4 GbE controllers through a MUX to the magnetics?

[Engenia]

 I want to connect two NHI350-AM4 GbE controllers through a MUX to the magnetics. I have seen lots of loading and biasing circuits for various controller/mux combinations, but I can't see why the NHI350-AM would need anything other than direct connection as per the circuit below.

Is this circuit enough?

Hello @Maecenas_INTEL, I appreciate your taking the trouble to reply, but pointing me to a document that I can not access is not that helpful. It's even more galling that I tried to gain privileged access several months ago and was presented with stony silence.

I have just now made a second attempt.

I don't want to appear ungrateful, I truly am appreciative of any help that is offered, but if you know the answer to my question would you mind divulging it?

If you don't, then fair enough, please accept my apologies. (You can tell I'm somewhat frustrated.)
