 1. Configuring the one Ethernet port you have for VLAN operation.
 2. https://www.amazon.com/NETGEAR-GS105Ev2-Ethernet-Lifetime-Replacement/dp/B00HGLVZLY
    $34.99 next day.

I have a several of these running multiple VLANs, and they eliminate the 
need for parallel Ethernet cables (for different networks) going to the 
same location.  Nominally 12vDC, I run mine on 13.8 from my amateur 
shack supply.

Not as convenient as being on the same board as a Pi, but not much bigger.

I think they will show the same MAC address in the Pi, and of course the 
total bandwidth is the same.

> Not sure what you are driving at, but many people suggest that an Ethernet USB adapter can be used, but the USB bus on the Pi is not designed for the kind of bandwidth needed for an Ethernet interface, hence the problem. But to answer your question: Yes, we need two physical Ethernet interfaces with separate PHYs and MAC addresses.
