It never hurts to be pedantic with tagging! Yes there was a tip about mapping a roundabout as the most major road connecting to it, i.e. directly connecting to or across it. So in your example it would almost certainly be highway=motorway_link. Though just to confuse things again slightly, I would normally consider a primary or trunk road passing across the roundabout to be "above" a motorway link and therefore map the roundabout as primary or trunk - I don't know if that is standard practice.
