Sorry yes I forgot to mention this. As you can see in the output below
there is no difference between ifconfig -A in the problematic and working
case except the signal strength.
I also just realized that I made a mistake in Scenario 1. To get
iwn0 to work in this trunk setup, I need to unplug the cable and _then_
run sh /etc/netstart.
1) pinging via em0 works
2) switch to iwn0, ping doesn't work <-- problem
3) sh /etc/netstart
4) pinging via iwn0 works
