 OK that answers the question and makes sense now. Could I suggest
 adding the following script fragment. This would avoid headaches for
 people who run Raspberry Pi 3 without other USB devices plugged in.
 
 /etc/rc.d/network:
 
 network_start()
 {
 	# Workaround for PR#55317
         local hw_model i
         hw_model=`sysctl -n hw.model | grep '^raspberrypi,3'`
         if [ -n "$hw_model" ]
         then
                 echo "Detected Raspberry Pi 3 hardware model"
                 echo "Waiting for USB ethernet device to attach..."
 
                 # Wait for up to 5 seconds before giving up
                 for i in 1 2 3 4 5
                 do
                         ifconfig mue0 >/dev/null 2>&1 && break
                         sleep 1
                 done
         fi
 
 ...
 }
