Title:
  15.04: no route when connected to both WiFi and Ethernet

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce
  ===============

  1) Enable both a WiFi connection and plug into Ethernet
  2) Test your network connectivity or run `route`

  Expected results
  =============

  NetworkManager should prefer the wired connection over the WiFi
  connection, and `route` should return something like this:

  $ route
  Kernel IP routing table
  Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
  default         10.17.75.1      0.0.0.0         UG    1024   0        0 wlan0
  10.17.75.0      *               255.255.255.0   U     0      0        0 wlan0
  link-local      *               255.255.0.0     U     1000   0        0 wlan0

  (To get the above results on Vivid, I had to unplug my Ethernet.)

  Actual results
  ===========

  `route` will produce no results and your connectivity will be broken

  Work-arounds
  ===========

  As soon as you disable either the WiFi or unplug from Ethernet, you
  will again have a route and your network connectivity will work. This
  is a regression from Trusty and Utopic.
