Is there any way that I can make networkmanager to assign some unique
names or device derrived name instead of `Auto Ethernet` so that we can
avoid the names conflict?

After I've upgraded to Ubuntu Vivid which uses systemd(though I'm not
sure if it's directly related or it's just a bug / regression of
network-manager) both of my mobile broadband devices get the "Auth
Ethernet" name and are unable to get connected simultaneously.

I can temporarry fix it using  `nmcli con add type ethernet con-name my-
office ifname ens3` but I would rather like to have network-manager
handle this automatically (i.e. assign a random / unique conn name).

Use case:

I have two broadband USB devices and I need to connect to both of them. The issue is that NetworkManager displays them both as `Auto Ethernet` (duplicate in the network manager applet) and when I try to connect to the second network it errors out ``(32) Connection 'Auto Ethernet' is already active on enp0s20u``. 
  When I try to "edit" the connections it displays only one `Auto Ethernet` connection. 
  
 `/etc/NetworkManager/system-connections` also lists only one `Auto Ethernet`

Title:
  Network Manager Applet has duplicate entry changing IPv4 Method

Status in Network Manager GNOME Applet:
  New
Status in network-manager-applet package in Ubuntu:
  Triaged

Bug description:
  1) lsb_release -rd
  Description:	Ubuntu Vivid Vervet (development branch)
  Release:	15.04

  2) apt-cache policy network-manager-gnome
  network-manager-gnome:
    Installed: 0.9.8.8-0ubuntu4.3
    Candidate: 0.9.8.8-0ubuntu4.3
    Version table:

  3) What is expected to happen in a new Vivid virtualbox guest is one
  clicks in vbox File > Preferences > Network > Host-only Networks >
  click plus icon to Add host-only network > IPv4 Address: 192.168.56.1
  > IPv4 Network Mask: 255.255.255.0 > IPv6 Address:
  fe80:0000:0000:0000:0800:27ff:fe00:0000 > IPv6 Network Mask Length: 64
  > tab DHCP Server > uncheck Enable Server > OK >  highlight Vivid
  guest > Settings > Network > tab Adapter 1 > check Enable Network
  Adapter > Attached to: Host-only Adapter (leave defaults) > tab
  Adapter 2 > check Enable Network Adapter > Attached to: NAT (leave all
  other settings as default) > OK.

  Start the Vivd guest and login > top right of screen secondary click
  Network Manager icon in the taskbar > Settings... > highlight WIred
  Connection 1 > Edit > tab IPv4 Settings > button Add > Address
  192.168.56.3 > Netmask 255.255.255.0 > Gateway 192.168.56.1 > Save >
  click on the Network Manager icon in the taskbar and there should only
  be one entry for each interface.

  4) What happens instead is there are two entries for Wired Connection 2, one that's connected, one that's disconnected, as per the attached screenshot:
  https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1402094/+attachment/4279934/+files/screenshot.png

  If one were to reverse the order of the adapters in vbox, one would
  see two entries for Wired Connection 2 in Network Connections.

  This is a regression as this was not reproducible in Precise 12.04.5.
