[Bug 1574347] Re: [SRU]network-manager

[Aron Xu]

** Description changed:

- Issue is in Ubuntu 16.04 LTS amd64 version.
+ [Impact]
+ NM needs to re-read the DEVTYPE after the device name changed, an example is that WiFi network list disappears from network manager applet
  
  Steps to reproduce: -
  
  1. Connect to a WiFi AP.
  2. Switch off the AP OR switch off the wifi in the computer.
  3. Switch point (2) back on.
  4. The network will get connected to the AP it was connected to in point (1).
  
  Problems:-
  
  1. The network manager applet does not show the list of WiFI APs it can find.
  2. The network manager applet does not the name of the AP to which it is connected
  3. The icon of the applet shows two vertical arrows in opposite direction - the wired connection symbol and NOT the wifi connected icon.
  
- 
  Temporary Workaround:-
  Log out and again log back in.
  
- Please solve this issue asap.

+ After upgrading to the new version, the repeating the above steps should
+ give expected behavior.
+ 
+ [Regression Potential]
+ Potential of causing regression is relatively small for a one line change to re-read a value to be known.
