Hi there,

Now Network Manager(NM) is able to manage the devices with the following changes.
Change the contents of the file /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf to
----------------------------------------------------
[keyfile]
unmanaged-devices=none
----------------------------------------------------

from
----------------------------------------------------
[keyfile]
unmanaged-devices=*,except:type:wifi,except:type:wwan
----------------------------------------------------

and restart NM(service network-manager restart) did the trick.

Why it didn't work earlier:
We added interfaces to the file /etc/network/interfaces.
So NM is not able to manage the interfaces updated in the said file.

When we removed the interfaces from the above file, It started working.

Is this approach correct ??
