Initial fix seems to work on arale. I'm able to switch back and forth
between Wi-Fi and mobile-data, and nm no longer attempts to manage the
ccmni* devices.

Title:
Problems switching between WiFi and Mobile Data on MTK-based phones
Status in network-manager package in Ubuntu:
In Progress
Bug description:
On recent vivid images running on phones with MTK modems ( arale,
krillin ) switching between WiFi and mobile-data and back leads to
broken networking where neither device ( WiFi or WWAN ) will establish
a network connection.
It appears that the new version of network-manager in vivid (
0.9.10-4ubuntu6 ) is incorrectly attempting to manage the devices
created by rild when mobile-data connections are established.
For instance, on krillin running RTM, 'nmcli -d' reports the following
networking devices:
% nmcli d
wlan0 wifi disconnected
ril_0 gsm connected
ril_1 gsm disconnected
On the same device running vivid, an extra device which should be
unmanaged is listed:
% nmcli d
ril_0 gsm connected /310410786147829/context2
ccmni0 wifi connected ccmni0
wlan0 wifi disconnected --
ril_1 gsm unavailable --
ccmni1 wifi unmanaged
Note that ccmni0 is listed as a wifi device, with a status of
connected whereas ccmni1 is listed as unmanaged.
If you look at syslog, you'll see a two log messages output after
ril_0 is activated which show network-manager detecting a change in
ccmni0 and deciding it should become managed:
