Subject: [PATCH 10/10] Change mobile broadband (wwan) checkbox into a
 tristate checkbox. I do not know why NM sends a wwan
 disabled signal right after we send an enable wwan
 command, the checkbox bounces for while until NM
 finally decides to enable or not the mobile broadband
 state.

The third state is "partically checked", represented by a dashed tick
mark.

BUG: 287794
