Ah, interesting. Note that you don't actually need to set any
dictionary entries if you aren't going to put anything in them. So you
don't need to specify addresses, routes, or addresses. You also don't
actually need to set the 'security' parameter either (as of NM 1.0?)
since NM will infer that automatically if you pass a 'wireless-
securitry' setting.
