so ConnMan is suppose to ignore all interfaces with DEVTYPE=wwan. These
will be picked up by oFono.
Just make sure oFono detects your HSO device. There is a udev rule
required to do so at the moment. And then ConnMan will see the HSO
device through oFono. I have tested it with an older iCON card.
The actual interface name is given via D-Bus to ConnMan. So it doesn't
really matter that ConnMan ignores ARPHRD_NONE.
