SUMMARY

I should be able to edit "Parent interface" for DSL connections. I'm using Linux to debug-skip my ISP (Primus)'s router, and the PPPoE must be wrapped by VLAN 40.

STEPS TO REPRODUCE
1. `kcmshell6 kcm_networkmanagement`
2. Click the `+` icon
3. Click "DSL"

OBSERVED RESULT
There's no "Parent interface" field

EXPECTED RESULT
It should be like `nm-connection-editor`. With the same steps, I immediately see a "Parent interface" dropdown.
