Remove inheritance of unmanaged condition from the parent device, on all devices
It is not possible to configure a VLAN interface on unmanaged NIC. This forces users who only want to create a VLAN interface to take ownership over possibly shared underlying NIC.
In OpenShift, the SR-IOV operator is currently not using NetworkManager to configure VFs. When it starts working with a NIC, it explicitly makes it unmanaged. Then, users cannot create a VLAN interface on PFs managed by the operator.
One of the commits here eliminates this issue by allowing configuring VLAN on an interface without requesting it to be managed by NetworkManager.
The behavior of inheriting unmanaged condition from the parent was removed from all devices with this Merge Request.
