Detect bridged network adapters when running from VM
As explained in #7695 (closed), when running in a VM with a bridged network adapter, the notion of MAC spoofing doesn’t make much sense and doesn’t work. It would be great to detect that kind of setup and do something smart in Tails Greeter upfront.
The first step is to check whether it is possible to know from inside the VM that it is using a bridged adapter.
