[pbs-devel] [PATCH proxmox 1/1] network-api: make address field optional

[Christian Ebner]

Tested this with success on a device with wwan interface, reporting a 
link type `link/none` in `ip link show` output!

Unfortunately this does not fix the issue on a host were I have an IPv6 
tunnel set up. The link there reports as `link/sit 0.0.0.0 peer <peer-ip>`.

So it would be probably best to bundle mac address and link type ether 
in a struct or named tuple, and leave the option for other link types 
which might have different, non-mac hardware addresses.
