[pve-devel] [PATCH] run-env: fallback to all zero mac for interfaces without

[Christian Ebner]

The installer assumes to have a valid mac address for all interfaces
as provided by the runtime env json file. Deserialization will fail
if this is not the case.

In some cases, the interface might however not provide a valid MAC
address, for example the WWAN module without any SIM installed on
some laptops.

Fix this by defaulting to an all zero MAC address if non is detected.

Please note: Untested, but I can test it based on an iso installer on
affected hardware
