Description

It looks like NetworkManager configures dhclient to send some MAC address this way. We should make sure that if it’s the case, we’re not sending the device’s permanent MAC address.

I’ve checked tcpdump traces with wireshard, for Tails 2.5 and feature/stretch, and I could not spot dhcp-client-id being sent. This matches my understanding of the NM documentation, that suggests that nothing should be sent unless the dhcp-client-id setting is explicitly set.
