The 'dhcp-client-service' fail to start when a non-libre network 
interface (here 148f:3070) is plugged-in even though there is an libre 
networking interface (here 01:00.0) available.
Removing the non-libre networking interface from the system allow 
'dhcp-client-service' to start correctly on the libre networking 
interface.

I think the service shouldn't crash when there is an non-libre network 
interface connected, it should just skip it and maybe throw an error 
message. Allowing to specify the network interfaces on which 
'dhcp-client-service' should run can also somewhat resolve the issue.
