PVE 6 to 7 BCM57412 devices name change

[Bastian Sebode]

Hi Eneko,

I had the same issue when doing that upgrade on a cluster. On the first 
node I noticed the problem and fixed it over the virtual console. After 
that I noted the changes and right before the reboot of the following 
nodes I replaced the occurrences in /etc/network/interfaces accordingly 
to have a functional system after the reboot.

Unfortunately I'm not aware of how you could know these changes prior 
updating/rebooting the first node or single server.

Peace
Bastian
