PVE 6 to 7 BCM57412 devices name change

[Eneko Lacunza]

Hi all,

I have noticed that when upgrading from PVE 6.4 to 7.2, BCM57412 network 
devices change name, i.e.:

ens2f0np0 -> enp101s0f0np0

Devices are seen like:
65:00.0 Ethernet controller: Broadcom Inc. and subsidiaries BCM57412 
NetXtreme-E 10Gb RDMA Ethernet Controller (rev 01)
65:00.1 Ethernet controller: Broadcom Inc. and subsidiaries BCM57412 
NetXtreme-E 10Gb RDMA Ethernet Controller (rev 01)

I have seen this in 3 different servers until now (all Dell PowerEdge).

This can be an issue if upgrading remotely (I was today, had to resort 
to  iDRAC virtual console).

Has anyone seen this? Is there a way to know what the new name will be, 
so that /etc/network/interfaces can be changed accordingly?

Shall I suggest a change in 6to7 wiki?

Thanks!
