[PVE-User] network interfaces renamed after update to proxmox6

[Roland @web.de]

hello,

the following network interfaces  got lost after update to proxmox6

enp4s0f0
enp4s0f1
enp5s0f0
enp5s0f1

apparently , they got renamed to

ens7f0
ens7f1
rename2
rename7

Does anybody know the reason for that or how to fix it or to get to 
"stable ethernet interface naming scheme" ?

network config, configured with proxmox 5.4 - still existant with proxmox6
