You have two interfaces which export the same onboard interface index. There is not much udev can do here; the only option is to disable onboard interface name policy. The attributes that are used by udev are "acpi_index" and "index". Check values of these attributes for all interfaces. > Jan 03 11:30:20 nasl002b.example.com kernel: e1000e 0000:05:00.0 enp5s0: NIC > Link is Up 1000 Mbps Full Duplex, Flow Control: None > > > Apparently udev stops renaming interfaces after the first conflict. eth4 and > eth5 > have kept their names, too, even thought there wouldn't be any further > conflict: > As is obvious from the log you provided, they did not "keep" their names but were renamed.
