All: Thank you for all your reply and the useful advice.
There is progress on this issue In logs I find this: Jun 17 02:46:02 intel-x86-64 systemd-udevd[252]: Skipping overridden file '/lib/udev/rules.d/80-net-setup-link.rules'. So I find: root@intel-x86-64:~# ls -l /etc/udev/rules.d/80-net-setup-link.rules lrwxrwxrwx 1 root root 9 Mar 9 2018 /etc/udev/rules.d/80-net-setup-link.rules -> /dev/null I remove the file and it works. I don't know why and where this file /etc/udev/rules.d/80-net-setup-link.rules from.

NamePolicy is empty by default and only one .link file is applied. There should be nothing to clear unless I miss something. And any drop-in is processed after the file itself so it is impossible to clear settings in drop-ins, correct?
