This reverts commit 0f5a529217.
As discussed in https://github.com/systemd/systemd/issues/33104,
that patch caused problems in Debian which has a udev drop-in with
[Match]
Path=*-usb-*
[Link]
NamePolicy=mac
The rename fails:
eth0: Policy *mac* yields "enx00*".
eth0: /usr/lib/udev/rules.d/80-net-setup-link.rules:11 NAME 'enx00*'
eth0: /usr/lib/udev/rules.d/99-systemd.rules:69 RUN '/usr/lib/systemd/systemd-sysctl --prefix=/net/ipv4/conf/$name --prefix=/net/ipv4/neigh/$
eth0: sd-device: Created database file '/run/udev/data/n9' for '/devices/pci0000:00/0000:00:1c.4/0000:02:00.0/0000:03:01.0/0000:05:00.0/0000:
eth0: Failed to rename network interface 9 from 'eth0' to 'enx00*': File exists
eth0: sd-device: Created database file '/run/udev/data/n9' for '/devices/pci0000:00/0000:00:1c.4/0000:02:00.0/0000:03:01.0/0000:05:00.0/0000:
eth0: Failed to process device, ignoring: File exists
Two network interfaces have the same MAC and it's not marked NET_ADDR_STOLEN.
In this case the conflict is very visible because it causes the rename to fail,
but it would also occur in other cases, for alternative names.
A patch has been submitted for r8152 to properly set NET_ADDR_STOLEN:

Let's revert this now to avoid a regression. We can try again after the kernel
issue is resolved.
