I was having the same issue and finally resolved to make sure that my "consistent" ethernet device was named eth0.  I did that with
the following line in /etc/udev/rules.d/70-my-net-names.rules:

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="c8:0a:a9:b1:46:c2", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth0"

Thereby forcing my device with that mac address to have name eth0.  dmesg shows udev/systemd changing this:

[    3.975997] systemd-udevd[232]: renamed network interface eth0 to p6p1
[   21.108994] systemd-udevd[421]: renamed network interface p6p1 to eth0

YMMV.
