Could someone point me to the commit that removed support for assigning
"ethX" names based on MAC addresses?

Alternately, can someone suggest a way to get equivalent behaviour (the
ability to set "ethX" names based on MAC address) using the current
infrastructure? (Preferably as of RHEL 7, so systemd 219 plus a bunch of
patches.)

it was not removed - boot with "net.ifnames=0 biosdevname=0"

just use network.service on RHEL7 as all the time before and enter the
MAC in
the ifcfg-file as all the time before

On
https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
it says:

"For a longer time udev shipped support for assigning permanent "ethX"
names to certain interfaces based on their MAC addresses.  This turned
out to have a multitude of problems.....As a result support for this has
been removed from systemd/udev a while back."

If that is not accurate then maybe it should be updated

since when do you need udev for that?
you don't and you did not



[root@mail-gw:~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:50:56:bd:35:50

ONBOOT=yes
ARPCHECK=no
BOOTPROTO=static
TYPE=Ethernet
MODE=Managed
IPADDR=**.**.**.**
NM_CONTROLLED=no
IPV6INIT=no
NETMASK=255.255.255.0
GATEWAY=**.**.**.**

that said from somebody which switched the way below eth0 and eth1 on a CentOS7 mini-PC acting as router months ago
