As someone else had stated, it's not related to SystemD but
Fedora/RHEL has changed the way they handle some things.  NICs, for
instance, are no longer named after the device number (eth0, eth1,
eth2, etc.) but after the *driver* name.  Yes, it's a change but it
also makes sense.  IIRC this is how FreeBSD handles NIC names.

It's true that FreeBSD names their network interfaces after the driver.

But the consistent device naming in Linux comes from slot index
numbers, physical location and even the MAC (if so configured), and
not what driver it uses.

Okay that makes sense.

eno1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 0c:c4:7a:c8:a5:4c  txqueuelen 1000  (Ethernet)
eno2: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 0c:c4:7a:c8:a5:4d  txqueuelen 1000  (Ethernet)

Those two are my onboard nic, Intel - Scheme 1

enp10s0f0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 00:1b:21:94:72:37  txqueuelen 1000  (Ethernet)
enp10s0f1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 00:1b:21:94:72:36  txqueuelen 1000  (Ethernet)
enp9s0f0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 00:1b:21:94:72:35  txqueuelen 1000  (Ethernet)
enp9s0f1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500

Those four are on a PCI-E card, Intel - Scheme 3

05:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network

06:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network

09:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet

0a:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet

0a:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet

Anyway thanks for that link.

er, I meant to add that the 09: seems to correspond with the enp9s* and the 0a: seems to correspond with the enp10s*
