Update - after setting the MAC in ifcfg-enp5s1 to what is shown in ifconfig -a, I have success:

I whacked up a quick file

[root@localhost network-scripts]# cat ifcfg-eth1

HWADDR=DB:03:03:06:63:20

and attempted an ifup eth1

[root@localhost network-scripts]# ifup eth1
Error: no device found for connection 'System eth1'.

OH, NOW THIS IS INTERESTING  (pardon the shout):

[root@localhost network-scripts]# dmesg | grep -e eth

soooooo

[root@localhost network-scripts]# vi ifcfg-enp5s1
[root@localhost network-scripts]# ifdown enp5s1

Hmmm..... is anything in 'ls -l /sys/class/net ' that softlinks to

I'm thinking you'll see an entry for lo and enp2s0, but not the missing
NIC (unless we get lucky). Anyway - wherever the enp2s0 goes, follow
that to see what else is in that directory - probably something like
/sys/devices/pci0000\:00/0000\:00\:01.0/

For example, my two NICs

$ lspci  | grep Ethernet
01:00.0 Ethernet controller: Intel Corporation 82580 Gigabit Network
Connection (rev 01)
01:00.1 Ethernet controller: Intel Corporation 82580 Gigabit Network
Connection (rev 01)

are in /sys/devices/pci0000\:00/0000\:00\:01.0/0000:01:00.0 and
0000:01:00.1 so you hopefully have entries akin to 0000:02:00.0 and
  0000:05:00.0 - anything in there, specifically in (hopefully a) net
directory?

Also, anything from dmesg | grep -e eth ?

Trying to find out if maybe we just need to get the eth number of the
card and do ifconfig ethNUMBER up before network-manager starts.
