Precisely why I shouted! Reboot in progress...
Yes, the NICs come up as expected after boot.

....do they NICs it come up as expected through a reboot?

Previous
mung I moved the Intel NIC to a different PCI slot and it
subsequently
did not appear as an Ethernet device in lspci. So I replaced it
with a
RealTek NIC (MAC DB0303066320) in the slot that failed and now I
have
entries:

I whacked up a quick file

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

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

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.
