Yeah, the BlueOnyx GUI chokes on the crazy network device names that the
new UDEV changes assign to network interfaces. We want (and support)
straightforward network interface names such as "eth0", "eth1" and so on.

To this end the initial setup of BlueOnyx made use of this script:

/usr/sausalito/sbin/write_udev.pl

It was used by /root/network_settings.sh in this way:

# Create/Update /etc/udev/rules.d/70-persistent-net.rules:
if [ ! -f /etc/udev/rules.d/70-persistent-net.rules ]; then
	/usr/sausalito/sbin/write_udev.pl >
/etc/udev/rules.d/70-persistent-net.rules
	# Let's get rid of ifcfg-* files for non-ethX interfaces:
	/bin/cp /etc/sysconfig/network-scripts/ifcfg-* /tmp/
	/bin/rm -f /etc/sysconfig/network-scripts/ifcfg-*
	/bin/cp /tmp/ifcfg-lo /etc/sysconfig/network-scripts/
fi

The script renames the obscured network devices to ethX (and so on) and
stores that info in /etc/udev/rules.d/70-persistent-net.rules

Which restores the traditional behaviour. Please run
/usr/sausalito/sbin/write_udev.pl and see if it dumps info for all your
network interfaces. If it does, you might want to redirect that info to
your 70-persistent-net.rules:

/usr/sausalito/sbin/write_udev.pl >
/etc/udev/rules.d/70-persistent-net.rules

Then (after a reboot) the interfaces should all be renamed to the
traditional forms and can be configured through the GUI.

Short of that: You can always manually create config files for the extra
NICs under /etc/sysconfig/network-scripts/

For example: If you want to configure your "enp2s0f1" interface, create
a /etc/sysconfig/network-scripts/ifcfg-enp2s0f1 and put the network
settings into it. Use /etc/sysconfig/network-scripts/ifcfg-eth0 as an
example.
