By default, it will be called em1 or pci<slot>#<port>.  There is no
way to know "there is only one NIC" at any point in time, as each
device is discovered in parallel, and devices may be hot-added or
hot-removed at any time.

To force any one port to be named eth0, you would create an entry for
the device in /etc/udev/rules.d/70-persistent-net.rules just as is
done today.
