That's a change in how now udevd assigns names to ethernet devices. Now your devices use the "Predictable Interface Names", which are based on (and quoting the sources):
- Names incorporating Firmware/BIOS provided index numbers for on-board devices (example: eno1)
- Names incorporating Firmware/BIOS provided PCI Express hotplug slot index numbers (example: ens1)
- Names incorporating physical/geographical location of the connector of the hardware (example: enp2s0)
- Names incorporating the interfaces's MAC address (example: enx78e7d1ea46da)
- Classic, unpredictable kernel-native ethX naming (example: eth0)
The why's this changed is documented in the systemd freedesktop.org page, along with the method to disable this:
ln -s /dev/null /etc/udev/rules.d/80-net-setup-link.rules
or if you use older versions:
ln -s /dev/null /etc/udev/rules.d/80-net-name-slot.rules

Following the freedesktop,org link, the main point is:The classic naming scheme for network interfaces applied by the kernel is to simply assign names beginning with "eth" to all interfaces as they are probed by the drivers. As the driver probing is generally not predictable for modern technology this means that as soon as multiple network interfaces are available the assignment of the names is generally not fixed anymore and it might very well happen that "eth0" on one boot ends up being "eth1" on the next. This can have serious security implications...

Since there is no...fNpart at the end of the NIC name, we can deduce that the function number is 0. After translating the numbers to hexadecimal (10 = "a" in hex), we know thatenp0s10means PCI device ID00:0a.0.
