That's right, the pi3 doesn't have an eeprom to hold the tftp ip address. An alternative way to network-boot is to use Plan 9 as a boot loader: a (minimal) Plan 9 kernel can be loaded from the SD card, which will fetch the full Plan 9 kernel via tftp and copy it to /dev/reboot. That works even for older pi models (pi1 and pi2), but does require an SD card.
