Realtek Ethernet interfaces usually still work without such firmware.
Some Linux (kernel) drivers, like those for Realtek Ethernet interfaces, try
to load non-free firmware. Trisquel uses scripts from Linux-libre to disable
non-free firmware loading in its Linux packages. So that message is just
Trisquel's Linux notifying you that the Realtek Ethernet driver would have
tried to load non-free firmware but didn't.
