The Realtek 81xx-family chips all have firmware in non-volatile memory,
but Realtek provides firmware updates to fix bugs.  In some cases those
bugs are quite serious, for example it can't establish a link with some
switches.  The driver tries to load a firmware update for the chip if it
has been issued, but will continue without if the file is missing.  But
there's no way for the installer to know generically that certain
firmware is optional, and I don't think it should be completely quiet
when the chip will otherwise be running known buggy firmware.
