It's not the wrong module.  If it didn't support your hardware then it
wouldn't do anything at all.

When Realtek started making chips in the RTL81xx family that attached
to the PCI Express (rather than classic PCI) bus they branched the
driver, with r8169 supporting the old chips and r8168 the new.  But
the drivers have a lot of common code.  In mainline Linux, support for
the new chips was added to r8169 instead.

All that said, r8168 probably has some fixes that mainline r8169 does
not (yet).
