It's a bit confusing, because there are product numbers associated
with NICs, and with different individual component chipsets, and some
code is shared.  Pyun YongHyeon, who has been working on the re(4) and
rl(4) drivers in -CURRENT and -STABLE recently, could probably tell
you more (I've cc'ed him).
