Except Loki has a matriarchal surname for some reason that I never actually learned. So the names got switched.
But as far as the comics--which are what the movie is adapting, not the myths--go, Laufey has always been Loki's father and Farbauti has always been his mother, so it's a gender-swap once removed. Stan Lee, Jack Kirby, and possibly Larry Leiber (Stan's younger brother who scripted a lot of early Thor appearances) are the ones who got it wrong all those decades ago.
Those funky shapeshifting Frost Giants.
I don't know how many books back then were actually in print of the Norse myths, so, in the creators defense it could be one of those things where they used books that were wrong or different too.
Heck even my versions of the translated myths have very little on Loki's parents, like there's very little background on Sif.
