They don't have a userspace driver either, they all have a kernelspace
hack on kernel 2.6.15 or so :/

- StorLink reference design SL93512R (and the rest of them, and later resol=
d
  from Cortina Systems). I got this from Imre Kaloz who got it from StorLin=
k.

- ITian Square One
  https://dflund.se/~triad/krad/itian-squareone/
  https://openwrt.org/toh/itian/square_one_sq201
  (The place where I started this switch support.)
  using the same hack as above.

HEY! You sent that to me :D

I think a bunch of other random router vendors copied this from the StorLin=
k
reference design as well, I just don't have all the Gemini devices.
