The ath5k gives exactly the same results as original Atheros HAL:

  #define INIT_CLOCKMHZSCALED     0x64000000
  unsigned long clockMhzScaled =3D INIT_CLOCKMHZSCALED;
  if (IS_CHAN_TURBO(chan)) clockMhzScaled *=3D 2;
  coef_scaled =3D clockMhzScaled / chan->channel;

I don't know how the calculations work, they might be explained in the=20
referenced patent, but I didn't change their semantics at all.

Where's the patch?
