This function tells the firmware what rates it can use.
Put the 3SS and 4SS HT rates supported by the other station into the
rate mask.
Remove the 3SS and 4SS rates from the rate mask if the hardware only has
2 spatial streams.
And finally, select the right rate ID (a parameter for the firmware)
when the hardware has 3 spatial streams.
