Since the introduction of the ice driver the code has been double-shifting the RSS enabling field, because the define already has shifts in it and can't have the regular pattern of "a << shiftval & mask" applied.
Most places in the code got it right, but one line was still wrong. Fix this one location for easy backports to stable. An in-progress patch fixes the defines to "standard" and will be applied as part of the regular -next process sometime after this one.
