> Due to the resolution of the register controlling interrupt rate limiting, setting
> certain values for the interrupt rate limit make it appear as though the
> limiting is not completely accurate.  The problem is that the interrupt rate
> limit is getting rounded down to the nearest multiple of 4.  This patch fixes
> the problem by adding some feedback to the user as to the actual interrupt
> rate limit being used when it differs from the requested limit.  Without this
> patch setting interrupt rate limits may appear to behave inaccurately.
