> Add check of coalescing parameters received through ethtool are within

> Driver gets the coalescing rx/tx-usecs and rx/tx-frames as set by the
> users through ethtool. The ethtool support up to 32 bit value for each.
> However, mlx4 modify cq limits the coalescing time parameter and
> coalescing frames parameters to 16 bits.
> Return out of range error if user tries to set these parameters to
> higher values.
> Change type of sample-interval and adaptive_rx_coal parameters in mlx4
> driver to u32 as the ethtool holds them as u32 and these parameters are
> not limited due to mlx4 HW.
