> routine
> 
> This is part 1 of the rx refactor series, just including changes to i40e.
> 
> This refactor aligns the receive routine with the one in ixgbe which was highly
> optimized.  This reduces the code we have to maintain and allows for
> (hopefully) more readable and maintainable RX hot path.
> 
> In order to do this:
> - consolidate the receive path into a single function that doesn't
>   use packet split but *does* use pages for rx buffers.
> - remove the old _1buf routine
> - consolidate several routines into helper functions
> - remove ethtool control over packet split

Changes present in debugfs dump stats, ethtool no longer shows packet split options
