> The code was intially moved from i40e_ethtool.c into i40e_ethtool_stats.h
> as a way of better logically organizing the code. This has two problems.
> First, we can't have an inline function with variadic arguments on all

> Patches which actually attempt to combine or share code between the i40e

> Rather than fixing the one function which causes build issues, just move
> this code back into the i40e_ethtool.c and i40evf_ethtool.c files. Note
> that we also change these functions back from static inlines to just
> statics, since they're no longer in a header file.

> generic so that it can be shared across drivers as part of ethtool

Applied and after the build checks out will be pushed to net-next.

Thanks.
