> This change retrieves network metrics for virtual functions from the device

> The code for retrieving the statistics from the device is taken from the out-of-
> tree driver.  The feature was introduced with version 2.0.75.7, so the diff
> between this version and the previous version 2.0.72.4 was used to identify
> required changes. The export via ethtool is omitted in favor of using the
> standard ndo_get_vf_stats interface.

> Per-VF statistics can now be printed, for instance, via
> 
>   ip --statistics link show dev eth0

> v2: implemented the ndo_get_vf_stats callback
> v3: as per discussion, removed the ethtool changes
