> Subject: [PATCH net-next v3] drivers, ixgbe: export vf statistics
>=20
> This change retrieves network metrics for virtual functions from the devi=
ce
> and exports them via the iproute2 interface.
>=20
> 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 di=
ff
> between this version and the previous version 2.0.72.4 was used to identi=
fy
> required changes. The export via ethtool is omitted in favor of using the
> standard ndo_get_vf_stats interface.
>=20
> Per-VF statistics can now be printed, for instance, via
>=20
>   ip --statistics link show dev eth0
>=20
> Signed-off-by: Maximilian Heyne <mheyne@amazon.de>
> ---
> v2: implemented the ndo_get_vf_stats callback
> v3: as per discussion, removed the ethtool changes
