This series adds a selftest that pings over 802.1q, 802.1ad and
QinQ VLAN interfaces with RX VLAN stripping offloads enabled
and disabled.

This series contains only the selftest part of [1].

Changes since v4 of [1]:
- dropped the cfg.require_ipver("4") call
- used a relative import for the lib
- the "hw" variants no longer require rx-vlan-stag-hw-parse to
be changeable. They now enable the features the device supports,
so QinQ traffic is also tested with only C-Tag stripping enabled
(reported by Sashiko)

Thanks for posting.
Nicolai's suggestion make sense, please make sure you fetch net-next
and rebase because the gro test has changed.
