Thanks for the report Lennart, I understand your frustration, as this
should probably work without user configuration.

However, please give this command a try:
ethtool --set-priv-flags ethX disable-source-pruning on

Hmm, our 4.9 kernel is just a touch too old to support that.  And yes
that really should not require a flag to be set, given the card has no
reason to ever do that pruning.  There is no justification you could
have for doing it in the first place.
