Ben,

you're on to something:


# ethtool -i eth0
driver: vif
version:
firmware-version:
expansion-rom-version:
bus-info: vif-0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no



Indeed, this only happens in XEN guests running on a jessie host (didn't
get around yet to test whether a stretch host makes the difference).

On any other hw I own (a couple of e1000e and a r8169), ethtool always
exits 0, with changes to offloading having been made or not.

Sorry for not mentioning the fact about VMs earlier...just didn't think
of it.


Cheers
Daniel
