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
