It took some time, but now we wanted to try your vlan offload settings - but
failed. Here is the current setting:

# ethtool -k p7p1 | grep vlan
rx-vlan-offload: on
tx-vlan-offload: on
rx-vlan-filter: on [fixed]
vlan-challenged: off [fixed]
tx-vlan-stag-hw-insert: off [fixed]
rx-vlan-stag-hw-parse: off [fixed]
rx-vlan-stag-filter: off [fixed]

And now:

# ethtool -K p7p1 rx-vlan-filter off
Could not change any device features
# ethtool --version
ethtool version 3.10
# uname -r
3.10.9



Wrong syntax? Any hints?
