Do you know if changing the flag previously had any effect? I would suspect the bug was the fact that it was listing itself as being able to be toggled when the value of the flag was ignored. I would be interested in seeing an ethregs dump for the old version with the flag on and off in order to verify if the flag actually had any effect. > [root@compute05 src]# ethtool -K enp9s0f0 rx-vlan-filter off > > *Could not change any device features* > > > > Any idea how to overcome this issue? The in-kernel driver that is currently in net-next allows you to enable VLAN promiscuous mode on the PF by just setting the promiscuous flag. With that you could make it so the PF could receive all VLANs while the VFs were still being VLAN filtered. This feature should eventually be back-ported and will likely be available in some future version of the out-of-tree ixgbe driver. I can submit a patch that will allow the functionality to also be enabled via the ethtool flag and can have that submitted later today. - Alex ------------------------------------------------------------------------------ Transform Data into Opportunity.
