Hello Igor, Sorry for the delay. I'm a little hesitant to share our ixgbe patch to change this behavior because Jack has checked in changes to igb that make me think that our change is not correct. Or, at least, that he's probably working on fixing ixgbe the right way. Jack, are you planning to copy the reorganization of igb_setup_vlan_hw_support() over to ixgbe_setup_vlan_hw_support?
