Firmware bug was suspect by Intel. However, a software fix was later discovered, and provided by Intel. This patch will be upstreamed in 1705?

DPDK patch fixed the problem.

concern is that i40e during initialization allows untagged packets on RX, also VFs without VLAN filter added able to receive VLAN with any tag ( for example driver bound to VF which is not in the config.json file will be able to receive packets with ANY VLAN ID)
workaround: to set rx_vlan_filter to VLAN 0 when VF queue is enabled but no config for the VF exists
and set "don't allow untagged"
