When the VF is in a port VLAN, this is the incorrect behavior because it will allow the VF to receive traffic outside of its port VLAN domain. Fortunately this only resulted in the VF(s) receiving broadcast traffic outside of the VLAN domain because all of the VLAN promiscuous rules are based on the port VLAN ID. Fix this by setting the .disable_rx_filtering VLAN op to a no-op when a port VLAN is enabled on the VF. Also, make sure to make this fix for both Single VLAN Mode and Double VLAN Mode enabled devices.
