[-- Attachment #1 --] Hi, Is there any high performance penalty to use ng_vlan and from here hook different vlans compared to use the vlan interface. To my knowledge the vlan interface is using the hardware filter on the card when it's available and the ng_vlan is not. But nowadawas with CPUs is the perforance too much impacted?
