Tunneling packet is encapsulated format, in order to extend another tunneling type support and distinguish between tunneling and non-tunneling packet,
we had better provide independent common filter API. 
The existing generic filter function is related to normal L2 packet filter(non-tunneling packet). If there are two kind of filter APIs, one is for normal L2 packet, 
other is for tunneling packet, which will make user more clear when and how to use them.
