[LARTC] how to classify non-IP packet

[Liu Zhiyong <liuzhiyo@xxxxxxxxxxxxxxx>]

I implemented a protocol QRoute(same level as IP). Now I can classify the
Qroute packet and IP packet according to the "protocol" field, but when I
tried to further classify QRoute packet according to the first 2 bytes of
the packet( match u32 0x00 0xff at 0) , it failed. anyone can help me?
