Hello,

I have study the BPF, and I know it calls Socket Filtering in Linux.
    (user)
        |
    (buffer)
        |
    (BPF)    (origin protocol stack)
        |           |
    (Data Link Layer)

Does the buffer above BPF is skb_buff?
If yes, origin protocol stack will get packet from it.
After the packet be processed, the packet in the buffer will be del.
Right? Thanks for your advise.
