    NFC: LLCP raw socket support · 4463523b
    Thierry Escande authored
    This adds support for socket of type SOCK_RAW to LLCP.
    sk_buff are copied and sent to raw sockets with a 2 bytes extra header:
    The first byte header contains the nfc adapter index.
    The second one contains flags:
    - 0x01 - Direction (0=RX, 1=TX)
    - 0x02-0x80 - Reserved
    A raw socket has to be explicitly bound to a nfc adapter. This is achieved
    by specifying the adapter index to be bound to in the dev_idx field of the
    sockaddr_nfc_llcp struct passed to bind().
