    Do you need to call:
    Code:
    setsockopt(handle->fd, SOL_SOCKET, SO_ATTACH_FILTER, 
    			       &fcode, sizeof(fcode))
    Search: pf_packet packet filter

    With SO_ATTACH_FILTER you will have to specify the filter code but i want to block all IP packets and send only the packets, which may be useful.

    (Definition of useful may be dependent on data and not on any header information)
