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)
