##sniff([count=0,] [prn=None,] [store=1,] [offline=None,] [lfilter=None,] + 
##      L2ListenSocket args) -> list of packets
##
##  count: number of packets to capture. 0 means infinity
##  store: wether to store sniffed packets or discard them
##    prn: function to apply to each packet. If something is returned,
##         it is displayed. Ex:
##         ex: prn = lambda x: x.summary()
##lfilter: python function applied to each packet to determine
##         if further action may be done
##         ex: lfilter = lambda x: x.haslayer(Padding)
##offline: pcap file to read packets from, instead of sniffing them
##timeout: stop sniffing after a given time (default: None)
##L2socket: use the provided L2socket
##opened_socket: provide an object ready to use .recv() on
##stop_filter: python function applied to each packet to determine
##             if we have to stop the capture after this packet
##             ex: stop_filter = lambda x: x.haslayer(TCP)
