 """ Setups a packet filter bound with this NIO. Filter "freq_drop" has 1 argument "<frequency>". It will drop everything with a -1 frequency, drop every Nth packet with a positive frequency, or drop nothing. Filter "capture" has 2 arguments "<link_type_name> <output_file>". It will capture packets to the target output file. The link type name is a case-insensitive DLT_ name from the PCAP library constants with the DLT_ part removed.See http://www.tcpdump.org/linktypes.html for a list of all available DLT values. :param direction: "in", "out" or "both" :param options: options for the packet filter (string) """
