CONFIG_IP_NF_TARGET_LOG
TCPLAG target support
CONFIG_IP_NF_TARGET_TCPLAG
  This option adds a `TCPLAG' target, intended for INPUT, OUTPUT and
  FORWARD chains.

  This target has no effect on packets but will passively monitor TCP/IP
  connections and send lag estimates to syslog. Lag estimates are
  generated by considering the time delay between SEQ and matching ACK,
  which does not map precisely to any particular network property.
  We can say that a fast network will typically give smaller lag values
  than a slow network.

  Safest option is to choose `M' here and compile as a module,
  the module will do nothing until activated using the `iptables' utility.
