Unassigned submodule parameters

Name	Type	Default value	Description
pcapRecorder.displayStringTextFormat	string	"rec: %n pks"	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
pcapRecorder.verbose	bool	true	Whether to log packets on the module output
pcapRecorder.recordEmptyPackets	bool	true	Specifies if zero length packets are recorded or not
pcapRecorder.enableConvertingPackets	bool	true	Specifies if converting packets to link type is allowed or not
pcapRecorder.pcapFile	string	""	The PCAP file to be written, suggested value: pcapFile = "${resultdir}/${configname}-#${runnumber}" + fullpath() + ".pcap"

pcapRecorder.snaplen	int	65535	Maximum number of bytes to record per packet
pcapRecorder.timePrecision	int	6	Time precision in recorded file. pcap supports only 6 (usec) or 9 (nanosec), pcapng supports more values (see 'if_tsresol' option in pcapng file format).
pcapRecorder.dumpBadFrames	bool	true	Enable dump of frames with hasBitError
pcapRecorder.sendingSignalNames	string	"transmissionEnded"	Space-separated list of outbound packet signals to subscribe to
pcapRecorder.receivingSignalNames	string	"receptionEnded"	Space-separated list of inbound packet signals to subscribe to
pcapRecorder.dumpProtocols	string	"ethernetmac ppp ieee80211mac"	Space-separated list of protocol names as defined in the Protocol class
pcapRecorder.packetFilter	object	"*"	Which packets are considered, matches all packets by default
pcapRecorder.helpers	string	""	Usable PcapRecorder::IHelper helpers for accept packettype and store/convert packet as specified linktype currently available: "inet::AckingMacToEthernetPcapRecorderHelper"
pcapRecorder.alwaysFlush	bool	false	Flush the pcapFile after each write to ensure that all packets are captured in case of a crash
