Gates:

pppg [ ]	inout		gates from overlay
ethg [ ]	inout		unused here

Unassigned submodule parameters:

Name	Type	Default value	Description
accessNet.channelTypes	string		list of (tx) channel types (from common/channels.ned)
accessNet.channelTypesRx	string		list of (rx) channel types (from common/channels.ned)
accessNet.useIPv6Addresses	bool	false
networkLayer.ip.procDelay	double	0s
networkLayer.arp.retryTimeout	double	1s	number seconds ARP waits between retries to resolve an IP address
networkLayer.arp.retryCount	int	3	number of times ARP will attempt to resolve an IP address
networkLayer.arp.cacheTimeout	double	120s	number seconds unused entries in the cache will time out
ppp.ppp.mtu	int	4470
eth.mac.promiscuous	bool	false	if true, all packets are received, otherwise only the ones with matching destination MAC address
eth.mac.address	string	"auto"	MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0.
eth.mac.txrate	double	100Mbps	maximum data rate supported by this station (bit/s); actually chosen speed may be lower due to auto- configuration. 0 means fully auto-configured.
eth.mac.duplexEnabled	bool	true	whether duplex mode can be enabled or not; whether MAC will actually use duplex mode depends on the result of the auto-configuration process (duplex is only possible with DTE-to-DTE connection).
eth.mac.mtu	int	1500
