Name	Type	Description
EthernetSignalBase	packet	Abstract base class for various Ethernet traffic types: EtherJam, EtherFilledIfg and EtherPhyFrame.
EthernetSignal	packet	Represents dataframe on the Ethernet.
EthernetJamSignal	packet	Represents jam on the Ethernet.
EthernetFilledIfgSignal	packet	Represents a filled inter-frame gap in burst mode. Also used for calculating IFG times.
