receptionStartedSignal for LayeredEthernetInterface missing

[haug-den-lucas]

I have a scenario, with two TsnDevices (one sender and one receiver), where I need to keep track and perform actions based on the following four timestamps

To my understanding, in INET this corresponds to:

• t1: transmissionStartedSignal
• t2: transmissionEndedSignal
• t3: receptionStartedSignal
• t4: receptionEndedSignal

I think t1, t2 and t4 work just as they should and are emitted by the PacketTransmitter and PacketReceiver in the phyLayer of LayeredEthernetInterface.
However, it seems to me, that the receptionStartedSignal is not implemented here at all.
Also to me it does not seem like there is a simple one-line fix for this problem.

Would be great if this could be fixed, or if someone can guide me in the right direction so I can fix it myself.

Try using EthernetStreamingPhyLayer instead of EthernetPhyLayer. The default implementation doesn't provide that signal but the streaming variant should. Let me know if it works for you!
