A Device for a Point to Point Network Link.
This PointToPointNetDevice class specializes the NetDevice abstract base class. Together with a PointToPointChannel (and a peer PointToPointNetDevice), the class models, with some level of abstraction, a generic point-to-point or serial link. Key parameters or objects that can be specified for this device include a queue, data rate, and interframe transmission gap (the propagation delay is set in the PointToPointChannel).
ns3::PointToPointNetDevice is accessible through the following paths with Config::Set and Config::Connect:

Make and return a MAC multicast address using the provided multicast group.
RFC 1112 says that an Ipv4 host group address is mapped to an Ethernet multicast address by placing the low-order 23-bits of the IP address into the low-order 23 bits of the Ethernet multicast address 01-00-5E-00-00-00 (hex). Similar RFCs exist for Ipv6 and Eui64 mappings. This method performs the multicast address creation function appropriate to the underlying MAC address of the device. This MAC address is encapsulated in an abstract Address to avoid dependencies on the exact MAC address format.
In the case of net devices that do not support multicast, clients are expected to test NetDevice::IsMulticast and avoid attempting to map multicast packets. Subclasses of NetDevice that do support multicasting are expected to override this method and provide an implementation appropriate to the particular device.

The trace source fired for packets successfully received by the device immediately before being forwarded up to higher layers (at the L2/L3 transition).
This is a promiscuous trace (which doesn't mean a lot here in the point-to-point device).

This corresponds to the maximum number of bytes that can be transmitted as seen from higher layers. This corresponds to the 1500 byte MTU size often seen on IP over Ethernet.

A trace source that emulates a promiscuous mode protocol sniffer connected to the device.
This trace source fire on packets destined for any host just like your average everyday packet sniffer.
On the transmit size, this trace hook will fire after a packet is dequeued from the device queue for transmission. In Linux, for example, this would correspond to the point just before a device hard_start_xmit
where dev_queue_xmit_nit
is called to dispatch the packet to the PF_PACKET ETH_P_ALL handlers.
On the receive side, this trace hook will fire when a packet is received, just before the receive callback is executed. In Linux, for example, this would correspond to the point at which the packet is dispatched to packet sniffers in netif_receive_skb
.
