Shim performing 6LoWPAN compression, decompression and fragmentation.
This class implements the shim between IPv6 and a generic NetDevice, performing packet compression, decompression and fragmentation in a transparent way. To this end, the class pretend to be a normal NetDevice, masquerading some functions of the underlying NetDevice.
ns3::SixLowPanNetDevice is accessible through the following paths with Config::Set and Config::Connect:
Size of this type is 296 bytes (on a 64-bit architecture).

Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.
Reimplemented from ns3::Object.

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.
