Control information for sending/receiving packets over IPv6.
To send a packet over IPv6, fill in an IPv6ControlInfo object, attach it to the packet with the C++ method setControlInfo(), the send it to the IPv6 module.
When IPv6 delivers packets to higher layers, it also attaches similar IPv6ControlInfo objects to them.
When sending, the following fields are required:
Optional fields:
