/**

 *
 * \brief API to create IPv6 RAW socket instances
 *
 * This abstract class defines the API for IPv6 RAW socket factory.
 *
 * A RAW Socket typically is used to access specific IP layers not usually
 * available through L4 sockets, e.g., ICMP. The implementer should take
 * particular care to define the Ipv6RawSocketImpl Attributes, and in
 * particular the Protocol attribute.
 * Not setting it will result in a zero protocol at IP level (corresponding
 * to the HopByHop IPv6 Extension header, i.e., Ipv6ExtensionHopByHopHeader)
 * when sending data through the socket, which is probably not the intended
 * behavior.
 *
 * A correct example is (from src/applications/model/radvd.cc):
 * \code
   if (!m_socket)
     {
       TypeId tid = TypeId::LookupByName ("ns3::Ipv6RawSocketFactory");
       m_socket = Socket::CreateSocket (GetNode (), tid);
 
       NS_ASSERT (m_socket);
 
       m_socket->SetAttribute ("Protocol", UintegerValue(Ipv6Header::IPV6_ICMPV6));
       m_socket->SetRecvCallback (MakeCallback (&Radvd::HandleRead, this));
     }
 * \endcode
