For RAW sockets, an application can use any procotol for IPv4.  In IPv6, I
imagine there are problems if a RAW application opens a socket and uses a
known IPv6 extension header number as the protocol since now the IP layer
will expect that next header field to be an extension header.  Therefore,
is it a restriction now that an IPv6 RAW application cannot use an known
IPv6 extension header as the protocol on the socket call?

Thanks
