please take a look at RFC2292. IPv6 raw socket will not send you
the IPv6 header nor extension header, it only sends up the real
payload. you will be able to grab information about IPv6 header and
extension header, via ancillary data stream.
so, userland appliation (like your ping6) do not need to worry about
extension header, normally. if you would like to take a look at,
you can always look at it via ancillary data stream.
I believe there are IPv6-ready Linux ping6 packages, you may want to
take a look at those.
