Thanks a lot, Michi.
Then how can I verify that IPV6 can be really running on our
NIC? Of course I have to build a kernel which can support IPV6 firstly, but how
to verify it’s really working? Use ping6?

Can anyone throw some light on this question?
You do not need to change the nic driver to support IPv6 unless it's the
driver is totally broken. Network cards and drivers operate on layer 2 and
generally do not care what you do on layer 3 and above. However in some cases
hardware accelerations like "TCP segmentation offloading" may be
available
which partly violates this layer separation. But this is "only" a
performance
issue.
