writting NIC driver for IPV6

[Gang Lei (雷刚)]

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?

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.
