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?

HI all:
Thanks for your help in advance. Could anyone tell me how to revise NIC driver to support IPV6? Or it doesn??t need driver??s change to support IPV6? 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. -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
