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