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
