Thanks David.

Yes, infact we have a card which supports TSO over IPv6.
This support in the kernel will be helpful to us.

No, the support is not there, not because of any technical reason
but simply because no devices exist which can handle ipv6 TCP
TSO.

If you have a card which can do it, we simply need to add a new
NETIF_F_TSO_IPV6 flag and the necessary tcp*.c code.
