bonding: support encapsulated ipv6 TSO



If using a sixtofour device on top of a bonding device,
skb segmentation of TCP traffic is done right before calling
bonding xmit, because bonding only enables TSO for IPv4.

This patch improves single flow performance by about 120 % on my hosts,
because segmentation is deferred right before calling slave xmit.
