BTW, does your card handle ECN correctly? If not then we should change
the new ECN bit to apply to both TCPv4 and TCPv6 since

1) We now have a piece of hardware that handles TSO6 and it doesn't do ECN.
2) It's quite likely that if the NIC can handle ECN in TCPv4 then it can do
   it in TCPv6.

Don't we have a bigger problem if it doesn't support ECN with ipv6 TSO?
We either have to disable ECN when TSO is enabled like we used to for
ipv4, or provide the gso tcp segmentation for ipv6.  Right?
