Hello Jiayu,
I wonder why librte_gso only supports TCP GSO above IPv4.
Can you please explain why TCP GSO is not supported above IPv6?
Are there plans to support it?
Regards,
Ophir

Hi Ophir,
Comparing with IPv6, IPv4 is used more widely used and more popular.
Therefore, when proposed the GSO library, we just planned to support
IPv4.
Do you have any usage scenarios that depend on IPv6?
Thanks,
Jiayu

The same usage scenarios with IPv4 may be applicable to IPv6 since the
application requesting TSO at layer 4 may not care about which IP is used at layer 3.

OK. We have plan to support IPv6, but which release is not decided.
