I just saw your v6. So, what does this mean? If the device is capable of doing this, but there is no way to enable/disable it, it would mean that it will be enabled or disabled by default, right?

I see that X550 NIC is the only one capable of this. Maybe Wenzhuo can help on clarifying this.

I would say that, if it is enabled when it is capable, then you should print "on", But printing only "RX Outer IPv4 checksum" does not give any information (when all the rest of the capabilities show on/off).

Qiming: Ok, I'll check with Wenzhuo, Thank you for your advice for the unsuitable print in this place .

Thanks,
Pablo
