Could not find TSO/LRO setting

[mastermindsos]

Hello.

I am looking for this setting.
In the wiki, it says that this setting could be found in System->Settings->Networking.
But I could not find "Networking" category.
I only found net.inet.tcp.tso under "Tuneable" category.
Is it the same thing? What is the correct value to disable it? 0?
What about LRO?

Thank you.
