How do I specify Network Adapter to be vmxnet3 in Fusion?

Hi,

I am runnning a Cent-OS VM in Fusion that won't boot if a vNIC is anything other than vmxnet3.

When I add an adapter through Fusion UI it creates an e1000 type and I can't find a way to modify this.

Guessing I probably need to edit .vmx directly, but I'd like to know exactly what I need to add.

Thanks.
