vSphere license required for Cisco VIC 1225

Hello,

Does anyone knows the vSphere license requirements to use a Cisco UCS VIC 1225 PCI card? This one creates up to 256 virtual PCI devices to separate traffic inside the physical interface.

We are in the design part of the proyect and we are considering Standard licenses since it's a small deployment, I want to make sure this card does not require Enterprise Plus vSphere license cause maybe this card would need a distribuited switch

Thanks
