ESXi 5.5 Compatibility Issue

I get the following error while installing (for the first time) ESXi 5.5: "No network adapter is detected".

My NIC is Realtek 8111GR Gigabit LAN. I ran a search for this term in VMware Compatibility Guide: System Search but got no result.

Does this mean that the NIC I am using isn't supported? If so, what can be done?

Thanks
