Even if the RAVENNA ASIO driver can run on any Gigabit Ethernet Adapter, including the onboard one, it is recommended to use a dedicated card.
Separate Network card is recommended for better RAVENNA ASIO performances.
Merging recommends Intel Gigabit network adapters.
For better performances, such dedicated network card can be configured, in Windows Control Panel > Network and sharing center.
Select Change Adapter settings, then right click on the card and select Properties.
