Any chance we could see support for QNAP QNA-UC5G1T USB 3.0 to 5GbE adapter? It's a reliable and cheap 5Gbe USB adapter that can be used in servers without PCIe.   It uses the Aquantia drivers which Unraid already has some support apparently, I guess just not for this model which is Aquantia AQtion AQC111U driver.   Product url: https://www.qnap.com/en/product/qna-uc5g1t
