Due to the wonders of the USB standards, with a USB4 host you're likely to get more consistent results using a thunderbolt adapter, rather than a USB based one. USB3.2 Gen 2x2 can do 20gbps and is what you'd need to support RTL8159 at full speed (as well as an OpenBSD driver supporting that chipset, I did start looking but nothing to show yet). A USB4 host is not mandated to support 2x2 (and even if they do it's possible only one port on the device does it). I have several aq(4) based devices and would suggest those if you want the best performance: - Sonnet Solo10G -- massive and heavy, because it's mostly a heatsink but works well; - QNAP QNA-T310G1T -- not recommended as it has a loud fan (note the SFP+ version does not have a fan) But if this isn't for a laptop the other suggestions people have given for devices with onboard 10Gbe are likely better and will cost less and have fewer headaches.
