The NanoPi R4S has a RTL8169 controller with MSI-X capabilities. Post irqbalance setup I verified it's properly distributing IRQs. I'm using mine as a transparent bridge and network monitor. https://news.ycombinator.com/item?id=27236081

        Capabilities: [b0] MSI-X: Enable+ Count=4 Masked-

Interesting, I'll have to check that device out. I'm using Raspberry Pi 4b and it does not have the right capabilities, ethtool just says the operation is not supported:

    sudo ethtool -x eth0
    Cannot get RX ring count: Operation not supported

I might have to add a NanoPi to my collection
