I assume that one use cases is where a VM (windows or Linux inside) does a eBPF (XDP) load into a virtual network interface, and the hypervisor manages to push that down to some engine in a physical card. In that case, we might have mixes of Windows, Linux and network card implementations of eBPF on the same "transaction" path. -- Michael Richardson , Sandelman Software Works -= IPv6 IoT consulting =- *I*LIKE*TRAINS*
