Enable this transport if you plan to run OpenWRT in a virtual machine and the hypervisor supports Virtual Sockets over virtio (Incus for example). Usually needed by "guest agents" to function, as it provides a communication channel between the guest os and the hypervisor. The module will be called vmw_vsock_virtio_transport. endef $(eval $(call KernelPackage,vsock-virtio))
