Add menuconfig options to include modules for (virtio) vsockets. These are used when running as Guest OS in a VM. OpenWRT can be run in a vm (mostly commonly on the x86/64 and armsr targets). Often it is convenient to have some sort of guest agent running, to ease communication from host to guest. Virtual Sockets provide this communication channel. Virtio is a transport for this communication channel. Virtual Sockets over virtio are for example used by Incus. Virtual Sockets in general are used by most hypervisors, including VMware, Hyper-V, and libvirt (qemu). These may need other transport-specific modules not included in this commit.

Support hosting fully virtualized guest machines using hardware

virtualization extensions. You will need a fairly recent

processor equipped with virtualization extensions. You will also

need to select one or more of the processor modules.
|

This module provides access to the hardware capabilities through

a character device node named /dev/kvm.

Kernel support for Virtual Sockets over virtio.
|

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.
