Re: [RFC PATCH v3 1/6] qemu_monitor: Added QEMU's "request-ebpf" support.

Added code for monitor and monitor_json. The "request-ebpf" return's eBPF binary object encoded in base64. QEMU provides eBPF that can be loaded and passed to it from Libvirt. QEMU requires exact eBPF program/maps, so it can be retrieved using QAPI. To load eBPF program - administrative capabilities are required, so Libvirt may load it and pass it to the QEMU instance. For now, there is only "RSS"(Receive Side Scaling) for virtio-net eBPF program and maps.
