[PATCH 2/5] virtio-net: Added property to load eBPF RSS with fds.

Changed eBPF map updates through mmaped array. Mmaped arrays provide direct access to map data. It should omit using bpf_map_update_elem() call, which may require capabilities that are not present. Also, eBPF RSS context may be initialized by file descriptors. virtio-net may provide fds passed by
