Helper program. Loads eBPF RSS program and maps and passes them through unix
socket.
Libvirt may launch this helper and pass eBPF fds to qemu virtio-net.
Also, libbpf dependency for now is exclusively for Linux.
Libbpf is used for eBPF RSS steering, which is supported only by Linux TAP.

Well, the current code would require additional capabilities with
"kernel.unprivileged_bpf_disabled=1", which may be possible on RedHat

Hi,
I wonder if this can be done as helper for TAP/bridge.
Well, it does already, libvirt may create TAP device and pass it in
command line or using getfd qmp command.
E.g it's the qemu to launch those helper with set-uid.
Then
