Overview

QEMU ‘socket` netdev backend – a thin wrapper, not an abstraction.

Whatever the user puts in ‘socket_opts` is emitted verbatim as the netdev options, so the mode is entirely the user’s choice:

socket_opts: "mcast=230.0.0.1:1234"   -> multicast, N-way (Linux/Windows)
socket_opts: "listen=:1234"           -> point-to-point, this VM listens
socket_opts: "connect=127.0.0.1:1234" -> point-to-point, this VM connects

For listen/connect the user decides which VM listens and which connects; the plugin does not assign roles. (listen/connect is the no-root, macOS-friendly path; mcast does not work on macOS.)

When ‘socket_opts` is unset it falls back to multicast using `mcast_addr` (default 230.0.0.1:1234) for backward compatibility.
