Hash IPv4 TCP/UDP flows across N independent data VSOCK connections to reduce head-of-line blocking. Stream 0 on -vsock-port is always the control stream; -vsock-streams N adds N data streams on ports +1..+N (default 0 for backward-compatible single-stream behavior).

Caveat: I haven't tested this yet to see if it yields improved performance. This was the result of some back and forth analysis with AI. |

Interesting idea. This is worth exploring but I'd like to see latency and throughput numbers. The changes are fairly complex, so I hope there's more than just a marginal improvement. |

Note: Reading off the tun interface is still serialized. A future improvement could read off the tun interface and delegate vsock writes to parallel writers.
