Use the same port for TCP and WebSocket

[NihiliumOnMarz]

I am trying to listen on /tcp/1111, /tcp/1111/ws, and /tcp/1111/tls/ws and getting error bind: Only one usage of each socket address (protocol/network address/port) is normally permitted."}

I thought LibP2P was capable of this?

This has to be implemented manually in each transport (see https://grep.app/search?q=quicreuse&filter[repo][0]=libp2p/go-libp2p).
AFAIK this is only implemented across quic* and webrtc transports now.

Looking through the code in TCP transport it has an option for reuse port but I do not see it in websocket transport. Is there an easy way to add?

Not easily, no. It's not just a matter of saying "reuse this port", you need to be able to detect that the connection is not for you and pass it off to the correct transport.

@NihiliumOnMarz is there a specific use case you need this for?

Related libp2p/specs#608 I'll submit a PoC.
