+// Package udpmux provides a custom implementation of a UDP multiplexer
+// that allows multiple logical ICE connections to share a single underlying
+// UDP socket. This is based on Pion's ICE library, with modifications for
+// NetBird's requirements.
+//
+// # Background
+//
+// In WebRTC and NAT traversal scenarios, ICE (Interactive Connectivity
+// Establishment) is responsible for discovering candidate network paths
+// and maintaining connectivity between peers. Each ICE connection
+// normally requires a dedicated UDP socket. However, using one socket
+// per candidate can be inefficient and difficult to manage.
+//
+// This package introduces SingleSocketUDPMux, which allows multiple ICE
+// candidate connections (muxed connections) to share a single UDP socket.
+// It handles demultiplexing of packets based on ICE ufrag values, STUN
+// attributes, and candidate IDs.
+//
+// # Usage
+//
+// The typical flow is:
+//
+//  1. Create a UDP socket (net.PacketConn).
+//  2. Construct Params with the socket and optional logger/net stack.
+//  3. Call NewSingleSocketUDPMux(params).
+//  4. For each ICE candidate ufrag, call GetConn(ufrag, addr, candidateID)
+//     to obtain a logical PacketConn.
+//  5. Use the returned PacketConn just like a normal UDP connection.
+//
+// # STUN Message Routing Logic
+//
+//		When a STUN packet arrives, the mux decides which connection should
+//		receive it using this routing logic:
+//
+//		Primary Routing: Candidate Pair ID
+//		  - Extract the candidate pair ID from the STUN message using
+//		    ice.CandidatePairIDFromSTUN(msg)
+//	   - The target candidate is the locally generated candidate that
+//	     corresponds to the connection that should handle this STUN message
+//		  - If found, use the target candidate ID to lookup the specific
+//		    connection in candidateConnMap
+//		  - Route the message directly to that connection
+//
+//		Fallback Routing: Broadcasting
+//		  When candidate pair ID is not available or lookup fails:
+//		  - Collect connections from addressMap based on source address
+//		  - Find connection using username attribute (ufrag) from STUN message
+//		  - Remove duplicate connections from the list
+//		  - Send the STUN message to all collected connections
+//
+// # Peer Reflexive Candidate Discovery
+//
+//	When a remote peer sends a STUN message from an unknown source address
+//	(from a candidate that has not been exchanged via signal), the ICE
+//	library will:
+//	  - Generate a new peer reflexive candidate for this source address
+//	  - Extract or assign a candidate ID based on the STUN message attributes
+//	  - Create a mapping between the new peer reflexive candidate ID and
+//	    the appropriate local connection
+//
+//	This discovery mechanism ensures that STUN messages from newly discovered
+//	peer reflexive candidates can be properly routed to the correct local
+//	connection without requiring fallback broadcasting.
