Function maxInFlightConnectionAttemptsPerClient

wgengine/netstack/netstack.go:110–120

maxInFlightConnectionAttemptsPerClient is the same as maxInFlightConnectionAttempts, but applies on a per-client basis (i.e. keyed by the remote Tailscale IP).

// maxInFlightConnectionAttempts, but applies on a per-client basis

	// For now, allow each individual client at most 2/3rds of the global
	// limit. On all platforms except mobile, this won't be a visible
	// change for users since this limit was added at the same time as we
	// bumped the global limit, above.
