### Description

file ipfs_impl.go of go-bitswap@0.7.0
```
func (bsnet *impl) Start(r Receiver) {
bsnet.receiver = r
bsnet.connectEvtMgr = newConnectEventManager(r)
for _, proto := range bsnet.supportedProtocols {
bsnet.host.SetStreamHandler(proto, bsnet.handleNewStream)
}

bsnet.host.Network().Notify((*netNotifiee)(bsnet))
bsnet.connectEvtMgr.Start()

}
```
It seem that Notify event of bsnet may be happen after the dial result return of the code:
```
bsnet.host.Network().Notify((*netNotifiee)(bsnet))
```

`conn, err := w.s.addConn(res.Conn, network.DirOutbound)`

file dial_worker.go of go-libp2p@v0.20.3
```
if res.Conn != nil {
// we got a connection, add it to the swarm

//debug.PrintStack()
//time.Sleep(time.Second*1)
conn, err := w.s.addConn(res.Conn, network.DirOutbound)
if err != nil {
// oops no, we failed to add it to the swarm
res.Conn.Close()
w.dispatchError(ad, err)
continue loop
}

// dispatch to still pending requests
for _, reqno := range ad.requests {
pr, ok := w.requests[reqno]
if !ok {
// it has already dispatched a connection
continue
}

pr.req.resch <- dialResponse{conn: conn}
delete(w.requests, reqno)
}

ad.conn = conn
ad.requests = nil

continue loop
}

```
So the bsnet may not feel this connection event unless disconect and connect again。
