get undefined: syscall.Stat_t when use quic in the windows environment

[wenchaopeng]

I have a problem with quic in the windows environment
my code is like this:

        sourceMultiAddr, _ := ma.NewMultiaddr(node.cfg.P2P.Listen)
	q,err:=quic.NewTransport(node.privateKey)
	if err!=nil{
		return err
	}
	host, err := libp2p.New(
		node.ctx,
		libp2p.ListenAddrs(sourceMultiAddr),
		libp2p.Identity(node.privateKey),
		libp2p.BandwidthReporter(node.reporter),
		libp2p.Ping(false),
		libp2p.Transport(q),
	)
	if err != nil {
		return err
	}

the error log is like this：

pls help me,thanks you!

It seems like netlink doesn't support Windows, there's even a (three years old) issue for that: vishvananda/netlink#146. I confirmed that it's not possible to build it on Windows.

The only fix for this I can think of is to not even import netlink on Windows. This won't be a trivial thing though, since reuse contains a netlink.Handle, and it's expected to be nil on non-Linux systems, it will still pull in netlink and cause the build error.
So we'd probably have to refactor reuse in a base struct that works on all OSes, and extend this struct with the netlink capabilities in a struct that's only built on Linux on OSX.

I'm quite busy at the moment and won't have time to work on this any time soon, but I'd be happy to review a PR.

This is making it impossible to update QUIC in libp2p/go-ipfs which is preventing us from deploying it to infra.
