Colin's commit went a step further and protected tun.incomingPacket with
a lock on shutdown, but let's see if the tun.stack.Close() call actually
solves that on its own.

tun/netstack: remove usage of pkt.IsNil()2025-05-05T13:05:35ZJason A. DonenfeldJason@zx2c4.com2025-05-04T15:54:57Zurn:sha1:e3c1354d27f53462801e1b86b4275699a6f9fdac
Since 3c75945fd ("netstack: remove PacketBuffer.IsNil()") this has been
invalid. Follow the replacement pattern of that commit.
The old definition inlined to the same code anyway:
func (pk *PacketBuffer) IsNil() bool {
return pk == nil
}

tun/netstack: enable TCP Selective Acknowledgements2023-03-10T13:52:39ZJordan Whitedjordan@tailscale.com2023-03-09T19:06:01Zurn:sha1:5819c6af28239b973958a8d197f9e39926e7b9f1
Enable TCP SACK for the gVisor Stack used in tun/netstack. This can
improve throughput by an order of magnitude in the presence of packet
loss.

conn, device, tun: implement vectorized I/O plumbing2023-03-10T13:52:13ZJordan Whitedjordan@tailscale.com2023-03-02T22:48:02Zurn:sha1:3bb8fec7e41fcc2138ddb4cba3f46100814fc523
Accept packet vectors for reading and writing in the tun.Device and
conn.Bind interfaces, so that the internal plumbing between these
interfaces now passes a vector of packets. Vectors move untouched
between these interfaces, i.e. if 128 packets are received from
conn.Bind.Read(), 128 packets are passed to tun.Device.Write(). There is
no internal buffering.
Currently, existing implementations are only adjusted to have vectors
of length one. Subsequent patches will improve that.
Also, as a related fixup, use the unix and windows packages rather than
the syscall package when possible.
