Retr - column in tcp result not showing

[citytoast]

Hey,

I'm doing some troubleshooting (probably because of some old and too long cables) and while using -u I can see the package loss.
But when doing tcp the "Retr" column wont show, neither on the client nor on the server.

I'm using the latest Windows build (https://github.com/ar51an/iperf3-win-builds).

Anyone knows why? I tried using -V but still didn't show.

Client:

Server:

The retransmissions information is taken from the TCP Info, but iperf3 does not support Windows TCP info as shown by the has_tcpinfo() code below. This may be just because iperf3 is not supported officially by iperf3. To add the support, CygWin should support TCP Info. At least in the past there were issues with this, but it may be that now CygWin doe support TCP info. If this si the case, then maybe the support can be added.
