Thanks, I suspected something like that existed. Edit: The Wikipedia article says: "By 1999, several vendors supported receiving pause frames, but fewer implemented sending them.[4][5] Pause frames have several disadvantages.". Any idea what the situation is like today?

I believe L2 flow control is pretty common. Of course you're usually not going to see them even when using Wireshark etc., because they're handled at the MAC hardware level. I'm not aware how to reliably determine whether link partner has L2 flow control / pause frames enabled. But at least you can check whether it's locally enabled: Linux: ethtool -a eth0 macOS: ifconfig en0 | grep media Windows Powershell: Get-NetAdapterAdvancedProperty Alternatively you can check Control Panel / Network Connections / right click adapter + select Properties / click Configure / Advanced tab / Flow Control value. Note that above only applies to wired ethernet, not wlan.
