+ - Distribution and version (or `cat /etc/os-release`): **TODO**
+ - MPTCP sysctl (`sysctl net.mptcp`):
+```
+TODO

+**Up-to-date kernel?**
+<!-- Did you try to reproduce the issue with ideally the last stable kernel version, or at least the last LTS version (or the development version using our `export` branch?
+See https://www.kernel.org for the supported versions -->
+
+**Additional context**
+<!--
+Add any other context about the problem here.
+Note: It might help to get the output of  `ip mptcp monitor` while reproducing the issue, in addition to the output from these commands executed just before **and** after the issue:
+```
+ss -ManiH
+nstat
+```
+Packet traces (TCPDump / WireShark) can be helpful too. See https://www.mptcp.dev/debugging.html for more details.
+mptcpd's `mptcp-get-debug` script (mptcpd >= 0.13) can help to collect such infos: https://raw.githubusercontent.com/multipath-tcp/mptcpd/refs/heads/main/scripts/mptcp-get-debug
