Here are various fixes from Paolo, addressing very occasional issues on the sending side:
- Patch 1: drop an optimisation that could lead to timeout in case of race conditions. A fix for up to v5.11.
- Patch 2: fix stream corruption under very specific conditions. A fix for up to v5.13.
- Patch 3: restore MPTCP-level zero window probe after a recent fix. A fix for up to v5.16.
- Patch 4: new MIB counter to track MPTCP-level zero windows probe to help catching issues similar to the one fixed by the previous patch.
