- Patch 1: better handle DSS corruptions from a bugged peer: reducing warnings, doing a fallback or a reset depending on the subflow state. For >= v5.7.
- Patch 2: fix DSS corruption due to large pmtu xmit, where MPTCP was not taken into account. For >= v5.6.
- Patch 3: fallback when MPTCP opts are dropped after the first data packet, instead of resetting the connection. For >= v5.6.
- Patch 4: restrict the removal of a subflow to other closing states, a better fix, for a recent one. For >= v5.10.
