[PATCH net 0/4] mptcp: misc fixes for v7.1-rc3

From: Matthieu Baerts (NGI0)

Date: Fri May 01 2026 - 15:36:41 EST


Here are various unrelated fixes:

- Patch 1: increment the right MIB counter. A fix for v5.7.

- Patch 2: set the right MPTCP reset reason. A fix for v5.9.

- Patch 3: fix rx timestamp corruption when on MPTCP passive fastopen. A
fix for v6.2.

- Patch 4: increase sockopt seq after having set TCP_MAXSEG to propagate
it to newer subflows later. A fix for 6.17.
