[PATCH net-next 0/2] mptcp: track more fallback cases

From: Matthieu Baerts (NGI0)
Date: Wed Jul 23 2025 - 10:32:52 EST


This series has two patches linked to fallback to TCP:

- Patch 1: additional MIB counters for remaining error code paths around
fallback

- Patch 2: remove dedicated pr_debug() linked to fallback now that
everything should be covered by dedicated MIB counters.
