[PATCH net-next v2 0/4] mptcp: misc. features for v6.18

["Matthieu Baerts (NGI0)" <matttbe@kernel.org>]

This series contains 4 independent new features:

- Patch 1: use HMAC-SHA256 library instead of open-coded HMAC.

- Patch 2: selftests: check for unexpected fallback counter increments.

- Patches 3-4: record subflows in RPS table, for aRFS support.

Changes in v2:
- Drop previous patches 2 ("mptcp: make ADD_ADDR retransmission timeout
  adaptive") + 3 ("selftests: mptcp: remove add_addr_timeout settings"):
  They were introducing instabilities in the selftests.
- Rebased. Other patches have not been modified.
- Link to v1: https://lore.kernel.org/r/20250901-net-next-mptcp-misc-feat-6-18-v1-0-80ae80d2b903@kernel.org
