[PATCH mptcp-next 0/6] refactor MPTCP socket option handling

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

This series restructures MPTCP socket option implementation to improve
maintainability and consistency. We introduce dedicated helper functions
for different option levels (SOL_SOCKET, SOL_IP, SOL_IPV6, SOL_TCP) and
propagation scopes (first subflow vs. all subflows), addressing current
code fragmentation.

Geliang Tang (6):
  mptcp: add helper for setsockopt on first subflow only
  mptcp: handle SOL_SOCKET options on first subflow only
  mptcp: refactor IP socket option handling for first subflow
  mptcp: extract IPv6 socket option handling for first subflow
  mptcp: handle SOL_TCP options on all subflows
  mptcp: handle IP socket options on all subflows
