[PATCH mptcp-next 0/3] mptcp: improve ADD_ADDR timeout handling

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

This series optimizes MPTCP's ADD_ADDR retransmission timeout:

1. Renames sysctl to add_addr_timeout_max for clearer semantics
2. Makes timeout adaptive to subflow RTT
3. Updates selftests for the rename

The adaptive timeout improves subflow establishment responsiveness
while maintaining reliability through the max timeout cap. The rename
provides better configuration clarity.

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/576
