When add_addr_timeout was set to 0, this caused the ADD_ADDR to be retransmitted immediately, which looks like a buggy behaviour. Instead, interpret 0 as "no retransmissions needed".
The documentation is updated to explicitly state that setting the timeout to 0 disables retransmission.
Fixes: 93f323b9cccc ("mptcp: add a new sysctl add_addr_timeout")
This commit is not in the 5.10-stable tree: it has been introduced in v5.11. No need to backport it to v5.10 then :)
Cheers, Matt
