Subject: selftests: mptcp: join: no RST when rm subflow/addr
From: Matthieu Baerts <matttbe@xxxxxxxxxx>
commit 2cfaa8b3b7aece3c7b13dd10db20dcea65875692 upstream.
Recently, we noticed that some RST were wrongly generated when removing
the initial subflow.
This patch makes sure RST are not sent when removing any subflows or any
addresses.
Fixes: c2b2ae3925b6 ("mptcp: handle correctly disconnect() failures")
