Message-Id: <20231128-send-net-next-2023107-v4-5-8d6b94150f6b@kernel.org> Date: Tue, 28 Nov 2023 15:18:49 -0800 From: Mat Martineau <martineau@...nel.org> To: Matthieu Baerts <matttbe@...nel.org>, "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com> Cc: netdev@...r.kernel.org, mptcp@...ts.linux.dev, Mat Martineau <martineau@...nel.org>, Geliang Tang <geliang.tang@...e.com> Subject: [PATCH net-next v4 05/15] selftests: mptcp: userspace pm create id 0 subflow From: Geliang Tang <geliang.tang@...e.com> This patch adds a selftest to create id 0 subflow. Pass id 0 to the helper userspace_pm_add_sf() to create id 0 subflow. chk_mptcp_info shows one subflow but chk_subflows_total shows two subflows in each namespace.
