Message-ID: <20240304133827.1989736-12-matttbe@kernel.org>

From: Geliang Tang <tanggeliang@kylinos.cn>

commit 7092dbee23282b6fcf1313fc64e2b92649ee16e8 upstream.

Now both a v4 address and a v4-mapped address are supported when
destroying a userspace pm subflow, this patch adds a second subflow
to "userspace pm add & remove address" test, and two subflows could
be removed two different ways, one with the v4mapped and one with v4.

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/387
