[ Upstream commit 287d35405989cfe0090e3059f7788dc531879a8d ]

Recently, CONFIG_MPTCP_IPV6 no longer selects CONFIG_IPV6. As a
consequence, if CONFIG_MPTCP_IPV6=y is added to the kconfig, it will no
longer ensure CONFIG_IPV6=y. If it is not enabled, CONFIG_MPTCP_IPV6
will stay disabled and selftests will fail.

I think Sasha wanted to drop this patch [1]. But as I said earlier [2], this patch is not wrong, it is just not needed in v5.9 because the "Fixes" commit 010b430d5df5 ("mptcp: MPTCP_IPV6 should depend on IPV6 instead of selecting it") is not in v5.9.

I guess it is certainly easier to keep it because it is not wrong and doesn't hurt.
