Subject: [PATCH net-next 6/6] selftests: mptcp: Add tests for userspace PM type
Date: Wed, 27 Apr 2022 15:50:02 -0700	[thread overview]
Message-ID: <20220427225002.231996-7-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: <20220427225002.231996-1-mathew.j.martineau@linux.intel.com>

These tests ensure that the in-kernel path manager is bypassed when
the userspace path manager is configured. Kernel code is still
responsible for ADD_ADDR echo, so also make sure that's working.

Tested-by: Geliang Tang <geliang.tang@suse.com>
Acked-by: Paolo Abeni <pabeni@redhat.com>
Co-developed-by: Matthieu Baerts <matthieu.baerts@tessares.net>
