Subject: [PATCH] selftests/net: replace AF_MAX with INT_MAX in socket.c
Date:   Mon, 16 Sep 2019 12:03:37 -0300
Message-Id: <20190916150337.18049-1-marcelo.cerri@canonical.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use INT_MAX instead of AF_MAX, since libc might have a smaller value
of AF_MAX than the kernel, what causes the test to fail.
