Subject: [PATCH bpf-next v4 4/6] bpf: selftests: Support not connecting client socket
Date:   Wed, 12 Jul 2023 17:43:59 -0600
Message-ID: <0b1b6665846b7e88f49db8fe4d929955a3aa69e7.1689203090.git.dxu@dxuuu.xyz>

Content-Transfer-Encoding: 8bit
Precedence: bulk

For connectionless protocols or raw sockets we do not want to actually
connect() to the server.
