Taehee Yoo cb32707497 selftests: net: amt: wait longer for connection before sending packets
[ Upstream commit 04708606fd ]

Both send_mcast4() and send_mcast6() use sleep 2 to wait for the tunnel
connection between the gateway and the relay, and for the listener
socket to be created in the LISTENER namespace.

However, tests sometimes fail because packets are sent before the
connection is fully established.

Increase the waiting time to make the tests more reliable, and use
wait_local_port_listen() to explicitly wait for the listener socket.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
