If a gateway can not receive any response to requests from a relay,
gateway resets status from SENT_REQUEST to INIT and variable about a
relay as well. And then it should start the full establish step
from sending a discovery message and receiving advertisement message.
But, after failure in amt_req_work() it continues sending a request
message step with flushed(invalid) relay information and sets SENT_REQUEST.
So, a gateway can't be established with a relay.
In order to avoid this situation, it stops sending the request message
step if it fails.

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 Restructured Text 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.
