So far, this test used dynamic_rom for the re-configuration of the nic router and tested for the expected ping results by inspecting the log with the run tool. However, this approach had two issues: * Timing differs significantly on different targets and so the dynamic_rom had the difficult task of compensating with heuristics without bloating the test duration too much. * In case of a failing test, it was difficult to determine the cause as the test kept running and produced output for quite some time and there was also no specific error message but only a generic timeout. These two issues are now fixed by introducing a test component that listens to the ping-result report and manages the nic router configuration. The new component exits early on failure and provides information on the error circumstances. Furthermore, the component advances to the next test step only after having seen the expected result of the active test step and thereby removes the need for heuristics about target timing. Fixes #5192

Genode Operating System Framework
=================================
This is the source code of Genode, which is a framework for creating
component-based operating systems. It combines capability-based security,
microkernel technology, sandboxed device drivers, and virtualization with
a novel operating system architecture. For a general overview about the
architecture, please refer to the project's official website:
:Website for the Genode OS Framework:
[https://genode.org/documentation/general-overview]
Genode-based operating systems can be compiled for a variety of kernels: Linux,
L4ka::Pistachio, L4/Fiasco, OKL4, NOVA, Fiasco.OC, seL4, and a custom "hw"
microkernel for running Genode without a 3rd-party kernel. Whereas the Linux
version serves us as development vehicle and enables us to rapidly develop the
generic parts of the system, the actual target platforms of the framework are
microkernels. There is no "perfect" microkernel - and neither should there be
one. If a microkernel pretended to be fit for all use cases, it wouldn't be
"micro". Hence, all microkernels differ in terms of their respective features,
complexity, and supported hardware architectures.
Genode allows for the use of each of the supported kernels with a rich set of
device drivers, protocol stacks, libraries, and applications in a uniform way.
For developers, the framework provides an easy way to target multiple different
kernels instead of tying the development to a particular kernel technology. For
kernel developers, Genode contributes advanced workloads, stress-testing their
kernel, and enabling a variety of application use cases that would not be
possible otherwise. For users and system integrators, it enables the choice of
the kernel that fits best with the requirements at hand for the particular
usage scenario.
Documentation
#############
The primary documentation is the book "Genode Foundations", which is available
on the front page of the Genode website:
:Download the book "Genode Foundations":

The book describes Genode in a holistic and comprehensive way. It equips you
with a thorough understanding of the architecture, assists developers with the
explanation of the development environment and system configuration, and
provides a look under the hood of the framework. Furthermore, it contains the
specification of the framework's programming interface.
The project has a quarterly release cycle. Each version is accompanied with
detailed release documentation, which is available at the documentation
section of the project website:
