The Interface class of the router is an abstraction for NIC client sessions, NIC server sessions, and Uplink sessions. Nonetheless, Interface generally used to use the packet stream types of the Nic namespace and it worked because the Uplink packet stream types are factually the same (the are typedef'd from the same base type templates with the same parameters). The initial intention of this issue was to remove dependency on the diverse packet stream stream types from Interface. However, this turned out to be more tricky than thought. The Interface class calls function templates on the packet stream types, making a generic virtual interface impossible. And moving the calling code to the session classes as well would produce a lot of redundancy. Therefore, this commit removes only the use of the Nic namespace in the interface.* files by typedef'ing the packet stream types from the generic Genode type templates with the same parameters as in Nic and Uplink. Fixes #4385

Genode Operating System Framework
=================================
This is the source tree of the reference implementation of the Genode OS
architecture. For a general overview about the architecture, please refer to
the project's official website:
:Official project website for the Genode OS Framework:
[https://genode.org/documentation/general-overview]
The current implementation can be compiled for 8 different 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 the use of each of the kernels listed above 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 Genode website:
:Download the book "Genode Foundations":
[https://genode.org]
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:
