cli.py currently throws a pure KeyError if kernel doesn't support
a netlink family. Users who did not write ynl (hah) may waste
their time investigating what's wrong with the Python code.
Improve the error message:
Traceback (most recent call last):
File "/home/kicinski/devel/linux/tools/net/ynl/lib/ynl.py", line 362, in __init__
self.family = GenlFamily(self.yaml['name'])
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/kicinski/devel/linux/tools/net/ynl/lib/ynl.py", line 331, in __init__
self.genl_family = genl_family_name_to_id[family_name]
~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^
KeyError: 'netdev'
During handling of the above exception, another exception occurred:

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.
