Jakub Kicinski ebe3bdc435 tools: ynl: throw a more meaningful exception if family not supported
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:

Traceback (most recent call last):
  File "/home/kicinski/devel/linux/./tools/net/ynl/cli.py", line 52, in <module>
    main()
  File "/home/kicinski/devel/linux/./tools/net/ynl/cli.py", line 31, in main
    ynl = YnlFamily(args.spec, args.schema)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/kicinski/devel/linux/tools/net/ynl/lib/ynl.py", line 364, in __init__
    raise Exception(f"Family '{self.yaml['name']}' not supported by the kernel")
Exception: Family 'netdev' not supported by the kernel

README

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.
