In early days of YNL development dumping the NlMsg on errors
was quite useful, as the library itself could have been buggy.
These days increasingly the NlMsg is just taking up screen space
and means nothing to a typical user. Try to format the errors
more in line with how YNL C formats its errors strings.
Before:
$ ynl --family ethtool --do channels-set --json '{}'
Netlink error: Invalid argument
nl_len = 44 (28) nl_flags = 0x300 nl_type = 2
error: -22
extack: {'miss-type': 'header'}
$ ynl --family ethtool --do channels-set --json '{..., "tx-count": 999}'
Netlink error: Invalid argument
nl_len = 88 (72) nl_flags = 0x300 nl_type = 2
error: -22
extack: {'msg': 'requested channel count exceeds maximum', 'bad-attr': '.tx-count'}
After:
$ ynl --family ethtool --do channels-set --json '{}'
Netlink error: Invalid argument {'miss-type': 'header'}
$ ynl --family ethtool --do channels-set --json '{..., "tx-count": 999}'
Netlink error: requested channel count exceeds maximum: Invalid argument {'bad-attr': '.tx-count'}

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 reStructuredText 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.
