Similarly to what has been done in8b4c3cdd9d("net: sched: Add policy validation for tc attributes"), fix classifier code to add validation of TCA_CHAIN and TCA_KIND netlink attributes. tested with: # ./tdc.py -c filter v2: Let sch_api and cls_api share nla_policy they have in common, thanks to David Ahern. v3: Avoid EXPORT_SYMBOL(), as validation of those attributes is not done by TC modules, thanks to Cong Wang. While at it, restore the 'Delete / get qdisc' comment to its orginal position, just above tc_get_qdisc() function prototype.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
