Michal Kubecek 0c84979c95 ethtool: provide channel counts with CHANNELS_GET request
Implement CHANNELS_GET request to get channel counts of a network device.
These are traditionally available via ETHTOOL_GCHANNELS ioctl request.

Omit attributes for channel types which are not supported by driver or
device (zero reported for maximum).

v2: (all suggested by Jakub Kicinski)
  - minor cleanup in channels_prepare_data()
  - more descriptive channels_reply_size()
  - omit attributes with zero max count

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.
