Hao Chen 8778372118 net: hns3: fix ethtool tx copybreak buf size indicating not aligned issue
When use ethtoool set tx copybreak buf size to a large value
which causes order exceeding 10 or memory is not enough,
it causes allocating tx copybreak buffer failed and print
"the active tx spare buf is 0, not enabled tx spare buffer",
however, use --get-tunable parameter query tx copybreak buf
size and it indicates setting value not 0.

So, it's necessary to change the print value from setting
value to 0.

Set kinfo.tx_spare_buf_size to 0 when set tx copybreak buf size failed.

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.
