Peng Li 3a5a5f06d4 net: hns3: revert to old channel when setting new channel num fail
After setting new channel num, it needs free old ring memory and
allocate new ring memory. If there is no enough memory and allocate
new ring memory fail, the ring may initialize fail. To make sure
the network interface can work normally, driver should revert the
channel to the old configuration.

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.
