Masahisa KOJIMA 9a00b697ce net: socionext: reset hardware in ndo_stop
When the interface is down, head/tail of the descriptor
ring address is set to 0 in netsec_netdev_stop().
But netsec hardware still keeps the previous descriptor
ring address, so there is inconsistency between driver
and hardware after interface is up at a later time.
To address this inconsistency, add netsec_reset_hardware()
when the interface is down.

In addition, to minimize the reset process,
add flag to decide whether driver loads the netsec microcode.
Even if driver resets the netsec hardware, netsec microcode
keeps resident on RAM, so it is ok we only load the microcode
at initialization.

This patch is critical for installation over network.

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.
