Finn Thain 079e7e7758 net/sonic: Fix command register usage
commit 27e0c31c5f27c1d1a1d9d135c123069f60dcf97b upstream.

There are several issues relating to command register usage during
chip initialization.

Firstly, the SONIC sometimes comes out of software reset with the
Start Timer bit set. This gets logged as,

    macsonic macsonic eth0: sonic_init: status=24, i=101

Avoid this by giving the Stop Timer command earlier than later.

Secondly, the loop that waits for the Read RRA command to complete has
the break condition inverted. That's why the for loop iterates until
its termination condition. Call the helper for this instead.

Finally, give the Receiver Enable command after clearing interrupts,
not before, to avoid the possibility of losing an interrupt.

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.
