[ Upstream commit 0be04b5fa62a82a9929ca261f6c9f64a3d0a28da ]
The switch clears the ARL_SRCH_STDN bit when the search is done, i.e. it
finished traversing the ARL table.
This means that there will be no valid result, so we should not attempt
to read and process any further entries.
We only ever check the validity of the entries for 4 ARL bin chips, and
only after having passed the first entry to the b53_fdb_copy().
This means that we always pass an invalid entry at the end to the
b53_fdb_copy(). b53_fdb_copy() does check the validity though before
passing on the entry, so it never gets passed on.
On < 4 ARL bin chips, we will even continue reading invalid entries
until we reach the result limit.

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.
