Tristram Ha 8803d2f90c net: dsa: microchip: Fix reserved multicast address table programming 
[ Upstream commit 96baf482ca ]

KSZ9477/KSZ9897 and LAN937X families of switches use a reserved multicast
address table for some specific forwarding with some multicast addresses,
like the one used in STP.  The hardware assumes the host port is the last
port in KSZ9897 family and port 5 in LAN937X family.  Most of the time
this assumption is correct but not in other cases like KSZ9477.
Originally the function just setups the first entry, but the others still
need update, especially for one common multicast address that is used by
PTP operation.

LAN937x also uses different register bits when accessing the reserved
table.

Fixes: 457c182af5 ("net: dsa: microchip: generic access to ksz9477 static and reserved table")

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 reStructuredText 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.
