Jonas Gorski 41ca514a9a net: dsa: b53: fix enabling ip multicast
[ Upstream commit c264294624e956a967a9e2e5fa41e3273340b089 ]

In the New Control register bit 1 is either reserved, or has a different
function:

    Out of Range Error Discard

    When enabled, the ingress port discards any frames
    if the Length field is between 1500 and 1536
    (excluding 1500 and 1536) and with good CRC.

The actual bit for enabling IP multicast is bit 0, which was only
explicitly enabled for BCM5325 so far.

For older switch chips, this bit defaults to 0, so we want to enable it
as well, while newer switch chips default to 1, and their documentation
says "It is illegal to set this bit to zero."

So drop the wrong B53_IPMC_FWD_EN define, enable the IP multicast bit
also for other switch chips. While at it, rename it to (B53_)IP_MC as
that is how it is called in Broadcom code.

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.
