The BCM531x5 and BCM539x families require that the IMP port be enabled within the management page and that management mode (SM_SW_FWD_MODE) be turned on. Once this is done, everything works as expected, including multicast with standalone DSA devices or bridge devices. Because such switches are frequencly cascaded with other internal Broadcom switches on which we want to enable Broadcom tags, update b53_can_enable_brcm_tags() to check the kind of DSA master tagging protocol being used, if it is one of the two supported Broadcom tagging protocols, force DSA_TAG_PROTO_NONE.

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.
