In order to transmit the STP BPDU packet to the CPU port, the STP address 01-80-c2-00-00-00 has to be added to static alu table for ksz8795 series switch. For the ksz9477 switch, there is reserved multicast table which handles forwarding the particular set of multicast address to cpu port. So enabling the multicast reserved table and updated the cpu port index. The stp addr is enabled during the setup phase using the enable_stp_addr pointer in struct ksz_dev_ops.

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.
