The device includes two main tables to support layer 2 multicast (i.e.,
MDB and flooding). These are the PGT (Port Group Table) table and the MPE
(Multicast Port Egress) table.
- PGT is {MID -> (bitmap of local_port, SPME index)}
- MPE is {(Local port, SMPE index) -> eVID}
In the legacy model, software did not interact with MPE table as it was
completely hidden in firmware. In the new model, software needs to
populate the table itself in order to map from {Local port, SMPE} to an
egress VID. This is done using the SMPE register.
Configure SMPE register when a {Local port, VID} are mapped/unmapped to a
802.1d and 802.1q emulated FIDs. The MPE table is not relevant for rFIDs as
firmware handles their flooding.

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.
