In the CFF flood mode, the driver has to allocate a table within PGT, which holds flood vectors for router subport FIDs. For LAGs, these flood vectors have to obviously be maintained dynamically as port membership in a LAG changes. But even for physical ports, the flood vectors have to be kept valid, and may not contain enabled bits corresponding to non-existent ports. It is therefore not possible to precompute the port part of the RSP table, it has to be maintained as ports come and go due to splits. To support the RSP table maintenance, add to FID ops two new ops: fid_port_init and fid_port_fini, for when a port comes to existence, or joins a lag, and vice versa. Invoke these ops from mlxsw_sp_port_fids_init() and mlxsw_sp_port_fids_fini(), which are called when port is added and removed, respectively. Also add two new hooks for LAG maintenance, mlxsw_sp_fid_port_join_lag() / _leave_lag() which transitively call into the same ops. Later patches will actually add the op implementations themselves, this just adds the scaffolding.

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.
