Wesley Sheng ba8a39820d switchtec: Increase PFF limit from 48 to 255
The Switchtec devices supports two PCIe Function Frameworks (PFFs) per
upstream port (one for the port itself and one for the management endoint),
and each PFF may have up to 255 ports.  Previously the driver only
supported 48 of those ports, and the SWITCHTEC_IOCTL_EVENT_SUMMARY ioctl
only returned information about those 48.

Increase SWITCHTEC_MAX_PFF_CSR from 48 to 255 so the driver supports all
255 possible ports.

Rename SWITCHTEC_IOCTL_EVENT_SUMMARY and associated struct
switchtec_ioctl_event_summary to SWITCHTEC_IOCTL_EVENT_SUMMARY_LEGACY and
switchtec_ioctl_event_summary_legacy with so existing applications work
unchanged, supporting up to 48 ports.

Add replacement SWITCHTEC_IOCTL_EVENT_SUMMARY and struct
switchtec_ioctl_event_summary that new and recompiled applications support
up to 255 ports.

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.
