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.
