Like IB the SL to SC to VL maps are available via SMA queries on the local port. However, it is more secure if SMP queries are limited to root or management nodes. (This is also true in IB.) So requiring PSM, ie regular applications, to issue SMA queries on the local port is not appropriate as it precludes a more secure policy of restricting the umad interface. sysfs is IMO a reasonable interface to communicate these tables to regular user applications.
