OSM can also load SA DB from file, but then it also stays in this static SA configuration. The following patch series improves SA DB persistence: 1/3: Added option to load SA DB only on the first master heavy sweep. After that SA goes to the usual (dynamic) mode of operation 2/3: Added option to dump SA DB on every sweep (both light and heavy), regardless of the verbosity level. 3/3: Optimize SA DB dumping: added 'dirty' flag to the SA struct to denote that SA DB was modified since the last dump. SA DB will be dumped only if the DB is dirty. -- Yevgeny -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
