Using jhash is a probably a good idea, the "improved" hash is broken and will cause reordering in some circumstances: return (h - q->dyn_min) * (q->hash_divisor - 1) / q->dyn_range; dyn_min, dyn_max and dyn_range, as their name suggests, are adjusted dynamically, so the hash function changes whenever one of these values changes, resulting in reordering of packets belonging to a single flow. _______________________________________________ LARTC mailing list [email protected] http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
