172 * tgt_rscn_delay - delay in kicking off RSCN processing
173 * (nameserver queries) after receiving an RSCN on the target.
174 * This prevents thrashing of nameserver requests due to a huge burst of
175 * RSCNs received in a short period of time.
176 * Note: this is only valid when target RSCN handling is enabled -- see

182 * tgt_rscn_period - determines maximum frequency when processing
183 * back-to-back RSCNs; e.g. if this value is 30, there will never be
184 * any more than 1 RSCN handling per 30s window. This prevents
185 * initiators on a faulty link generating many RSCN from causing the
186 * target to continually query the nameserver.
