From c807f64340932e19f0d2ac9b30c8381e1f60663a Mon Sep 17 00:00:00 2001 From: Jack Wang Date: Mon, 30 Sep 2013 10:09:05 +0200 Subject: [PATCH] ib_srpt: always set response for task management The SRP specification requires: "Response data shall be provided in any SRP_RSP response that is sent in response to an SRP_TSK_MGMT request (see 6.7). The information in the RSP_CODE field (see table 24) shall indicate the completion status of the task management function." So fix this to avoid the SRP initiator interprets task management functions that succeeded as failed.
