From 262ef63627977acb7d8dd38c4f0f290bf49fbbfd Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 2 Dec 2008 00:32:13 -0600 Subject: [SCSI] libiscsi: allow drivers to modify the itt sent to the target bnx2i and cxgb3i need to encode LLD info in the itt so that the firmware/hardware can process the pdu. This patch allows the LLDs to encode info in the task->hdr->itt that they setup in the alloc_pdu callout (any resources that are allocated can be freed with the pdu in the cleanup_task callout). If the LLD encodes info in the itt they should implement a parse_pdu_itt callout. If parse_pdu_itt is not implemented libiscsi will do the right thing for the LLD.
