st_scsi_kern_execute is a helper function to perform SCSI commands synchronously. It supports data transfer with a liner in-kernel buffer (not scatter gather). st_scsi_kern_execute internally uses scsi_execute(). The majority of st_do_scsi can be replaced with st_scsi_kern_execute. This is a preparation for rewriting st_do_scsi to remove obsolete scsi_execute_async(). Signed-off-by:

This moves st_request initialization code to st_allocate_request() form st_do_scsi(). This is a preparation for making st_allocate_request() usable for everyone, not only st_do_scsi(). Signed-off-by:

Per the recent discussions at the Linux Plumbers Conference, when enabling MSI or MSI-X, generate a test interrupt to verify the interrupt routing is working properly. If the test interrupt fails, fall back to MSI first, and if that fails as well, to INTx. If the interrupt test fails with INTx, log an error and fail the PCI probe. Also changed the use of spin_(lock|unlock) to the _irq(save|restore) variants in the interrupt handlers because with multi-message MSI-X, both interrupt handlers can now run in parallel.

- Avoid polling HBA Error Attention when HBA's PCI channel is offline due to PCI EEH - Fix handling of RSCN with non-zero event qualifiers - Remove unnecessary sleeps during HBA initialization which slow down driver load - Fix internal and external loopback on FCoE HBAs - Fix incorrect decrement of cmd_pending count in lpfc_queuecomand error path - Fix reporting of port busy events to management application - Rename lpfc_adjust_queue_depth() to lpfc_rampdown_queue_depth() for consistency with its partner lpfc_rampup_queue_depth() - Delete redundant lpfc_cmd->start_time = jiffies assignment in lpfc_queuecommand() - Fix handling for ELS, mailbox and heartbeat time outs in the worker thread by removing unnecessary checking of the work_port_events flags. - Fix NULL pointer dereference in lpfc_prep_els_iocb - In lpfc_device_recov_npr_node(), move clearing of NLP_NPR_2B_DISC flag after call to lpfc_cancel_retry_delay_tmo() to keep targets-in-discovery count correct - Remove lpfc_probe_one()'s call to scsi_scan_host() which could cause concurrent SCSI scans to step on each other Signed-off-by:

The phba hbq_get address was setup before the HBA reported support for Interrupt Enable Block (INB). This caused loopback tests to fail after all HBQs had been used once. Moved setting of hba_get until after config port mailbox command completes. Signed-off-by:

- Fix lock up on rmmod with vports defined by having lpfc_pci_remove_one() invoke fc_vport_terminate() to remove all the vports before invoking fc_remove_host() for the physical port - Fix echotest failure when NPIV is enabled - Add the vport_disable function to the physical port's transport template to make the vport disable attribute visible - Set the vport state to DISABLE on create if the disable flag is true - Call lpfc_alloc_sysfs_attr() for vports so that statistical data collection works on them - Support setting a vport's symbolic name via sysfs by writing to /sys/class/fc_vport/vportX/symbolic_name - Fix create vport fails when link is down or in loop mode. Should be able to be create vports any time NPIV is enabled - Fix slow vport deletes when deleting multiple vports at once Signed-off-by:

This patch changes scsi_probe_lun() to retry INQUIRY if the device has not actually sent back any INQUIRY data, This enables the Thecus N2050 storage device to work better. The firmware on that device starts up strangely; it sends no data in response to the initial INQUIRY, and it sends the INQUIRY information in response to the followup REQUEST SENSE. But after that it works better, so retrying the INQUIRY is enough to get it going. Signed-off-by:

scsi_execute() and scsi_execute_req() discard the residual length information. Some callers need it. This adds residual argument (optional) to scsi_execute and scsi_execute_req. Signed-off-by:

Adds a delay prior to retrying a failed NPIV login. This fixes a scenario if the backing fibre channel adapter is getting reset due to an EEH event, NPIV login will fail. Currently, ibmvfc retries three times very quickly, resets the CRQ and tries one more time. If the adapter is getting reset due to EEH, this isn't enough time. This adds a delay prior to retrying a failed NPIV login and also increments the number of retries. Signed-off-by:

cxgb3i does not offload the processing of the header, but it will always process the padding. This patch adds a padding offload flag to detect when the LLD supports this. The patch also modifies the header processing so that we do not try to read/bypass the header dugest in the skb. cxgb3i will not include it with the header like with other offload cards.

Mgmt setup used to not fail so we did not have to check the return value. Now with cxgb3i it can so this has us pass up a error. Signed-off-by:

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. Signed-off-by:

As explained in the previous mails, cxgb3i needs iscsi_tcp's r2t/data_out and data_in procesing so this just moves functions that both drivers want to use to a new module libiscsi_tcp. The next patch will hook iscsi_tcp in. Signed-off-by:
