* [SCSI] qla2xxx: Use 'proper' DID_* status code for dropped-frame scenarios.Andrew Vasquez2009-06-08
| | | | | | | | | | | The SCSI-midlayer's fast-fail codes consider an DID_ERROR status as a driver-error and the failed I/O would then be retried in the midlayer without being fast-failed to dm-multipath. DID_BUS_BUSY status returns would induce unneeded path-failures events being propagated to the DM/MD.

* [SCSI] fcoe: removes fcoe_watchdogVasu Dev2009-06-08
| | | | | | | | | | | | | | | | | | | Removes periodic fcoe_watchdog timer used across all fcoe interface maintained in fcoe_hostlist instead added new fcoe_queue_timer per fcoe interface. Added timer is armed only when some pending skb need to be flushed as oppose to periodic 1 second fcoe_watchdog, since now fcoe_queue_timer is used on demand thus set this to 2 jiffies. Now fcoe_queue_timer is much simple than fcoe_watchdog using lock to process all fcoe interface from fcoe_hostlist. I noticed +ve performance result with using 2 jiffies timer as this helps flushing fcoe_pending_queue quickly.

* [SCSI] fcoe: reduces lock cost when adding a new skb to fcoe_pending_queueVasu Dev2009-06-08
| | | | | | | | | | | | | | | | | | | Currently fcoe_pending_queue.lock held twice for every new skb adding to this queue when already least one pkt is pending in this queue and that is not uncommon once skb pkts starts getting queued here upon fcoe_start_io => dev_queue_xmit failure. This patch moves most fcoe_pending_queue logic to fcoe_check_wait_queue function, this new logic grabs fcoe_pending_queue.lock only once to add a new skb instead twice as used to be. I think after this patch call flow around fcoe_check_wait_queue calling in fcoe_xmit is bit simplified with modified fcoe_check_wait_queue function taking care of adding and removing pending skb in one function.

* [SCSI] libfcoe: fip: fix non-FIP-mode FLOGI state after reset.Joe Eykholt2009-06-08
| | | | | | | | | | | | | | | When a reset is sent using fcoeadm on a non-FIP mode NIC, there's no link flap, so the fcoe_ctlr stays in non-FIP mode. In that case, FIP wasn't setting the flogi_oxid or map_dest flag, causing the FLOGI to be sent with the both wrong source MAC and the wrong destination MAC address, causing it to fail. This leads to a non-functioning HBA until a link flap or instance delete/create. Signed-off-by: Joe Eykholt <jeykholt@cisco.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

* [SCSI] ibmvfc: Improve LOGO/PRLO ELS handlingBrian King2009-06-08
| | | | | | | | | | | | | There are several scenarios where the ibmvfc driver needs to try to log back into a target on the fabric. Today when these events occur, we simply go through re-discovery for all attached targets, assuming that either the query of the name server or an ADISC will indicate we might need to log back into the target, which doesn't work for all scenarios. Fix this by taking note of the affected target(s) in these conditions and ensuring we try to PLOGI back into the target.

* [SCSI] ibmvfc: Improve device rediscoveryBrian King2009-06-08
| | | | | | | | | | | For certain scenarios during device rediscovery, we detect we need to log back into a target. Currently we do just that - PLOGI/PRLI back into the target.

* [SCSI] ibmvfc: Add flush on halt supportBrian King2009-06-08
| | | | | | | | | | | | | The virtual I/O server controlling the NPIV adapter associated with a virtual fibre channel adapter can send a HALT event to the client. When this occurs, the client can no longer send commands until a RESUME is received. By adding support for flush on halt, we will get all of our outstanding commands flushed back before the Virtual I/O server enters the halt state, eliminating potential command timeouts for outstanding commands which might occur if we did not support this feature.

* [SCSI] ibmvfc: Add support for NPIV LogoutBrian King2009-06-08
| | | | | | | | | | | | This patch adds support for a new command supported by the Virtual I/O Server, NPIV Logout. The command will abort all outstanding commands and log out of the fabric. Currently, the only way to do this is by breaking the CRQ, which can take a fairly long time when lots of commands are outstanding. The NPIV Logout commands provides a mechanism to accomplish virtually the same function, but is much faster.

* [SCSI] ibmvfc: Reduce error logging noiseBrian King2009-06-08
| | | | | | | | | | | | | | The ibmvfc driver currently logs errors during discovery for several transient fabric errors, which generally get retried. If retries do not work, we see multiple errors in the log. If retries do work, we see errors in the log which may be confusing since the retry worked. This patch enhances the discovery time error logging to only log errors for command failures during discovery if all allowed retries have been used up. The existing behavior of logging all failures can be restored by setting the hosts log_level to a value of 3 or greater.

| | | | | | | | | | | Adds new hardware and interface definitions. Adds new interface routines - utilizing the reorganized layout of the driver. Adds SLI-4 specific functions for attachment, initialization, teardown, etc. Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] lpfc 8.3.2 : Reorganization for SLI4James Smart2009-06-08
| | | | | | | | | | | | | | | Preps the organization of the driver so that the bottom half, which interacts with the hardware, can share common code sequences for attachment, detachment, initialization, teardown, etc with new hardware. For very common code sections, which become specific to the interface type, the driver uses an indirect function call. The function is set at initialization. For less common sections, such as initialization, the driver looks at the interface type and calls the routines relative to the interface.

* [SCSI] mpt2sas: using the same naming convention for all static functionEric Moore2009-05-23
| | | | | | | | | This fix's is for all local function so their name has the "_" preceeding the module name, then function name. Most the code is already is using this naming convention.

* [SCSI] mpt2sas: add query task support for MPT2COMMAND ioctlEric Moore2009-05-23
| | | | | | | | | | This patch will find an active mid for a query_task request via the ioctl path. This code is already there for task_abort, so this patch combining code using the same fuction _ctl_set_task_mid(), previously _ctl_do_task_abort().

* [SCSI] mpt2sas: LUN Reset SupportEric Moore2009-05-23
| | | | | | | | | | | | Adding new eh_target_reset_handler for target reset. Change the eh_device_reset_handler so its sending MPI2_SCSITASKMGMT_TASKTYPE_LOGICAL_UNIT_RESET, instead of MPI2_SCSITASKMGMT_TASKTYPE_TARGET_RESET. Add new function _scsih_scsi_lookup_find_by_lun as a sanity check to insure I_T_L commands are completed upon completing lun reset.

| | | | | | | | | | | Keep the information about the device and model id in zfcp_ccw. This requires an additional helper function to check for the privileged cfdc subchannel, but it allows the removal of the redundant defines from the zfcp_def header file.
