Fix SYSFS interface issues. - In the lpfc_sli4_pdev_status_reg_wait() routine, after initial 100ms delay following write to PHYSDEV_CONTROL register for the firmware reaction, check the RN bit and ERR bit of the SLIPORT_STATUS register. If none of them became 1, the previous PHYSDEV_CONTROL register should be considered failed due to lack of privilege and error for no permission should be returned immediately without getting into the wait for RDY bits on the SLIPORT_STATUS register. - Remove the driver check on dev->is_physfn before proceed to perform the PHYSDEV_CONTROL register write, and let the PCI function's privilege setting and driver handling of PHYSDEV_CONTROL register write failure to handle the reset-ability through the SLI port. - Added key to ctlreg_write to prevent unauthorized or unexpected write to the control register. - Change return to EACCES for sysfs access that are failed because hba_reset is disabled.

Fix HBA initialization issues - Swap all values that come from the firmware image on little endian systems. Created a new bf_get_be macro that does the same as the bf_get_le macro but for big endian data instead of little endian data. - Moved the incrementing of temp_offset after the copy fixed the write object loop to use temp_offset to figure out where the end of the image is instead of offset. - Added the necessary codes for properly bringing the driver instance offline and then trying to bring the port back online with the PCI function IP reset. If it fails to bring the SLI port back online, it will fall through to bringing the SLI port to HBA error offline. - Add a call in the probe_one_s3 and probe_one_s4 routines to get the Modeldesc - Change OCe50100 to OCe15100 - Made the error log also include the PCI BAR bitmap returned from kernel call pci_select_bars().

Fix issues pertaining to SCSI/FC protocol. - Allow frames destined to 0xFFFFFE to be processed by the driver by matching that DID with the physical port. - Call lpfc_sli_issue_iocb with context1 set to ndlp - In echo command accept function, adjust memcpy to limit memcpy to 1K - Set LPFC_SLI3_BG_ENABLED properly upon completion. - Skip the INIT_VFI call in lpfc_register_fcf if the FCF is already registered and go immediately to initial flogi. - use "status" variable instead of "ret" variable to hold the return of the fc_block_scsi_eh.

This patch adds a shutdown routine. It fixes a bug where when be2net and be2iscsi are both used be2iscsi was not cleaning up its resources properly causing be2net to fail to get loaded when the system is rebooted. Signed-off-by:

Fix be2iscsi driver to use a separate pointer for each irq action->name field and avoid display corruption in /proc/interrupts. The be2iscsi driver was using a single static array in a function for the irq action->name field. This results in garbage output from /proc/interrupts The pointer for action->name is garbage and scribbles the output on the screen. This patch fixes the problem: 156: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 PCI-MSI-X beiscsi_msix_0017 This patch is based on Prarit's patch here: http://www.spinics.net/lists/linux-scsi/msg52325.html but I have fixed up the failure paths and removed redundant check for !i suggested by Eike.

The Marvell Universal Message Interface (UMI) defines a messaging interface between host and Marvell products (Plato, for example). It considers situations of limited system resource and optimized system performance. UMI driver translates host request to message and sends message to FW via UMI, FW receives message and processes it, then sends response to UMI driver. FW generates an interrupt when it needs to send information or response to UMI driver Signed-off-by:

Some CD-ROMs fail to report a media change correctly. The specific one for this patch simply fails to respond to commands, then gives a UNIT ATTENTION after being reset which returns ASC/ASCQ 28/00. This is out of spec behaviour, but add a check in the eat CC/UA on reset path to catch this case so the CD-ROM will function somewhat properly.

1. Remove device database entry (ddb) state. 2. Remove device database (DDB) list building. With open-iscsi integration the logins to the target devices are handled by the user space. So the information of target is now maintained in the iscsi_session object. This is handled at libiscsi level so there is no need to maintain a list of DDBs in the qla4xxx LLD. 3. qla4xxx: Remove add_device_dynamically. Since autologin in FW is disabled with open-iscsi integration, driver will never get an AEN for which driver has not requested a DDB index. So remove the add_device_dynamically function. 4. Remove qla4xxx_tgt_dscvr Since firmware autologin is disabled this function will not work. Now user has the ability to do the target discovery and login to each target individually. Firwmare will not do the login on its own. 5. Remove relogin related code All relogin is handled by userspace now. qla4xxx just need to notify userspace of a connection failure, this triggers the relogin. 6. Remove add_session and alloc_session Now qla4xxx uses iscsi_session_setup that would do the necessary allocations for session and ddb_entry.

Add scsi_transport_iscsi hooks in qla4xxx to support iSCSI session management using iscsiadm. This patch is based on discussion here http://groups.google.com/group/open-iscsi/browse_thread/thread/e89fd888baf656a0# Now users can use iscsiadm to do target discovery and do login/logout to individual targets using the qla4xxx iSCSI class interface. This patch leaves some dead code, but to make it easier to review we are leaving and in the next patch we will remove that old code. V2 - NOTE: Added code to avoid waiting for AEN during login/logout in the driver, instead added a kernel to user event to notify iscsid about login status. Because of this iscsid will not get blocked. Signed-off-by:
