+Known issues :
+	* Please read the associated RELEASE-NOTES file !!!
+	* This source release intended for upstream kernel releases only!
+
+Changes from 20050323 to 20050413
+
+	* Changed version number to 8.0.28
+	* Fixed build warning for 2.6.12-rc2 kernels: mempool_alloc now
+	  requires a function which takes an unsigned int for gfp_flags.
+	* Removed pci dma sync calls to coherent/consistent pci memory.
+	* Merged patch from Christoph Hellwig <hch@lst.de>: split helpers
+	  for fabric and nport logins out of lpfc_cmpl_els_flogi.
+	* Removed sysfs attributes that are used to dump the various
+	  discovery lists.
+	* Fix for issue where not all luns are seen.  Search all lists
+	  other than unmap list in lpfc_find_target().  Otherwise INQUIRY
+	  to luns on nodes in NPR or other relevant states (PLOGI,
+	  PRLI...) are errored back and scan() terminates.
+	* Removed FC_TRANSPORT_PATCHESxxx defines.  They're in 2.6.12-rc1.
+	* Compare return value of lpfc_scsi_tgt_reset against SCSI
+	  midlayer codes SUCCESS/FAILED which that function returns rather
+	  than SLI return code.
+	* Removed extraneous calls to lpfc_sli_next_iotag which should
+	  only be called from lpfc_sli_submit_iocb.  Also make
+	  lpfc_sli_next_iotag static.
+	* Added PCI ID for LP10000-S.
+	* Changes in lpfc_abort_handler(): Return SUCCESS if we did not
+	  find command in both TX and TX completion queues.  Return ERROR
+	  if we timed out waiting for command to complete after abort was
+	  issued.
+	* Zero-out response sense length in lpfc_scsi_prep_cmnd to prevent
+	  interpretation of stale sense length when the command completes
+	  - was causing spurious 0710 messages.
+	* Moved clearing of host_scribble inside host_lock in IO
+	  completion path.
+	* Fixed a bunch of mixed tab/space indentation.
+	* Allow hex format numbers in sysfs attribute setting.  Fix
+	  application hang when invalid numbers are used in sysfs
+	  settings.
+	* Removed extra iotag allocation by lpfc_abort_handler.
+	* Clear host_scribble in the scsi_cmnd structure when failing in
+	  queuecommand.
+	* Changed logic at top of lpfc_abort_handler so that if the
+	  command's host_scibble field is NULL, return SUCCESS because the
+	  driver has already returned the command to the midlayer.
+
+Changes from 20050308 to 20050323
+
+	* Changed version number to 8.0.27
+	* Changed a few lines from patch submitted by Christoph Hellwig
+	  (3/19). MAILBOX_WSIZE * (uint32_t) is replaced with an
+	  equivalent MAILBOX_CMDSIZE macro.
+	* Merged patch from Christoph Hellwig (3/19): some misc patches
+	  against the latest drivers:
+	  - stop using volatile.  if you need special ordering use memory
+	    barriers but that doesn't seem to be the case here
+	  - switch lpfc_sli_pcimem_bcopy to take void * arguments.
+	  - remove typecast for constants - a U postfix marks them
+	    unsigned int in C
+	  - add a MAILBOX_CMD_SIZE macro, as most users of
+	    MAILBOX_CMD_WSIZE didn't really want the word count
+	  - kill struct lpfc_scsi_dma_buf and embedded the two members
+	    directly in struct lpfc_scsi_buf
+	  - don't call dma_sync function on allocations from
+	    pci_pool_alloc - it's only for streaming mappings (pci_map_*)
+	* Merged patch from Christoph Hellwig (3/19) - nlp_failMask isn't
+	  ever used by the driver, just reported to userspace (and that in
+	  a multi-value file which is against the sysfs guidelines).
+	* Change pci_module_init to pci_register_module() with appropriate
+	  ifdefs.
+	* Added #include <linux/dma-mapping.h> as required by the DMA
+	  32bit and 64bit defines on some archs.
+	* Merged patch from Christoph Hellwig (03/19) - fix initialization
+	  order - scsi_add_host must happen last from scsi POV. Also some
+	  minor style/comment fixups.
+	* Fixed use of TRANSPORT_PATCHES_V2 by changing to
+	  FC_TRANSPORT_PATCHES_V2.
+
+Changes from 20050223 to 20050308
+
+	* Changed version number to 8.0.26
+	* Revise TRANSPORT_PATCHES_V2 so that lpfc_target is removed and
+	  rport data is used instead. Removed device_queue_hash[].
+	* Changed RW attributes of scan_down, max_luns and fcp_bind_method
+	  to R only.
+	* Fixed RSCN handling during initial link initialization.
+	* Fixed issue with receiving PLOGI handling when node is on NPR
+	  list and marked for ADISC.
+	* Fixed RSCN timeout issues.
+	* Reduced severity of "SCSI layer issued abort device" message to
+	  KERN_WARNING.
+	* Feedback from Christoph Hellwig (on 2/5) - In the LPFC_EVT_SCAN
+	  case the caller already has the target ID handly, so pass that
+	  one in evt_arg1.
+	* Fix compile warning/resultant panic in
+	  lpfc_register_remote_port().
+
+Changes from 20050215 to 20050223
+
+	* Changed version number to 8.0.25
+	* Add appropriate comments to lpfc_sli.c.
+	* Use DMA_64BIT_MASK and DMA_32BIT_MASK defines instead of
+	  0xffffffffffffffffULL & 0xffffffffULL respectively.  Use pci
+	  equivalents instead of dma_set_mask and also modify condition
+	  clause to actually exit on error condition.
+	* Restart els timeout handler only if txcmplq_cnt. On submission,
+	  mod_timer the els_tmofunc.  This prevents the worker thread from
+	  waking up the els_tmo handler un-necessarily.  The thread was
+	  being woken up even when there were no pending els commands.
+	* Added new typedefs for abort and reset functions.
+	* Collapsed lpfc_sli_abort_iocb_xxx into a single function.
+	* Collapsed lpfc_sli_sum_iocb_xxx into a single function.
+	* Removed TXQ from all abort and reset handlers since it is never
+	  used.
+	* Fixed Oops panic in 8.0.23 (reported on SourceForge).  The
+	  driver was not handling LPFC_IO_POLL cases correctly in
+	  fast_ring_event and was setting the tgt_reset timeout to 0 in
+	  lpfc_reset_bus_handler.  This 0 timeout would not allow the FW
+	  to timeout ABTS's on bad targets and allow the driver to have an
+	  iocb on two lists.  Also split the lpfc_sli_ringtxcmpl_get
+	  function into two routines to match the fast and slow completion
+	  semantics - ELS completions worked for the wrong reasons.  Also
+	  provided new log message number - had two 0326 entries.
+	* Removed unused #define LPFC_SCSI_INITIAL_BPL_SIZE.
+	* Removed unused struct lpfc_node_farp_pend definition.
+	* Removed unused #define LPFC_SLIM2_PAGE_AREA.
+	* Changed zeros used as pointers to NULL.
+	* Removed unneeded braces around single line in lpfc_do_work.
+	* Close humongous memory leak in lpfc_sli.c - driver was losing 13
+	  iocbq structures per LIP.
+	* Removed last of GFP_ATOMIC allocations.
+	* Locks are not taken outside of nportdisc, hbadisc, els and most
+	  of the init, sli, mbox and ct groups of functions
+	* Fix comment for lpfc_sli_iocb_cmd_type to fit within 80 columns.
+	* Replaced wait_event() with wait_event_interruptible().
+	  wait_event() puts the woker thread in an UNINTERRUPTIBLE state
+	  causing it to figure in load average calculations. Also add a
+	  BUG_ON to the ret code of wait_event_interruptible() since the
+	  premise is that the worker thread is signal-immune.
+
+Changes from 20050208 to 20050215
+
+	* Changed version number to 8.0.24
+	* Fixed a memory leak of iocbq structure.  For ELS solicited iocbs
+	  sli layer now frees the response iocbs after processing it.
+	* Closed large memory leak -- we were losing 13 iocbq structures
+	  per LIP.
+	* Changing EIO and ENOMEM to -EIO and -ENOMEM respectively.
+	* Cleanup of lpfc_sli_iocb_cmd_type array and typing of iocb type.
+	* Implemented Christoph Hellwig's feedback from 02/05: Remove
+	  macros putLunHigh, putLunLow. Use lpfc_put_lun() inline instead.
+	* Integrated Christoph Hellwig's feedback from 02/05: Instead of
+	  cpu_to_be32(), use swab16((uint16_t)lun). This is the same as
+	  "swab16() on LE" and "<<16 on BE".
+	* Added updates for revised FC remote port patch (dev_loss_tmo
+	  moved to rport, hostdata renamed dd_data, add fc_remote_host()
+	  on shutdown).
+	* Removed unnecessary function prototype.
+	* Added code to prevent waking up worker thread after the exit of
+	  worker thread.  Fixes panic seen with insmod/rmmod testing with
+	  70 disks.
+	* Integrated Christoph Hellwig's patch from 1/30: Make some
+	  variables/code static (namely lpfcAlpaArray and
+	  process_nodev_timeout()).
+	* Integrated Christoph Hellwig's patch from 1/30: Use
+	  switch...case instead of if...else if...else if while decoding
+	  JDEC id.
+
+Changes from 20050201 to 20050208
+
+	* Changed version number to 8.0.23
+	* Make lpfc_work_done, lpfc_get_scsi_buf,
+	  lpfc_mbx_process_link_up, lpfc_mbx_issue_link_down and
+	  lpfc_sli_chipset_init static.
+	* Cleaned up references to list_head->next field in the driver.
+	* Replaced lpfc_discq_post_event with lpfc_workq_post_event.
+	* Implmented Christoph Hellwig's review from 2/5: Check for return
+	  values of kmalloc.
+	* Integrated Christoph Hellwig's patch from 1/30: Protecting
+	  scan_tmo and friends in !FC_TRANSPORT_PATCHES_V2 &&
+	  !USE_SCAN_TARGET.
+	* Integrated Christoph Hellwig's patch from 1/30: Some fixes in
+	  the evt handling area.
+	* Integrated Christoph Hellwig's patch from 1/30: Remove usage of
+	  intr_inited variable. The interrupt initilization from OS side
+	  now happens in lpfc_probe_one().
+	* Integrated Christoph Hellwig's patch from 1/30: remove shim
+	  lpfc_alloc_transport_attr - remove shim lpfc_alloc_shost_attrs -
+	  remove shim lpfc_scsi_host_init - allocate phba mem in scsi's
+	  hostdata readjust code so that they are no use after free's
+	  (don't use after scsi_host_put) - make lpfc_alloc_sysfs_attr
+	  return errors
+	* Fixed panic in lpfc_probe_one(). Do not delete in a list
+	  iterator that is not safe.
+	* Clean up fast lookup array of the fcp_ring when aborting iocbs.
+	* Following timeout handlers moved to the lpfc worker thread:
+	  lpfc_disc_timeout, lpfc_els_timeout, lpfc_mbox, lpfc_fdmi_tmo,
+	  lpfc_nodev_timeout, lpfc_els_retry_delay.
+	* Removed unused NLP_NS_NODE #define.
+	* Integrated Christoph Hellwig's patch from 1/30: remove unused
+	  lpfc_hba_list; remove unused lpfc_rdrev_wd30; remove
+	  lpfc_get_brd_no and use Linux provided IDR.
+	* Changed board reset procedure so that lpfc_sli_send_reset()
+	  writes the INITFF bit and leaves lpfc_sli_brdreset() to clear
+	  the bit.
+	* Removed outfcpio sysfs device attribute.
+	* VPD changes: 1) Modify driver to use the model name and
+	  description from the VPD data if it exists 2) Rework use of DUMP
+	  mailbox command to support HBAs with 256 bytes of SLIM.
+	* Fixed compile error for implicit definition of struct
+	  scsi_target
+
+Changes from 20050124 to 20050201
+
+	* Changed version number to 8.0.22
+	* Moved discovery timeout handler to worker thread. There are
+	  function calls in this function which are not safe to call from
+	  HW interrupt context.
+	* Removed free_irq from the error path of HBA initialization.
+	  This will fix the free of uninitialised IRQ when config_port
+	  fails.
+	* Make sure function which processes unsolicited IOCBs on ELS ring
+	  still is called with the lock held.
+	* Clear LA bit from work_ha when we are not supposed to handle LA.
+	* Fix double locking bug in the error handling part of
+	  lpfc_mbx_cmpl_read_la.
+	* Implemented fast IOCB processing for FCP ring.
+	* Since mboxes are now unconditionally allocated outside of the
+	  lock, free them in cases where they are not used.
+	* Moved out a couple of GFP_ATOMICs in lpfc_disc_timeout, to
+	  before locks so that they can GFP_KERNEL instead. Also cleaned
+	  up code.
+	* Collapsed interrupt handling code into one function.
+	* Removed event posting and handling of solicited and unsolicited
+	  iocbs.
+	* Remove ELS ring handling leftovers from the lpfc_sli_inter().
+	* ELS ring (any slow ring) moved from the lpfc_sli_inter() into a
+	  worker thread.  Link Attention, Mbox Attention, and Error
+	  Attention, as well as slow rings' attention is passed to the
+	  worker thread via worker thread copy of Host Attention
+	  register. Corresponding events are removed from the event queue
+	  handling.
+	* Add entries to hba structure to delegate some functionality from
+	  the lpfc_sli_inter() to a worker thread.
+	* Reduced used of GFP_ATOMIC for memory allocations.
+	* Moved locks deeper in order to change GFP_ATOMIC to GFP_KERNEL.
+	* IOCB initialization fix for Raw IO.
+	* Removed qcmdcnt, iodonecnt, errcnt from lpfc_target and from
+	  driver.
+	* Added call to lpfc_els_abort in lpfc_free_node.  Modified
+	  lpfc_els_abort to reset txq and txcmplq iterator after a
+	  iocb_cmpl call.
+	* Fixed a use after free issue in lpfc_init.c.
+	* Defined default mailbox completion routine and removed code in
+	  the sli layer which checks the mbox_cmpl == 0 to free mail box
+	  resources.
+	* In lpfc_workq_post_event, clean up comment formatting and remove
+	  unneeded cast of kmalloc's return.
+	* Removed loop which calls fc_remote_port_unblock and
+	  fc_remote_port_delete for every target as this same effect is
+	  accomplished by the scsi_remove_host call.
+	* Minor cleanup of header files.  Stop header files including
+	  other header files.  Removed sentinels which hide multiple
+	  inclusions.  Removed unneeded #include directives.
+	* Fixed memory leaks in mailbox error paths.
+	* Moved lock from around of lpfc_work_done to lpfc_work_done
+	  itself.
+	* Removed typedef for LPFC_WORK_EVT_t and left just struct
+	  lpfc_work_evt to comply with linux_scsi review coding style.
+	* Fixed some trailing whitespaces, spaces used for indentation and
+	  ill-formatting multiline comments.
+	* Bug fix for Raw IO errors.  Reuse of IOCBs now mandates setting
+	  of ulpPU and fcpi_parm to avoid incorrect read check of Write IO
+	  and incorrect read length.
+
+Changes from 20050110 to 20050124
+
+	* Changed version number to 8.0.21
+	* Removed unpleasant casting in the definition and use of
+	  lpfc_disc_action function pointer array.
+	* Makefile cleanup.  Use ?= operator for setting default
+	  KERNELVERSION and BASEINCLUDE values.  Use $(PWD) consistently.
+	* Removed call to lpfc_sli_intr from lpfc_config_port_post.  All
+	  Linux systems will service hardware interrupts while bringing up
+	  the driver.
+	* Christoph Hellwig change request: Reorg of contents of
+	  lpfc_hbadisc.c, lpfc_scsi.h, lpfc_init.c, lpfc_sli.c,
+	  lpfc_attr.c, lpfc_scsi.c.
+	* Renamed discovery thread to lpfc_worker thread.  Moved handling
+	  of error attention and link attention and mbox event handler to
+	  lpfc_worker thread.
+	* Removed .proc_info and .proc_name from the driver template and
+	  associated code.
+	* Removed check of FC_UNLOADING flag in lpfc_queuecommand to
+	  determine what result to return.
+	* Move modification of FC_UNLOADING flag under host_lock.
+	* Fix IOERR_RCV_BUFFER_WAITING handling for CT and ELS subsystem.
+	* Workaround firmware bug for IOERR_RCV_BUFFER_WAITING on ELS
+	  ring.
+	* Fixed a couple lpfc_post_buffer problems in lpfc_init.c.
+	* Add missing spaces to the parameter descriptions for
+	  lpfc_cr_delay, lpfc_cr_count and lpfc_discovery_threads.
+	* Lock before calling lpfc_sli_hba_down().
+	* Fix leak of "host" in the error path in the remove_one() path.
+	* Fix comment for lpfc_cr_count.  It defaults to 1.
+	* Fix issue where we are calling lpfc_disc_done() recursively from
+	  lpfc_linkdown(), but list_for_each_entry_safe() is not safe for
+	  such use.
+	* Bump lpfc_discovery_threads (count of outstading ELS commands in
+	  discovery) to 32
+	* If the SCSI midlayer tries to recover from an error on a lun
+	  while the corresponding target is in the NPR state, lpfc driver
+	  will reject all the resets. This will cause the target to be
+	  moved to offline state and block all the I/Os. The fix for this
+	  is to delay the lun reset to a target which is not in MAPPED
+	  state until the target is rediscovered or nodev timeout is
+	  fired.
+
+Changes from 20041229 to 20050110
+
+	* Changed version number to 8.0.20
+	* rport fix: use new fc_remote_port_rolechg() function instead of
+	  direct structure change
+	* rport fix: last null pointer check
+	* Phase II of GFP_ATOMIC effort.  Replaced iocb_mem_pool and
+	  scsibuf_mem_pool with kmalloc and linked list.  Inserted list
+	  operations for mempool_alloc calls.  General code cleanup.  All
+	  abort and reset routines converted.  Handle_ring_event
+	  converted.
+	* If the mbox_cmpl == lpfc_sli_wake_mbox_wait in
+	  lpfc_sli_handle_mb_event, pmb->context1 points to a waitq. Do
+	  not free the structure.
+	* rport fixes: fix for rmmod crash
+	* rport fixes: when receiving PRLI's, set node/rport role values
+	* rport fixes: fix for unload and for fabric port deletes
+	* VPD info bug fix.
+	* lpfc_linkdown() should be able to process all outstanding events
+	  by calling lpfc_disc_done() even if it is called from
+	  lpfc_disc_done() Moving all events from phba->dpc_disc to local
+	  local_dpc_disc prevents those events from being processed.
+	  Removing that queue. From now on we should not see "Illegal
+	  State Transition" messages.
+	* Release host lock and enable interrupts when calling
+	  del_timer_sync()
+	* All related to rports: Clean up issues with rport deletion
+	  Convert to using block/unblock on list remove (was del/add)
+	  Moved rport delete to freenode - so rport tracks node.
+	* rport fixes: for fport, get maxframe and class support
+	  information
+	* Added use of wait_event to work with kthread interface.
+	* Ensure that scsi_transport_fc.h is always pulled in by
+	  lpfc_scsiport.c
+	* In remote port changes: no longer nulling target->pnode when
+	  removing from mapped list. Pnode get nulled when the node is
+	  freed (after nodev tmo). This bug was causing i/o recieved in
+	  the small window while the device was blocked to be errored w/
+	  did_no_connect. With the fix, it returns host_busy
+	  (per the pre-remote port changes).
+	* Merge in support for fc transport remote port use. This removes
+	  any consistent bindings within the driver. All scanning is now
+	  on a per-target basis driven by the discovery engine.
+
+Changes from 20041220 to 20041229
+
+	* Changed version number to 8.0.19
+	* Fixed bug for handling RSCN type 3.  Terminate RSCN mode
+	  properly after ADISC handling completes.
+	* Add list_remove_head macro.  Macro cleans up memory allocation
+	  list handling.  Also clean up lpfc_reset_bus_handler - routine
+	  does not need to allocate its own scsi_cmnd and scsi_device
+	  structures.
+	* Fixed potential discovery bug, nlp list corrutpion fix potential
+	  memory leak
+	* Part 1 of the memory allocation rework request by linux-scsi.
+	  This effort fixes the number of bdes per scsi_buf to 64, makes
+	  the scatter-gather count a module parameter, builds a linked
+	  list of scsi_bufs, and removes all dependencies on lpfc_mem.h.
+	* Reverted lpfc_do_dpc, probe_one, remove_one to original
+	  implementation.  Too many problems (driver not completing
+	  initial discovery, and IO not starting to disks).  Backs out
+	  kthread patch.
+	* Fix race condition in lpfc_do_dpc.  If wake_up interrupt occurs
+	  while lpfc_do_dpc is running disc_done and the dpc list is
+	  empty, the latest insertion is missed and the schedule_timeout
+	  does not wakeup.  The sleep interval is MAX_SCHEDULE_TIMEOUT
+	  defined as ~0UL >> 1, a very large number.  Hacked it to 5*HZ
+	  for now.
+	* Fixed bug introduced when discovery thread implementation was
+	  moved to kthread. kthread_stop() is not able to wake up thread
+	  waiting on a semaphore and "modprobe -r lpfc" is not always
+	  (most of the times) able to complete. Fix is in not using
+	  semaphore for the interruptable sleep.
+	* Small Makefile cleanup - Remove remnants of 2.4 vs. 2.6
+	  determination.
+
+Changes from 20041213 to 20041220
+
+	* Changed version number to 8.0.18
+	* Janitorial cleanup after removal of sliinit and ringinit[] ring
+	  statistic is owned by the ring and SLI stats are in sli
+	  structure.
+	* Integrated patch from Christoph Hellwig <hch@lst.de> Kill
+	  compile warnings on 64 bit platforms: %variables for %llx format
+	  specifiers must be caste to long long because %(u)int64_t can
+	  just be long on 64bit platforms.
+	* Integrated patch from Christoph Hellwig <hch@lst.de> Removes
+	  dead code.
+	* Integrated patch from Christoph Hellwig <hch@lst.de>: use
+	  kthread interface.
+	* Print LPFC_MODULE_DESC banner in module init routine.
+	* Removed sliinit structure and ringinit[] array.
+	* Changed log message number from 324 to 326 in lpfc_sli.c.
+	* Wait longer for commands to complete in lpfc_reset_bus_handler
+	  and lpfc_reset_bus_handler.  Also use schedule_timeout() instead
+	  of msleep() and add error message in lpfc_abort_handler()
+	* When setting lpfc_nodev_tmo, from dev_loss set routine, make 1
+	  sec minimum value.
+	* Functions which assume lock being held were called without lock
+	  and kernel complained about unlocking lock which is not locked.
+	* Added code in linkdown to unreg if we know login session will be
+	  terminated.
+	* Removed automap config parameter and fixed up use_adisc logic to
+	  include FCP2 devices.
+
+Changes from 20041207 to 20041213
+
+	* Changed version number to 8.0.17
+	* Fix sparse warnings by adding __iomem markers to lpfc_compat.h.
+	* Fix some sparse warnings -- 0 used as NULL pointer.
+	* Make sure there's a space between every if and it's (.
+	* Fix some overly long lines and make sure hard tabs are used for
+	  indentation.
+	* Remove all trailing whitespace.
+	* Integrate Christoph Hellwig's patch for 8.0.14: if
+	  pci_module_init fails we need to release the transport template.
+ 	  (also don't print the driver name at startup, linux drivers can
+	  be loaded without hardware present, and noise in the log for
+	  that case is considered unpolite, better print messages only for
+	  hardware actually found).
+	* Integrate Christoph Hellwig's patch for 8.0.14: Add missing
+	  __iomem annotations, remove broken casts, mark functions static.
+	  Only major changes is chaning of some offsets from word-based to
+	  byte-based so we cans simply do void pointer arithmetics (gcc
+	  extension) instead of casting to uint32_t.
+	* Integrate Christoph Hellwig's patch for 8.0.14: flag is always
+	  LPFC_SLI_ABORT_IMED, aka 0 - remove dead code.
+	* Modified preprocessor #ifdef, #if, #ifndef to reflect upstream
+	  kernel submission.  Clean build with make clean;make and make
+	  clean;make ADVANCED=1 on SMP x86, 2.6.10-rc2 on RHEL 4 Beta
+	  1. IO with a few lips and a long cable pull behaved accordingly.
+	* Implement full VPD support.
+	* Abort handler will try to wait for abort completion before
+	  returning.  Fixes some panics in iocb completion code path.
+
+Changes from 20041130 to 20041207
+	
+	* Changed version number to 8.0.16
+	* Hung dt session fix.  When the midlayer calls to abort a scsi
+	  command, make sure the driver does not complete post-abort
+	  handler.  Just NULL the iocb_cmpl callback handler and let SLI
+	  take over.
+	* Add Read check that uses SLI option to validate all READ data
+	  actually received.

+
+Changes from 20041123 to 20041130
+
+	* Changed version number to 8.0.15
+	* Ifdef'd unused "binary" attributes by DFC_DEBUG for clean
+	  compiles
+	* Stop DID_ERROR from showing up along with QUEUE_FULL set by the
+	  Clarion array (SCSI error ret. val.  0x70028) There is no need
+	  for driver to hard fail command which was failed by the target
+	  device.
+	* Fix for Scsi device scan bug reported on SourceForge.  Driver
+	  was returning a DID_ERROR in lpfc_handle_fcp_error causing
+	  midlayer to mark report luns as failing even though it
+	  succeeded.
+	* Don't ignore SCSI status on underrun conditions for inquiries,
+	  test unit ready's, etc.  This was causing us to lose
+	  reservation conflicts, etc
+
+Changes from 20041018 to 20041123
+	
+	* Changed version number to 8.0.14
+	* Added new function "iterator" lpfc_sli_next_iocb_slot() which
+	  returns pointer to iocb entry at cmdidx if queue is not full.
+	  It also updates next_cmdidx, and local_getidx (but not cmdidx)
+	* lpfc_sli_submit_iocb() copies next_cmdidx into cmdidx. Now it is
+	  the only place were we are updating cmdidx.
+	* lpfc_sli_update_ring() is split in to two --
+	  lpfc_sli_update_ring() and lpfc_sli_update_full_ring().
+	* lpfc_sli_update_ring() don't to read back correct value of
+	  cmdidx.
+	* Simplified lpfc_sli_resume_iocb() and its use.
+	* New static function lpfc_sli_next_iocb(phba, pring, &piocb) to
+	  iterate through commands in the TX queue and new command (at the
+	  end).
+	* Reduced max_lun to 256 (due to issues reported to some arrays).
+	  Fixed comment, and macro values so def=256, min=1, max=32768.
+	* Fix an obvious typo/bug: kfree was used to free lpfc_scsi_buf
+	  instead of mempool_free in lpfc_scsiport.c.
+	* Suppress nodev_tmo message for FABRIC nodes.
+	* Fixed some usage of plain integer as NULL pointer.
+	* Bug fix for FLOGI cmpl, lpfc_els_chk_latt error path code
+	  cleanup.
+	* Fixup lpfc_els_chk_latt() to have Fabric NPorts go thru
+	  discovery state machine as well.
+	* Fixes to lpfc_els_chk_latt().
+	* Use DID not SCSI target id as a port_id and add some missing
+	  locks in lpfc_fcp.c.
+	* Changed eh_abort_handler to return FAILED if command is not
+	  found in driver.
+	* Fix crash: paging request at virtual address 0000000000100108 -
+	  a result of removing from the txcmpl list item which was already
+	  removed (100100 is a LIST_POISON1 value from the next pointer
+	  and 8 is an offset of the "prev") Driver runs out of iotags and
+	  does not handle that case well. The root of the proble is in the
+	  initialization code in lpfc_sli.c
+	* Changes to work with proposed linux kernel patch to support
+	  hotplug.
+	* Zero out seg_cnt in prep_io failure path to prevent double sg
+	  unmap calls.
+	* Fix setting of upper 32 bits for Host Group Ring Pointers if in
+	  SLIM. Old code was inappropriately masking off low order bits.
+	* Use scsi_[activate|deactivate]_tcq calls provided in scsi_tcq.h.
+	* Integrated patch from Christoph Hellwig (hch@lst.de): don't call
+	  pci_dma_sync_* on coherent memory. pci_dma_sync_* is need and
+	  must be used only with streaming dma mappings pci_map_*, not
+	  coherent mappings.  Note: There are more consistent mappings
+	  that are using pci_dma_sync calls. Probably these should be
+	  removed as well.
+	* Modified lpfc_free_scsi_buf to accomodate all three scsi_buf
+	  free types to alleviate miscellaneous panics with cable pull
+	  testing.
+	* Set hotplug to default 0 and lpfc_target_remove to not remove
+	  devices unless hotplug is enabled.
+	* Fixed discovery bug: plogi cmpl uses ndlp after its freed.
+	* Fixed discovery bug: rnid acc cmpl, can potentially use ndlp
+	  after its freed.
+	* Modularize code path in lpfc_target_remove().
+	* Changes to support SCSI hotplug (ifdef'ed out because they need
+	  kernel support USE_SCAN_TARGET requires kernel support to export
+	  the interface to scsi_scan_target and to move the SCAN_WILD_CARD
+	  define to a general scsi header file.  USE_RESCAN_HOST requires
+	  kernel support to export an interface to scan_scsi_host() with
+	  the rescan flag turned on).
+	* Removed redundant variable declaration of lpfc_linkdown_tmo.
+	* Fix for large port count remove test.
+	* Added check to see if BAR1 register is valid before using BAR1
+	  register for programming config_port mail box command.
+	* Added lpfc_scsi_hotplug to enable/disable driver support of SCSI
+	  hotplug.
+	* Changed lpfc_disc_neverdev() to lpfc_disc_illegal() and changed
+	  lpfc_disc_nodev() to lpfc_disc_noop().  Adjusted appropriate
+	  events to use these routines.
+	* Add support for SCSI device hotplug.
+	* Take dummy lpfc_target's into account for lpfc_slave_destroy().
+	* Bug fix to store WWPN / WWNN in NameServer / FDMI lpfc_nodelist
+	  entries.
+	* Added slavecnt in lpfc_target for diagnostic purposes.
+	* Added lpfc_hba load/unload flags to take care of special cases
+	  for add/remove device.
+	* Have target add/remove delay before scanning.
+	* Have rmmod path cleanup blocked devices before scsi_remove_host.
+	* Added a #define for msleep for 2.6.5 kernels.
+	* In reset bus handler if memory allocation fails, return FAILED
+	  and not SUCCESS.
+	* Have lpfc eh handlers, bus_reset and lun_reset, wait for all
+	  associated I/Os to complete before returning.
+	* Fix memset byte count in lpfc_hba_init so that
+	  LP1050 would initialize correctly.
+	* Backround nodev_timeout processing to DPC This enables us to
+	  unblock (stop dev_loss_tmo) when appopriate.
+	* Fix array discovery with multiple luns.  The max_luns was 0 at
+	  the time the host structure was intialized.  lpfc_cfg_params
+	  then set the max_luns to the correct value afterwards.
+	* Remove unused define LPFC_MAX_LUN and set the default value of
+	  lpfc_max_lun parameter to 512.
+	* Reduced stack usage of lpfc_hba_init.
+	* Cleaned up the following warning generated by
+	  scripts/checkincludes.pl lpfc_fcp.c: scsi/scsi_cmnd.h is
+	  included more than once.
+	* Replaced "set_current_state(TASK_UNINTERRUPTIBLE);
+	  schedule_timeout(timeout)" with "msleep(timeout)".
+	* Fixnode was loosing starget when rediscovered. We saw messages
+	  like: lpfc 0000:04:02.0: 0:0263 Cannot block scsi target as a
+	  result.  Moved starget field into struct lpfc_target which is
+	  referenced from the node.
+	* Add additional SLI layer logging in lpfc_sli.c.
+	* Ignore more unexpected completions in lpfc_nportdisc.c.
+	* Can not call lpfc_target_unblock from the soft interrupt
+	  context.  It seems to be not nessasery to unblock target from
+	  nodev timeout.
+	* Introduce and use less lethal event handler for unexpected
+	  events in lpfc_nportdisc.c.
+	* Can not call fc_target_(un)block() functions with interrupts
+	  disabled in lpfc_scsiport.c.
+	* Added new configuration parameter, lpfc_max_luns range 1-32768,
+	  default 32768.
+	* Allow lpfc_fcp.c to call lpfc_get_hba_sym_node_name().
+	* Increase nodev timeout from 20 seconds to 30 seconds.
+	* Replace some kfree((void*)ptr) with kfree(ptr).
+	* Make 3 functions static: lpfc_get_hba_sym_node_name,
+	  lpfc_intr_prep and lpfc_setup_slim_access.  Move lpfc_intr_prep
+	  and lpfc_setup_slim_access so they're defined before being used.
+	* Remove an unecessary list_del() in lpfc_hbadisc.c.
+	* Set nlp_state before calling lpfc_nlp_list() since this will
+	  potentially call fc_target_unblock which may cause a race in
+	  queuecommand by releasing host_lock.
+	* Since lpfc_nodev_tmo < dev_loss_tmo remove queuecommand
+	  DID_BAD_TARGET return for now.
+	* Fix a problem with rcv logo.
+	* Remove unused portstatistics_t structure.
+	* Remove #if 0 and unnecessary checks in lpfc_fcp.c.
+	* Simplify lpfc_issue_lip: Extra layer of protection removed.
+	* Grab lock before calling lpfc_sli_issue_mbox(phba, pmb,
+	  MBX_NOWAIT) in lpfc_sli_issue_mbox_wait().
+
+Changes from 20040920 to 20041018
+
+	* Changed version number to 8.0.13
+	* Hide some attributes using #ifndef DFC_DEBUG ... #endif.
+	* Modify Makefile to (1) make BUILD_NO_DEBUG=1 will hide some
+	  (binary) attributes (2) make BUILD_FC_TRANS=0 will build driver
+	  for 2.6.5 kernel with block/unblock patch.
+	* Modified #ifdef names.
+	* Added support for proposed FC transport host attributes (which
+	  replaces some of the attributes we had local to the driver).
+	  Removed the binary statistics sysfs attribute.
+	* Added extra ELS verbose logging for ELS responses.
+	* Added recognition for BUILD_FC_TRANS=2 to Makefile to define
+	  FC_TRANS_VER2.
+	* Add a pointer for link stats allocation.
+	* Exported lpfc_get_hba_sym_node_name for use by FC_TRANS_VER2
+	  sysfs routines.
+	* Fix discovery problem in lip testing: if device sends an ELS cmd
+	  (i.e. LOGO) before our FLOGI completes it should be LS_RJT'ed.
+	* Moved #defines around to provide target_add/remove for upstream
+	  kernel deliverables only not SLES9.  Provided ifdefs to #include
+	  target_block/unblock only if FC_TRANS_VER1.
+	* Add sanity check in lpfc_nlp_list move setting nlp_Target
+	  outside #ifdef.
+	* Added a blocked member to the lpfc_target structure for
+	  block/unblock.  This member allows the driver to know when to
+	  unblock for pci_remove_one or pci_add_one.  #ifdef'd some more
+	  block/unblock stuff and removed some defensive checks from
+	  target_block/unblock.
+	* Moved + 5 second window to dev_loss_tmo setting and updated
+	  comments.
+	* Removed NULL target check from target_block/unblock and fixed up
+	  a few comments.
+	* Enable sysfs attributes on 2.6.5 kernels and remove extra
+	  compatibility code.
+	* Remove any and all trailing whitespace.
+	* Added message 0718 and return error when dma_map_single fails.
+	* Changed the fcpCntl2 commands to include an FCP_ prefix to get
+	  rid of build warnings on later 2.6.9-rc kernels.  Build
+	  conflicts with scsi/scsi.h.  Remove inclusions of scsi/scsi.h
+	  from hbadisc.c, sli.c, and fcp.c since these modules had no
+	  dependencies on scsi.h.
+	* Fixed a bug with RSCN handling. A RSCN received on one device,
+	  shouldn't affect other devices not referenced by the RSCN.
+	* Moved #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,6) to include
+	  lpfc_jedec_to_ascii to prevent warning in SLES 9.
+	* Update Makefile to account for SLES 9 and scsi-target upstream
+	  kernel.
+	* This checkin provides block/unblock hooks for the upstream scsi
+	  target kernel and 2.6.5 on SLES9 SP1 with the block/unblock
+	  patch.
+	* Discovery changes regarding setting targetp->pnode and
+	  ndlp->nlp_Target Ensure fc_target_* routines are called properly
+	  from discovery.  Remove list_del's from lpfc_cleanup().  Ensure
+	  all the lpfc_consistent_bind_* routines don't set any driver
+	  structure objects.
+	* Fix for timeout of READ_LA or READ_SPARAM mailbox command
+	  causing panic.
+	* Cleanup list_del()'s for Discovery ndlp lists.
+	* Bug fixes for some insmod/rmmod crashes, link down crashes and
+	  device loss crashes.
+	* Removed NLP_SEARCH_DEQUE.
+	* Call lpfc_target_unblock only if the targetp is nonNull and with
+	  the host_lock held.
+	* Added qcmdcnt back along with misc bug fixes to discovery.
+	* Changed tgt_io to outfcpio lpfc_fcp.c.
+	* Fixed errors caused by LIP and cable pulls both with and without
+	  block/unblock patch.
+	* For now we have to call fc_target_unblock and fc_target_block
+	  with interrupts enabled.
+	* Save seg_cnt from dma_map_sg.  Save scatter-gather start address
+	  and pass back to dma_unmap_sg in error with seg_cnt.
+	* Incorporating block/unblock calls into driver with ifdefs.  This
+	  change is supported by scsi-target-2.6 kernel and forward only.
+	* Merged in some discovery bug fixes and added tgt io counters.
+	* Added sysfs attributes/interfaces: read only attribute
+	  "management_version" and write only attribute "issue_lip".
+	* Fix build on big endian machines: while #if was OK with
+	  __BIG_ENDIAN which defined as 4321, __BIG_ENDIAN_BITFIELD has to
+	  be tested with #ifdef because it does not have any value, it is
+	  either defined or not.
+	* Add fabric_name and port_type attributes.
+	* Change mdelay to msleep.  mdelay works, but wastefully uses cpu
+	  resources without a lock held. Revert to msleep.  Tested with
+	  sg_reset for bus and three attached targets.
+	* Added the customary #ifndef...#define...#endif to
+	  lpfc_version.h.
+	* Integrate patches from Christoph Hellwig: two new helpers common
+	  to lpfc_sli_resume_iocb and lpfc_sli_issue_iocb - singificant
+	  cleanup of those two functions - the unused SLI_IOCB_USE_TXQ is
+	  gone - lpfc_sli_issue_iocb_wait loses it's flags argument
+	  totally.
+	* Fix in lpfc_sli.c: we can not store a 5 bit value in a 4-bit
+	  field.
+	* Moved some routines out of lpfc_fcp.c into more appropriate
+	  files.
+	* Whitespace cleanup: remove all trailing whitespace.
+	* Make lpfc_disc_ndlp_show static to lpfc_fcp.c.
+	* Remove leftover printk and replace some with
+	  printk(KERN_WARNING)
+	* Trivial: fix a few long lines and a soft tab.
+	* Remove warnings generated by Sparse against driver (make
+	  C=1). Mostly these are "using integer as pointer warnings"
+	  i.e. use NULL instead of 0.
+	* Integrated patch from Christoph Hellwig: Quite a lot of changes
+	  here, the most notable is that the phba->slim2p lpfc_dmabuf goes
+	  away in favour of a typede pointer and a dma_addr_t.  Due to the
+	  typed pointer lots of the cast mess can go away, and while at it
+	  I also replaced the messy SLI2_SLIM_t with a simple struct
+	  lpfc2_sli2_slim that only contains the part of the union we care
+	  about while using SLI2_SLIM_SIZE for all size calculations
+	  directly.
+	* Integrated patch from Christoph Hellwig: This streamlines the
+	  I/O completion path a little more, especially taking care of
+	  fast-pathing the non-error case.  Also removes tons of dead
+	  members and defines from lpfc_scsi.h - e.g. lpfc_target is down
+	  to nothing more then the lpfc_nodelist pointer.
+	* Added binary sysfs file to issue mbox commands
+	* Replaced #if __BIG_ENDIAN with #if __BIG_ENDIAN_BITFIELD for
+	  compatibility with the user space applications.
+	* Decrease the amount of data in proc_info.
+	* Condense nodelist flag members.
+	* Expand INFO for discovery sysfs shost entries.
+	* Notify user if information exceeds 4k sysfs limit.
+	* Removed a bunch of unused #defines.
+	* Added initial sysfs discovery shost attributes.
+	* Remove unused #defines lpfc_disc.h.
+	* Fixed failMask nodelist settings.
+	* Cleanup some old comments / unused variables.
+	* Add LP101 to list of recognized adapters.
+
+Changes from 20040908 to 20040920
+
+	* Changed version number to 8.0.12
+	* Removed used #defines: DEFAULT_PCI_LATENCY_CLOCKS and
+	  PCI_LATENCY_VALUE from lpfc_hw.h.
+	* Changes to accomodate rnid.
+	* Fix RSCN handling so RSCN NS queries only effect NPorts found in
+	  RSCN data.
+	* If we rcv a plogi on a NPort queued up for discovery, clear the
+	  NLP_NPR_2B_DISC bit since rcv plogi logic will force NPort thru
+	  discovery.
+	* Ensure lpfc_target is also cleaned up in lpfc_cleanup().
+	* Preliminary changes for block/unblock kernel API extensions in
+	  progress with linux-scsi list.  These are name changes and
+	  prototype changes only.
+	* Added send_abts flag to lpfc_els_abort. For rcv LOGO when ADISC
+	  sent, the XRI of the LOGO rcv'ed is the same as the ADISC
+	  sent. Thus we cannot ABTS the ADISC before sending the LOGO ACC.
+	* Weed out some unused fc_flags.  Add FC_DISC_TMO.
+	* board_online sysfs attribute added to support libdfc functions
+	  InitDiagEnv and SetBrdEnv.
+	* Streamline code in lpfc_els_retry fixup abort case in
+	  lpfc_els_timeout_handler().
+	* Flush discovery/ELS events when we bring SLI layer down.
+	* ctlreg and slimem binary attributes added to support libdfc
+	  read/write mem/ctl functions.
+	* Integrated Christoph Hellwig's patch: Cleanup
+	  lpfc_sli_ringpostbuf_get.
+	* Modified lpfc_slave_alloc and lpfc_slave_destroy to allocate and
+	  free a dummy target pointer.  This allows queuecommand to skip
+	  the NULL target pointer check and avoid the console spam when
+	  slave_alloc fails.
+	* Fix cfg_scan_down logic, it was reversed.
+	* Init list head ctrspbuflist.
+	* Change name of lpfc_driver_abort to lpfc_els_abort since it is
+	  only valid for ELS ring.
+	* Remove unused third argument for lpfc_consistent_bind_get().
+	* Fix up iotag fields in lpfc_prep_els_iocb().
+	* Remove log message on code path triggered by lpfc_els_abort().
+	* Set host->unique_id in lpfc_fcp.c.
+	* Removed deadwood: lpfc_target.pHba not necessary anymore.
+	* Integrated patch from Christoph Hellwig: remove dead
+	  SLI_IOCB_POLL handling.
+	* Integrated patch from Christoph Hellwig: Streamline I/O
+	  submission and completion path a little.
+	* Remove unnecessary lpfc_brd_no.  Ensure brd_no assignment is
+	  unique.
+	* Removed unused MAX_FCP_LUN.
+	* Use mod_timer instead of add_timer for fdmi in lpfc_ct.c.
+	* Fixed misc discovery problems.
+	* Move stopping timers till just before lpfc_mem_free() call.
+	* Fix up NameServer reglogin error path.
+	* Cleanup possible outstanding discovery timers on rmmod.
+	* Fix discovery NPort to NPort pt2pt problem.
+	* Get rid of ip_tmofunc / scsi_tmofunc.
+	* Integrated patch from Christoph Hellwig:
+	  lpfc_disc_done/lpfc_do_dpc cleanup - lpfc_disc_done can return
+	  void - move lpfc_do_dpc and lpfc_disc_done to lpfc_hbadisc.c -
+	  remove checking of list emptiness before calling lpfc_disc_done,
+	  it handles the emtpy list case just fine and the additional
+	  instructions cost less then the bustlocked spinlock operations.
+	* Integrated patch from Christoph Hellwig: This adds a new 64bit
+	  counter instead, brd_no isn't reused anymore.  Also some tiny
+	  whitespace cleanups in surrounding code.
+	* Reorder functions in lpfc_els.c to remove need for prototypes.
+	* Removed unsed prototypes from lpfc_crtn.h -
+	  lpfc_ip_timeout_handler, lpfc_read_pci and lpfc_revoke.
+	* Removed some unused prototypes from lpfc_crtn.h -
+	  lpfc_scsi_hba_reset, lpfc_scsi_issue_inqsn,
+	  lpfc_scsi_issue_inqp0, lpfc_scsi_timeout_handler.
+	* Integrated patch from Christoph Hellwig: remove TRUE/FALSE
+	  usage.
+	* Integrated patch from Christoph Hellwig: Remove unused function
+	  prototypes lpfc_set_pkt_len and lpfc_get_pkt_data from
+	  lpfc_crtn.h - fixes build warnings.
+	* Removed unused struct lpfc_dmabufip definition from lpfc_mem.h.
+	* Removed pre-2.6.5 MODULE_VERSION macro from lpfc_compat.h.
+	* Fixing missing static and removing dead code.
+	* Adding nodewwn, portwwn and portfcid shost attributes.
+	* Initial support for CT via sysfs. request payloads of size less
+	  than PAGE_SIZE and rsp payloads of size PAGE_SIZE are supported.
+	  Driver maintains a list of rsp's and passes back rsp's
+	  corresponding to the pid of the calling process.
+	* Support for RefreshInformation, GetAdapterAttributes,
+	  GetPortStatistics.
+	* Make nodev-tmo default to 20 seconds.
+	* Fix up some DSM error cases, unreg_login rpi where needed.
+	* Fix up comments for fc_target_block / fc_target_unblock.
+	* Fix up code for scsi_block_requests / scsi_unblock_requests.
+	* Add NLP_FCP_TARGET for nodeinfo support.
+	* Move suspend/resume in lpfc_nlp_list under appropriate case -
+	  Used host_lock for DPC to avoid race (remove dpc_lock)
+	* Fix some corner cases for PLOGI receive - simplify error case
+	  for cmpl_reglogin_reglogin_issue.
+	* Bug fix for ppc64 EEH MMIO panic - always do readl after
+	  writel's of HBA registers to force flush.
+	* Get rid of initial static routine declarations in lpfc_hbadisc.c
+	  and lpfc_els.c.
+	* Updates to discovery processing.
+
+Changes from 20040823 to 20040908
+
+	* Changed version number to 8.0.11
+	* Removed persistent binding code.
+	* Display both ASC and ASCQ info.
+	* Fixed link down->up transitions when linkdown tmo expires. Fix
+	  was in the defensive error checking at the start of
+	  queuecommand.
+	* Removed lpfc_scsi_timeout_handler as this timer is no longer
+	  required.  The midlayer will exhaust retries and then call
+	  lpfc_abort_handler, lpfc_reset_lun_handler, and
+	  lpfc_reset_target_handler.
+	* Minimal support for SCSI flat space addressing/volume set
+	  addressing.  Use 16 bits of LUN address so that flat
+	  addressing/VSA will work.
+	* Changed 2 occurences of if( 1 != f(x)) to if(f(x) != 1)
+	* Drop include of lpfc_cfgparm.h.
+	* Reduce stack usage of lpfc_fdmi_cmd in lpfc_ct.c.
+	* Add minimum range checking property to /sys write/store
+	  functions.
+	* Fix display of node_name and port_name via fc transport
+	  attr.
+	* Removed biosparam code.
+	* Removed range checking. phba->config[] array elements are now
+	  embedded into the hba struct. lpfc_config_setup() has been
+	  removed.
+	* Collapsed lpfc_scsi_cmd_start into lpfc_queuecommand and cleaned
+	  up combined routines.
+	* Removed unused prototypes myprint and
+	  lpfc_sched_service_high_priority_queue.
+	* Removed unused function lpfc_nodev.
+	* Removed scsi_cmnd->timeout_per_command cancelation. SCSI midlayer
+	  now times out all commands - FW is instructed to not timeout.
+	* Removed polling code from lpfc_scsi_cmd_start. Reorganized
+	  queuecommand and cmd_start some.
+
+Changes from 20040810 to 20040823
+
+	* Changed version number to 8.0.10
+	* Additional timer changes as per Arjan / Christoph's comments.
+	* Used mod_timer() instead of del_timer_sync() where appropriate.
+	* Fixed a use after free case (panic on 2.6.8.1 with
+	  CONFIG_DEBUG_SLAB set).
+	* Fix compile warning in lpfc_fcp.c.
+	* Minor fix for log message, that prints unassigned brdno which is
+	  zero.
+	* Move scsi_host_alloc() to the beginning of probe_one(). This
+	  ensures that host_lock is available at later stages and also
+	  avoids tons of unnecessary initializing if host_alloc()
+	  fails.
+	* Removed else clause from lpfc_slave_configure that set
+	  sdev->queue_depth.  The driver informs the midlayer of its
+	  setting in the template and only overrides if queue tagging is
+	  enabled.
+	* Added PCI_DEVICE_ID_ZEPHYR and PCI_DEVICE_ID_ZFLY (Junior
+	  Zephyr) support
+
+Changes from 20040730 to 20040810
+	
+	* Changed version number to 8.0.9
+	* Removed per HBA driver lock.  Driver now uses the host->host_lock
+	* Restored support for the 2.6.5 kernel for those linux distributions
+	  shipped with the 2.6.5 kernel.
+	* Applied patch from Christoph Hellwig (hch@infradead.org) as follows
+	  "[PATCH] use scsi host private data in ->proc_info.  
+	* Applied patch from Christoph Hellwig (hch@infradead.org) as follows
+	  "Re: [Emulex] Ready for next round.  This patch cleans up the memory 
+	  allocation routines a little and fixes a missing mempool_destroy and
+	  some missing error handling."
+	* Changed pointers assignments from 0 to NULL.
+	* Added fixes to the lpfc_reset_lun_handler and lpfc_reset_bus_handler
+	  entry points that caused kernel to Oops or hang.
+	* Added fixes to targetless hosts that caused modprobe and insmod to hang.
+	* Ongoing cleanup to many files
+

+	  already available elsewhere.
+	* Applying "Streamline lpfc error handling" patch from Christoph
+	  Hellwig (hch@infradead.org) with following modifications: fix
+	  mem leaks, remove some misplaced code that need not be there,
+	  print a message on exit (old code prints two (entry/exit)), make
+	  ret values consistent (either 1/0 or SUCCESS/FAILURE), keep all
+	  eh routines in a single file (lpfc_scsiport.c).
+	* Move contents of lpfc_module_param.h into lpfc_fcp.c.
+	* Changed sysfs attributes to CLASS_DEVICE_ATTRIBUTES (previously
+	  DEVICE_ATTRIBUTES). They now appear in
+	  /sys/class/scsi_host/hostx (previously in
+	  /sys/bus/pci/drivers/lpfc/devx).
+	* Removed lpfc_syfs.h and lpfc_sysfs.c.
+	* Cleanup of config params.  Throttle params have been removed.

+	  code.
+	* Changed DMABUF_t usage to struct lpfc_dmabuf.
+	* Downsizing iCfgParam structure to include a_string, a_low, a_hi
+	  and a_default values only.
+	* Free SCSI buf safety memory pool on shutdown to eliminate memory
+	  leak.
+	* Change lpfc_printf_log to a #define. Also include phba->brd_no
+	  and newline in the print string rather than in the #define.
+	* Remove code that optionally locates Host Group Pointers in host
+	  memory SLIM since this is no longer needed for PPC64, once
+	  CONFIG_PORT uses HBA's view of its BAR0.
+	* Removed the forward declarations of the sli functions and
+	  rearranging the code in lpfc_sli.c.
+	* Removed the preamble functionality from logging.
+	* Make lpfc_sli_hba_setup() return negative error codes on error
+	  and correct the comment left over in lpfc_fcp.c
+	* Removed the lpfc_loadtime variable.
+	* Put a space between all ifs and their open parens '('.
+	* Change Studly_Caps LPFC_SCSI_BUF_t to struct lpfc_scsi_buf.
+	* Fixed insmod hang after hardware error.
+	* Relocated scsi_host alloc to before we enable the interrupt
+	  handler
+	* Add .tmp_versions directory to Makefile clean target.  This
+	  directory is created in the 2.6.5+ build process (with Red Hat
+	  kernels at least).
+	* Changing phba->config to kmalloc lpfc_icfgparam and not
+	  *phba->config. This is manifesting itself as a panic in
+	  pci_release_region().
+	* Fix for firmware download / board reset problem.
+	* Integrated patch from Christoph Hellwig (hch@infradead.org) to
+	  reorganize and cleanup lpfc_fcp.c
+	* Don't abort commands immediately when there is an RSCN event to
+	  give driver time to rediscover targets before the midlayer
+	  retries the SCSI commands.
+
+Changes from 20040604 to 20040614
+
+	* Changed version number to 8.0.4
+	* Removed lpfc_valid_lun function.
+	* Added scsi_buf safety pool to address scsi_buf failures in
+	  queuecommand under low memory conditions.  Allocations now come
+	  from kmalloc initially, but if kmalloc fails, the allocation
+	  comes from the safety pool.
+	* Modified lpfc_slave_alloc to only set the scsi_device->hostdata
+	  pointer if the driver has discovered the target.  This routine
+	  always returns success now as well since no error ever occurs in
+	  the alloc routine.
+	* Mask only info and warning messages.  Print all error messages
+	  irrespective of mask.
+	* Removing lpfc_log_chk_msg_disabled()
+	* Changed lpfc_printf_log to take struct lpfc_hba * directly
+	  instead of a "board number".
+	* Convert dma_sync_single to pci_dma_sync_single_for_{device/cpu}.
+	* Implemented new style log messages. The message strings are now
+	  embedded in the call to lpfc_printf_log.
+	* Decreased FLOGI discovery timeout to 20 seconds.
+	* On error in lpfc_pci_probe_one() return -1 and not 1.
+	* Allow for board numbers that are not sequential, paving the way
+	  for hotplug support.
+	* scsi_add_host() can fail, so wrap it around in an if(). Also
+	  initiate scsi_scan_host() after attaching the sysfs attributes.
+	* lpfc_release_version is used only in lpfc_ct.c, so move it there
+	  and mark it as static.
+	* Removed lpfc_sleep_ms and replaced with mdelay or schedule calls
+	  directly
+	* Removed all (struct list_head *) casts from clkData-related list
+	  handling in list_add, list_del macros.
+	* Removed EXPORT_SYMBOLs.
+	* Removed LPFC_MIN_QFULL and lpfc_qthrottle_up.
+	* Replace LPFCSCSITARGET_t with struct lpfc_target.
+	* Replace LPFCSCSILUN_t with struct lpfc_lun.
+	* Remove unused struct declarations (fcPathId and fcRouteId) from
+	  lpfc_scsi.h.
+	* Rewrite use of FC transport attributes.
+	* Fix crash when link is lost.  This was due to lpfc_delay_iodone
+	  calling list_del on an object that was never put on a list.
+	* Remove trailing spaces at the end of all lines.
+	* Set MAX_FCP_TARGET to 256 from 0xff.  Set MAX_FCP_LUN and
+	  MAX_FCP_CMDS to their decimal equivalents and updated
+	  documentation.
+
+Changes from 20040526 to 20040604
+
+	* Changed version number to 8.0.3
+	* Completed sysfs FC transport support.
+	* Removed unused fields in SCSI LUN and SCSI Target structures:
+	  void *pTargetProto; void *pTargetOSEnv; void *pLunOSEnv;
+	* Modified list_for_each to list_for_each_entry. Modified
+	  list_for_each_safe to list_for_each_entry_safe.
+	* Remove lpfc_dfc.h file.
+	* Changed pHba->phba, pCommand->pcmd
+	* Changed plogi_ndlp -> plogindlp, pos_tmp->postmp, pRsp->prsp,
+	  pCmd->pcmd
+	* Changed pText -> ptext
+	* Changed p_tmp_buff -> ptmpbuff
+	* Changed pBufList -> pbuflist, pRsp -> prsp, pCmd -> pcmd
+	* Changed *pos_tmp -> *postmp, *p_mbuf -> *pmbuf
+	* Following changes are made to the SCSI fast path: Added
+	  DMA_BUF_t member to the lpfc_scsi_buf_t.  This will reduce a
+	  memory allocation in the scsi fast path.  Added check for
+	  targetp == NULL in the scsi fast path.  Increased number of
+	  scatter gather entries in lpfc_scsi_dma_ext to 4 from 3 and
+	  changed the size of lpfc_scsi_dma_ext to 264
+	* Fixing some missing static lpfc_nportdisc.c.
+	* Reordered #include lines so that lpfc.h doesn't have to #include
+	  other header files.
+	* Remove lpfc_get_hba_sym_node_name() as a global EXPORT and make
+	  it static.
+	* Move struct clk_data definition from lpfc_hw.h to lpfc_sli.h.
+	* Changed LPFC_IOCBQ_t to struct lpfc_iocbq.
+	* Changed LPFC_SLI_RING_t to struct lpfc_sli_ring.
+	* Changed LPFC_NODELIST_t to struct lpfc_nodelist.
+	* Rearranged lpfc_nportdisc.c by moving state machine array
+	  (lpfc_disc_action) and the one function that uses it,
+	  lpfc_disc_state_machine, to the end of the file, removing the
+	  need for the raft of prototypes at the top.
+	* Changed LPFC_BINDLIST_t to struct lpfc_bindlist.
+	* Removed lpfc_issue_ct_rsp(), lpfc_sleep(), lpfc_add_bind(),
+	  lpfc_del_bind(), lpfc_sli_wake_mbox_wait() and
+	  lpfc_sli_issue_mbox_wait().
+	* Fixed a large number of overly-long lines.
+	* Fixed some discovery problems: Introduced deferred ndlp removal
+	  when in DSM to avoid panic when in nested DMSs Fix NportId
+	  fffc01 handling to not relogin after LOGO fixed handling of LOGO
+	  on PLOGI issue.
+	* Changed SLI_CT_REQUEST to lpfc_sli_ct_request.
+	* Changed NAME_TYPE to struct lpfc_name.
+	* Changed lpfcCfgParam_t to struct lpfc_cfgparam.
+	* Changed LPFC_STAT_t to struct lpfc_stats.
+	* Changed HBAEVT_t to struct lpfc_hba_event.
+	* Changed Studly_Caps lpfcHBA_t to struct lpfc_hba.
+	* Removed no longer used tasklet_running flag.
+	* Removing *PSOME_VAR typedefs and using SOME_VAR* directly.
+	* Changing .use_clustering to ENABLE_CLUSTERING.
+	* Modify lpfc_queuecommand to return SCSI_MLQUEUE_HOST_BUSY when
+	  it can't queue a SCSI command.  Also, remove cmnds_in_flight
+	  member of struct lpfcHBA for 2.6 kernels as it was only needed
+	  to determine what to return from queuecommand.
+	* Change return type of lpfc_evt_iocb_free to void as it doesn't
+	  return anything.
+	* Remove unused cmnd_retry_list and in_retry members in struct
+	  lpfcHBA.
+	* Remove some instances of unneeded casting of kmalloc's return in
+	  lpfc_scsiport.c
+	* Remove lpfc_linux_attach() and lpfc_linux_detach(). Integrate
+	  them into lpfc_probe_one() and lpfc_release_one() respectively.
+	* Remove lpfc_num_iocbs, lpfc_num_bufs module parameters
+	* Remove #defines for NUM_NODES, NUM_BUFS and NUM_IOCBS
+
+Changes from 20040515 to 20040526
+
+	* Changing version number to 8.0.2.
+	* Including dma-mapping.h as one of the include headers.  Also
+	  rearrange the #include order.
+	* Make functions static as appropriate.
+	* queuecommand() will now return SCSI_MLQUEUE_HOST_BUSY instead of
+	  1 to backpressure midlayer.
+	* Removed function prototypes for lpfc_start_timer() and
+	  lpfc_stop_timer()
+	* Changed timer support to be inline.  Clk_data is now declared
+	  right next to the corresponding timer_list entry so we don't
+	  have to allocate these clk_data dynamically.
+	* Add readls after writels to PCI space to flush the writes.
+	* Fix misspelled word "safety" in function names.
+	* Fix up comments in lpfc.conf for per HBA parameters to reflect
+	  new implementation.
+	* Change lpfc_proc_info handler to get the Nodename from
+	  fc_nodename and not fc_portname.
+	* Fix up some comments and whitespace in lpfc_fcp.c.
+	* Formatting changes: get rid of leading spaces in code

+	  elx_sched_init after READ_CONFIG to get max_xri from the
+	  firmware.  Reset ELX_CFG_DFT_HBA_Q_DEPTH to max_xri after
+	  READ_CONFIG
+	* Fix fc_get_cfg_parm() to be more robust and support embedded hex
+	  values.  The lpfc_param's are now defined as:
+	  lpfc_log_verbose="lpfc:0,lpfc0:0x10,lpfc1:4,lpfc100:0xffff" The
+	  "," delimter does not matter. It can be anything or not exist at
+	  all. ie param = "lpfc:0lpfc0:0x10.lpfc1:4txtlpfc100:0xffff" will
+	  also work.  Additionally the string is treated as case
+	  insensitive.
+	* Changed all usage of lpfc_find_lun_device() to lpfc_find_lun().
+	* Removed unnecessary wrappers lpfc_find_lun_device() and
+	  lpfc_tran_find_lun().
+	* Switch from using internal bus/id/lun to similar data from
+	  scsi_device structure.
+	* Eliminate one-line function lpfc_find_target()
+	* Added slave_alloc, slave_destory
+	* lpfc_scsi_cmd_start can now acquire lun pointer from
+	  scsi_device->hostdata, which is setup in slave_alloc.
+	* Eliminate unnecessary checking on every cmd just to see if we
+	  are accessing the device the first time.
+	* Remove assumption in lpfc_reset_lun_handler that a valid
+	  lpfc_scsi_buf is hung off of linux's scsi_cmnd->host_scribble
+	  when our reset is called.
+
+Changes from 20040507 to 20040515
+
+	* Changed version to 8.0.1
+	* Fixed crash on driver rmmod after error injection tests and
+	  lpfc_tasklet deadlock.

+	* Removed string "Open Source" from MODULE_DESC
+	* Cleanup duplicated string definitions used by MODULE_DESC
+	* Renamed lpfc_pci_[detect|release] to lpfc_pci_[probe|remove]_one
+	* Fix formatting of lpfc_driver
+	* Remove unnecessary memset to 0 of lpfcDRVR

+	* Remove phba->iflag reference.
+	* Several locking improvements.
+	* Remove functions lpfc_drvr_init_lock, lpfc_drvr_lock,
+	  lpfc_drvr_unlock and lpfc_hipri_*.
+	* Remove LPFC_DRVR_LOCK and LPFC_DRVR_UNLOCK macros.
+	* Make lpfc_info() use lpfc_get_hba_model_desc() instead of
+	  rewriting almost identical code.
+	* Fix 1 overly long line in each of lpfc_cfgparm.h, lpfc_ftp.c and
+	  lpfc_sli.c.
+	* Fix build for Red Hat 2.6.3 kernel by #defining MODULE_VERSION
+	  only if it isn't already defined.
+	* Change elx_sli_issue_mbox_wait to return correct error code to
+	  the caller.
+	* In some of the els completion routines, after calling
+	  lpfc_elx_chk_latt, driver ignores the return code of the
+	  lpfc_elx_chk_latt. This will prevent the discovery state machine
+	  restarting correctly when there are link events in the middle of
+	  discovery state machine running. Fix this by exiting discovery
+	  state machine if lpfc_els_chk_latt returns a non zero value.
+	* Removed MAX_LPFC_BRDS from lpfc_diag.h
+	* Removed unused first_check.
+	* Remove some unused fields and defines.
+	* Change lpfc-param names to lpfc_param.

+	* Move the definition of MAX_LPFC_BRDS to the only header file
+	  that uses it (lpfc_diag.h).
+	* Change lpfc_sli_wake_iocb_wait to do a regular wake_up since
+	  lpfc_sli_issue_iocb_wait now sleeps uninterruptible.
+	* Replace list_for_each() with list_for_each_safe() when a list
+	  element could be deleted.
+	* Fix IOCB memory leak
+
+Changes from 20040416 to 20040426
+
+	* Change lpfc_config_port_prep() to interpret word 4 of the DUMP
+	  mbox response as a byte-count

+	  lpfc_instcnt, lpfc_instance[], and pHba[] into lpfcDRVR
+	  structure Added routines lpfc_get_phba_by_inst()
+	  lpfc_get_inst_by_phba() lpfc_check_valid_phba()
+	* Turn on attributes "set" & "params" by default.
+	* Further formatting/whitespace/line length cleanup on: lpfc_ct.c
+	  lpfc_els.c lpfc_fcp.c lpfc_hbadisc.c lpfc_init.c lpfc_ipport.c
+	  lpfc_mbox.c lpfc_nportdisc.c lpfc_sched.c lpfc_sched.h
+	  lpfc_scsi.h lpfc_scsiport.c lpfc_sli.c and lpfc_sli.h

+	  was causing an Oops on 2.6.5 kernel.
+	* Cleanup use of several gotos not used for error exit.
+	* Replace memcpy_toio() and memcpy_toio() with endian-dependent
+	  lpfc_memcpy_to_slim() and lpfc_memcpy_from_slim() so that for
+	  big endian hosts like PPC64, the SLIM is accessed 4 bytes at a
+	  time instead of as a byte-stream.
+
+Changes from 20040409 to 20040416
+
+	* The scsi_register and scsi_alloc_host OS calls can fail and
+	  return a zero-valued host pointer.  A ctrl-C on 2.6 kernels
+	  during driver load will cause this and the driver to panic.
+	  Fixed this bug.  Also found a bug in the error_x handling with
+	  lpfc_sli_hba_down - it was in the wrong place and the driver
+	  lock was not held, but needed to be (in lpfc_linux_attach) Fixed
+	  both.  Did some minor comment clean up.
+	* Removed unwanted (void *) castings.
+	* Replace define of INVALID_PHYS, with kernel 2.6.5's
+	  dma_mapping_error() and add a inline function for earlier
+	  kernels.  Remove lpfc_bad_scatterlist().
+	* Clean up formatting in hbaapi.h, lpfc.h, lpfc_cfgparm.h,
+	  lpfc_crtn.h, lpfc_ct.c, lpfc_diag.h, lpfc_disc.h, lpfc_els.c,
+	  lpfc_fcp.c, lpfc_hbadisc.c, lpfc_hw.h, lpfc_init.c,
+	  lpfc_ipport.c, lpfc_logmsg.c, lpfc_logmsg.h and lpfc_scsiport.c
+	  - mostly replacing groups of 8 spaces with hard tabs and keeping
+	  lines to 80 column max..
+	* Removed LPFC_DRVR_LOCK call from lpfc_unblock_requests for 2.4
+	  kernels.  The lpfc_scsi_done routine already unlocks the driver
+	  lock since it expects this lock to be held.
+	* Removed global lock capabilities from driver lock routines
+	* Remove SA_INTERRUPT flag from request_irq
+	* Move dma_addr_t cast inside of getPaddr macro as everywhere
+	  getPaddr is used, the return is cast to dma_addr_t.
+	* Clean up formatting in lpfc_sli.c and lpfc_sysfs.c - mostly
+	   replacing groups of 8 spaces with hard tabs and keeping lines
+	   to 80 column max.
+	* Fix build for RHEL 2.1 BOOT kernels by always #including
+	  interrupt.h in lpfc.h.
+	* Fix RHEL 3 build by #defining EXPORT_SYMTAB.

+	* Fix build warnings on 2.6 kernels - remove no longer used calls
+	  to  character device initialization.
+	* Initial support code for discovery in tasklet conversion.
+	* Removing char interface and ioctl code.
+	* Change all elx prefixes to lpfc
+	* Replace lpfc_write_slim() & lpfc_read_slim() with memcpy_toio(),

+	* Replace lpfc_read/write_CA/HA/HC/HS with calls to readl() &
+	  writel() directly.
+	* Increase SLI2_SLIM to 16K Increase cmd / rsp IOCBs accordingly
+	* Removed lpfc_els_chk_latt from the lpfc_config_post function.
+	  lpfc_els_chk_latt will enable the link event interrupts when
+	  flogi is pending which causes two discovery state machines
+	  running parallely.
+	* Add pci_disable_device to unload path.
+	* Move lpfc_sleep_event from lpfc_fcp.c to lpfc_util_ioctl.c
+	* Call dma_map_single() & pci_map_single() directly instead of via
+	  macro lpfc_pci_map().  Allow address 0 for PPC64.

+	* Replace mlist->dma.list = dmp->dma.list; to mlist = dmp.
+	* Remove functions lpfc_get_OsNameVersion and elx_wakeup. Change
+	  elx_wakeup to wake_up_interruptible
+	* Add function lpfc_get_os_nameversion and change
+	  lpfc_get_OsNameVersion to lpfc_get_os_nameversion.
+	* Remove lpfc_get_OsNameVersion
+	* Change driver name to a consistent lpfc in every visible place.
+	* Fix build warning: removed unused variable ret in lpfc_fdmi_tmo.
+	* Remove lpfc_utsname_nodename_check function
+	* Remove functions lpfc_register_intr and lpfc_unregister_intr
+	* Fill in owner field in lpfc_ops file_operations struct and

+	  els_timeout routine.  It now stops all timeout routines
+	  associated with that hba.
+	* Replace seperate next and prev pointers in struct
+	  lpfc_bindlist with list_head type.  In elxHBA_t, replace
+	  fc_nlpbind_start and _end with fc_nlpbind_list and use
+	  list_head macros to access it.
+	* Fix ulpStatus for aborting I/Os overlaps with newer firmware
+	  ulpStatus values

+	* Wrapped lpfndd.o target in BUILD_IPFC ifdef.
+	* Removed elx_os.h inclusion in implementation files.
+	* Removed ELX_OS_IO_t data structure and put data direction
+	  and non scatter/gather physical address into the scsi buffer
+	  structure directly.  Moved DRVR_LOCK, putPaddr, getPaddr
+	  macros and some defines into elx.h since they are required
+	  by the whole driver.

+	  attribute "set" to be used in conjuction with the above
+	  attributes.
+	* Removed DLINK, enque and deque declarations now that clock
+	  doesn't use them anymore
+	* Separated install rule so that BUILD_IPFC has to be set when
+	  make is called in order for the install rule to attempt to
+	  copy the lpfndd.o driver.  This change fixes a bug that
+	  occurs because the install rule by default attempted to
+	  install lpfndd.o, whereas the default make rule did not by
+	  default build lpfndd.o.
+	* Keep track if hbaapi index numbers need to be refreshed.
+	* Removed prod_os.h from include list.
+	* Removed LPFC_LOCK and LPFC_UNLOCK macros.  Added OS calls
+	  into elx_os_scsiport.c.  This file is now empty.

+	  into code directly and removed LPFC_LOCK_ and _UNLOCK_
+	  macros
+	* Remove references to "elx_clock.h"
+	* Added utsname.h to include list.  The previous checkin to
+	  elx_os.h removed its inclusion of utsname.h since there is
+	  precious little in the file.  However, lpfcLINUXfcp.c needs
+	  it and now has it.
+	* Removed some commented-out code
+	* Removed elx_lck_t data structure, stray elxDRVR_t type, and
+	  include from file.  No longer used.
+	* Removed two PCI Sync defines.  Removed includes - not
+	  needed.  Cleaned up macro lines.
+	* Added two functions from elxLINUXfcp.c.  These functions
+	  were IPFC specific.

+	  Removed elx_lck_t and added spinlock_t directly. Moved two
+	  IPFC functions into lpfc_ipport.c
+	* Moved IP specific structures to lpfc_ip.h file.
+	* lpfc_ipfarp_timeout() uses system timer.  Remove all usages
+	  of old internal clock support.
+	* Made changes to compile without IPFC support for the default
+	  build.  Added ifdef IPFC for all lpfc_ip.h includes.
+	* Patched elx_free_scsi_buf
+  	* Removed elx_sched.o from 2.6 dependencies
+	* Reworked lpfc_pcimap.

+          timer.
+	* Removed num_bufs and num_iocbs configuration parameters.
+	* Fixed a memory corruption bug. This was caused by a memory
+	  write to ndlp structure from lpfc_cmpl_els_acc function.
+	  This ndlp structure was freed from lpfc_els_unsol_event.
+	* lpfc_disc_timeout() and lpfc_establish_link_tmo() now use
+	  system timer.  Also update lpfc_els_retry_delay() to do a
+	  single lock release at the end.
+	* Remove use of PAN (pseudo adapter number).
+	* Reintroduced usage of the cross compiler for building on
+	  ppc64 to remove build errors that were cropping up when
+	  using the standard gcc compiler.
+	* Fix no-unlock-before return in lpfc_els_retry_delay which was
+	  causing  a deadlock on insmod in some environments.
+	* Minor format changes fix up comments
+	* Create utility clock function elx_start_timer() and
+	  elx_stop_timer().  All timeout routines now use these common
+	  routines.

+	  declaration.
+	* Cleanup casting around DMA masks.
+	* Comment out lpfndd.o modules_install section as lpfndd.o is
+	  not generated if CONFIG_NET_LPFC is not set. Also refer to

+	  will not exist otherwise.
+	* Removed unused malloc counters from lpfcLINUXfcp.c.
+	* Remove some unnecessary #includes in lpfcLINUXfcp.c

+LPFC Driver Release Notes:
+
+=============================================================================
+
+
+                               IMPORTANT:
+
+  Starting in the 8.0.17 release, the driver began to be targeted strictly
+  toward the upstream kernel. As such, we removed #ifdefs for older kernels
+  (pre 2.6.10). The 8.0.16 release should be used if the driver is to be
+  run on one of the older kernels.
+
+  The proposed modifications to the transport layer for FC remote ports
+  and extended attribute support is now part of the upstream kernel
+  as of 2.6.12. We no longer need to provide patches for this support,
+  nor a *full* version which has old an new kernel support.
+  
+  The driver now requires a 2.6.12 (if pre-release, 2.6.12-rc1) or later
+  kernel.
+  
+  Please heed these dependencies....
+
+
+   ********************************************************************
+
+
+The following information is provided for additional background on the
+history of the driver as we push for upstream acceptance.
+
+Cable pull and temporary device Loss:
+
+  In older revisions of the lpfc driver, the driver internally queued i/o 
+  received from the midlayer. In the cases where a cable was pulled, link
+  jitter, or a device temporarily loses connectivity (due to its cable
+  being removed, a switch rebooting, or a device reboot), the driver could
+  hide the disappearance of the device from the midlayer. I/O's issued to
+  the LLDD would simply be queued for a short duration, allowing the device
+  to reappear or link come back alive, with no inadvertant side effects
+  to the system. If the driver did not hide these conditions, i/o would be
+  errored by the driver, the mid-layer would exhaust its retries, and the
+  device would be taken offline. Manual intervention would be required to
+  re-enable the device.
+
+  The community supporting kernel.org has driven an effort to remove
+  internal queuing from all LLDDs. The philosophy is that internal
+  queuing is unnecessary as the block layer already performs the 
+  queuing. Removing the queues from the LLDD makes a more predictable
+  and more simple LLDD.
+
+  As a potential new addition to kernel.org, the 8.x driver was asked to
+  have all internal queuing removed. Emulex complied with this request.
+  In explaining the impacts of this change, Emulex has worked with the
+  community in modifying the behavior of the SCSI midlayer so that SCSI
+  devices can be temporarily suspended while transport events (such as
+  those described) can occur.  
+
+  The proposed patch was posted to the linux-scsi mailing list. The patch
+  is contained in the 2.6.10-rc2 (and later) patch kits. As such, this
+  patch is part of the standard 2.6.10 kernel.
+
+  By default, the driver expects the patches for block/unblock interfaces
+  to be present in the kernel. No #define needs to be set to enable support.
+
+
+Kernel Support
+
+  This source package is targeted for the upstream kernel only. (See notes
+  at the top of this file). It relies on interfaces that are slowing
+  migrating into the kernel.org kernel.
+
+  At this time, the driver requires the 2.6.12 (if pre-release, 2.6.12-rc1)
+  kernel.
+
+  If a driver is needed for older kernels please utilize the 8.0.16
+  driver sources.
+
+
+Patches
+
+  Thankfully, at this time, patches are not needed.
