The alua device handler starts the first retry after 10 seconds,
and increases it times 10 for each round.
This leads to an unnecessary delay. This patch modifies it to
start after one second, and increase by a factor of two.

For Target Portal Group IDs occupying the full 2 bytes in the
RTPG response, the following group_id check in the alua_rtpg
routine always fails in scsi_dh_alua.c:
if (h->group_id == (ucp[2] << 8) + ucp[3]) {
This causes the ALUA handler to wrongly identify the AAS of
a specified device as well as incorrectly interpreting the
supported AAS of the target as seen by the following entries
in the /var/log/messages:
"alua: port group 3ea state A supports tousna"
"alua: port group 3e9 state A supports tousna"
This is because 'ucp' is wrongly declared in alua_rtpg as
a character pointer instead of an unsigned character pointer.

Some device handler types are not tied to the vendor/model
but rather to a specific capability. Eg ALUA is supported
if the 'TPGS' setting in the standard inquiry is set.
This patch implements a 'match' callback for device handler
which supersedes the original vendor/model lookup and
implements the callback for the ALUA handler.

->queuecommand must return either 0, or one of the SCSI_MLQUEUE_* return
values. Non-transient errors are indicated by setting cmd->result before
calling ->scsi_done and returning 0. Fix libsas to adhere to this calling
convention. Note that the DID_ERROR for returns from the low-level driver
might not be correct for all cases, but it's the best we can do with
the current layering in libsas. I also suspect that the pre-existing
handling of -SAS_QUEUE_FULL should really be SCSI_MLQUEUE_HOST_BUSY, but
I'll leave that for a separate change.

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.

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:

Current fc_eh_host_reset leaves lport offline
permanently due to FLOGI response getting
handled by LOGO response from last reset as both
had same exchange id.
So fix this by having end to end exches clean-up
using exchange abort along exches reset
done from fc_eh_host_reset. This would avoid
exchanges collision between the sessions across
the reset. In this case implicit login should have
done that but no aborting support for FIP
frames, so just wait till lport->r_a_tov before
restarting next flogi to ensure all exchanges
are good to use again for next session.
Below is the trace of LOGO from older session

The rtnl cannot be held durrng the fcoe_interface_put.
If it is the last reference on the fcoe_interface the
fcoe_ctlr_destroy will be called as a part of the
cleanup, ultimately calling cancel_work_sync(&fip->recv_work);
If we are processing a flogi response we will be in
the recv_work context and we will lock the rtnl to
add a new unicast MAC address. This is how the deadlock
can occur.
The fix is simply to move the rtnl_lock/unlock into
fcoe_interface_cleanup so that it can be unlocked before
fcoe_interface_put is called.
Here is the lockdep report:

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

Added new sysfs attr 'host_reset' in scsi_sysfs.c to
perform adapter or firmware reset as suggested by
Mike Christie here:
http://marc.info/?l=linux-scsi&m=127359347111167&w=2
user/application can write "adapter" or "firmware" on
this attr and it will call newly added function hook
in scsi_host_template to call LDD adapter or firmware
reset implementation.

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.
