If the session is not ready yet, we ask the SCSI-ml to retry. However, if the
session is just uploaded, we should not retry, but instead call scsi_done to
fail the IO.

fc_remove_host() waits for flushing the workqueue, but it is stuck at flushing
the first work. The first work doesnt complete, because it is waiting for async
layer to complete the IOs. The async layer cannot complete the IO as the
terminate_rport_io for the second work was not called, which will be called
only when the first work completes. Hence the deadlock. To resolve this
deadlock, the workqueue allocation has been modified from
create_singlethread_workqueue() to alloc_workqueue().
In addition, fc_terminate_rport_io() should be called before the
scsi_flush_work() to avoid the similar deadlock as above.
scsi fc alloc queue. move terminate rport io before flush

During performance testing on P7 machines it was observed that the interrupt
service routine was doing unnecessary MMIO operations.
This patch rearranges the logic of the routine and moves some of the code out
of the main routine. The result is that there are now fewer MMIO operations in
the performance path of the code.
As a result of the above change, an existing condition was exposed where the
driver could get an "unexpected" hrrq interrupt. The original code would flag
the interrupt as unexpected and then reset the adapter. After further analysis
it was confirmed that this condition can occasionally occur and that the
interrupt can safely be ignored. Additional code in this patch detects this
condition, clears the interrupt and allows the driver to continue without
resetting the adapter.

This patch has Support for the new solid state device product SSS6200
from LSI and relavent features w.r.t SSS6200.
The major feature added in this driver is supporting Direct-I/O to the
SSS6200 storage.There are some additional changes done to avoid exposing
the RAID member disks to the OS and hiding/exposing drives based on the
OEM Specific Flag in Manufacturing Page10 (this is required to handle
specific changes in the SSS6200 firmware).
Each and every changes are listed below.
1. Hiding IR related messages.
For SSS6200, the driver is modified not to print IR related events.
Even if the debugging is enabled the IR related messages will not be displayed.
In some places if there is a need to display a message related to IR the
string "IR" is replaced with string "DD" and the string "volume" is replaced
with "direct drive". But the function names are not changed hence there are
some places where the reference to volume can be seen if debug level is set.
2. Removed RAID transport support
In Linux the user can retrieve RAID volume information from the sysfs directory.
This support is removed for SSS6200.
3. Direct I/O support.
The driver tries to enable direct I/O when a volume is reported to the driver
by the firmware through IRCC events and the driver does this just before
reporting to the OS, hence all the OS issued I/O can go through direct path
if they can, The first validation is to see whether the manufacturing page10
flag is set to expose all drives always. If that is set, the driver will not
enable direct I/O and displays the message "DDIO" is disabled globally as
drives are exposed. The driver checks whether there is more than one volume
in the controller, if so the direct I/O will be disabled globally for all
volumes in the controller and the message displayed will be "DDIO is disabled
globally as number of drives > 1.
If retrieving number of PD is failed the driver will not enable direct I/O
and displays the message Failure in computing number of drives DDIO disabled.
If memory allocation for RAIDVolumePage0 is failed, the driver will not enable
direct I/O and displays the message Memory allocation failure for
RVPG0 DDIO disabled. If retrieving RAIDVolumePage0 is failed the driver will
not enable direct I/O and displays the message Failure in retrieving
RVPG0 DDIO disabled
If the number of PD in a volume is greater than 8, then the direct I/O will
be disabled.
If any of individual drives handle retrieval is failed then the DD-IO will
be disabled.
If the volume is not RAID0 or if the block size is not 512 then the DD-IO will
be disabled.
If the volume size is greater than 2TB then the DD-IO will be disabled.
If the driver is not able to find a valid stripe exponent using the configured
stripe size then the DD-IO will be disabled
When the DD-IO is enabled the driver will check every I/O request issued to
the storage and checks whether the request is either
READ6/WRITE6/READ10/WRITE10, if it is and if the complete I/O transfer
is within a stripe size then the I/O is redirected to
the drive directly instead of the volume.
On completion of every I/O, if the completion is failure means if the reply
is address reply with a reply frame associated with it, then the type of I/O
will be checked, if the I/O is direct then the I/O will be retried to
the volume once.

Currently fcoe interface cleanup is done after ndo_fcoe_disable
and that prevents logoff going out to the peer, so this patch
moves all netdev cleanup and its releasing inside
fcoe_interface_cleanup to have log off before ndo_fcoe_disable
disables the fcoe.
This patch also fixes asymmetric rtnl locking around fcoe_if_destroy,
as currently this function requires rtnl held by its caller
and then have this func drops the lock, instead now don't have
any processing under rtnl inside fcoe_if_destroy, this required
moving few func to get build working again.

Added REC_TOV_CONST intent was to have rec tov as e_d_tov + 1s
but currently it is e_d_tov + 1ms since e_d_tov is stored in ms
unit.
Also returned rec tov by get_fsp_rec_tov is in ms and this ms tov
is used as-is with fc_fcp_timer_set expecting jiffies tov.
Fixed this by having get_fsp_rec_tov return rec tov in jiffies
as e_d_tov + 1s and then use jiffies tov w/ fc_fcp_timer_set.
Also some cleanup, no need to cache get_fsp_rec_tov return value
in local rec_tov at various places.

individual fcoe transport driver, e.g., fcoe.ko, as sysfs entries now go to

state check for libfcoe will guard the possible race condition of sysfs being

false positive when dealing with the s_active, rtnl
and fcoe_config_mutex mutexes. Recently the create,
destroy, enable and disable sysfs entries were moved
from fcoe.ko to libfcoe.ko. With this change the mutex
usage was shuffled around and the lockdep false
positive stopped happening. We can now remove these

This code was incorrectly ported from fcoe.c when the
fcoe transport infrastructure was put into place. It
was originally needed in fcoe.c when dealing with
the rtnl mutex. In that code it was only needed to
avoid a lockdep false positive. In libfcoe we don't
deal with the rtnl mutex, we don't get the lockdep
false positive and therefore we don't need these

Before driver's own internal state is marked as PLOGI/PRLI
complete. This additional check closes a window seen with
dual-personality initiator/target devices where a driver's
PLOGI/PRLI request occurs within the window after the target's
PLOGI request has completed, but prior to the target's PRLI
arriving and processed by the firmware. Without this additional
check, the firmware will return port-information stating that the
port neither supports target nor initiator functions, causing the
driver to register the rport prematurely to the FC-transport
without the proper 'roles' being set.

handle for Abort I/O IOCBs.
The upper 16-bits of the handle for all I/O in multi-queue supported
drivers carries the ID of the request queue it was submitted on. When
using Abort I/O IOCB, the driver needs to also populate the upper
16-bits in the handle_to_abort field so the fw can correlate with the
actual I/O.

information.
Modifying qla24xx_get_fcp_prio() to return a 'found' status
allows the driver to short circuit the 'set FCP-priority' call
and reduce the amount of noise generated in the messages file:
scsi(5): Unable to activate fcp priority, ret=0x102
scsi(5): Unable to activate fcp priority, ret=0x102
Also make qla24xx_get_fcp_prio() static.
