This patch fixes an issue seen where an event occurs
which causes the ibmvscsi driver to reset its CRQ. Upon
re-registering its CRQ, it receives H_CLOSED, indicating
the Virtual I/O Server is not yet ready to receive commands.
This resulted in the ibmvscsi driver essentially offlining
the adapter and not recovering. The fix is to re-enable
our interrupt so that when the Virtual I/O server is ready
and sends a CRQ init, we will be able to receive it and
resume initialization of the VSCSI adapter.

Currently the size of the dump generated by the driver is limited
in 4MB, which is insufficient to gather much useful data from the
new 64 bit adapters.

This patch makes the needed changes to increase the dump limit
for the 64 bit adapters to 32MB, or even to a bigger value in the
future, but keeping the current limitations for the legacy 32 bit
adapters.

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.

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.

moves all netdev cleanup and its releasing inside

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
