To add the Online controller reset support, driver need to do:
a). reset the controller chips -- Xscale and Gen2 which will change
the function calls and add the reset function related to this two
chips.
b). during the reset, driver will store the pending cmds which not
returned by FW to driver's pending queue. Driver will re-issue those
pending cmds again to FW after the OCR finished.
c). In driver's timeout routine, driver will report to OS as reset.
Also driver's queue routine will block the cmds until the OCR
finished.
d). in Driver's ISR routine, if driver get the FW state as state
change, FW in Failure status and FW support online controller
reset (OCR), driver will start to do the controller reset.
e). In driver's IOCTL routine, the application cmds will wait for the
OCR to finish, then issue the cmds to FW.

If a Virtual I/O server is rebooted, the client fibre channel sees a
transport event on its CRQ, which causes it to attempt to reconnect
to the CRQ. For a period of time during the VIOS reboot, the client's
attempts to register the CRQ will return H_CLOSED, indicating the server
side is not currently registered. The ibmvfc driver was not handling
this well and was taking the virtual adapter offline. Fix this by
re-enabling our interrupt and waiting for the event on our CRQ
indicating the server is back, at which point we can reconnect.

calling into the driver using the get_host_def_dev_loss_tmo

When an rport is "blocked" and a bsg request is received, the bsg request gets
placed on the queue but the queue stalls. If the fc object is then deleted - the
bsg queue never restarts and keeps the reference on the object, and stops the
overall teardown.
This patch restarts the bsg queue on teardown and drains any pending requests,
allowing the teardown to succeed.

The previous thin provisioning support was not very user friendly
because it depended on all the relevant options being set on the command
line.
Implement support for the Thin Provisioning VPD page from SBC3 r24 and
add module options for TPU (UNMAP) and TPWS (WRITE SAME (16) with UNMAP
bit). This allows us to have sane default and to enable thin
provisioning with a simple tpu=1 or tpws=1 on the command line depending
on whether we want UNMAP or WRITE SAME behavior.
