pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since commit f26e58bf6f ("PCI/AER: Enable error reporting when
AER is native"), the PCI core does this for all devices during enumeration,
so the driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

bna & bfa firmware version 3.2.5.1 was submitted to linux-firmware on
Feb 17 19:10:20 2015 -0500 in 0ab54ff1dc ("linux-firmware: Add QLogic BR
Series Adapter Firmware").
bna was updated to use the newer firmware on Feb 19 16:02:32 2015 -0500 in
3f307c3d70 ("bna: Update the Driver and Firmware Version")
bfa was not updated. I presume this was an oversight but it broke support
for bfa+bna cards such as the following
04:00.0 Fibre Channel [0c04]: Brocade Communications Systems, Inc.

Inc. 1010/1020/1007/1741 10Gbps CNA [1657:0014] (rev 01)
Currently, if the bfa module is loaded first, bna fails to probe the
respective devices with
[ 215.026787] bna: QLogic BR-series 10G Ethernet driver - version: 3.2.25.1
[ 215.043707] bna 0000:04:00.2: bar0 mapped to ffffc90001fc0000, len 262144

[ 215.090644] bna 0000:04:00.3: initialization failed err=1
Whereas if bna is loaded first, bfa fails with
[ 249.592109] QLogic BR-series BFA FC/FCOE SCSI driver - version: 3.2.25.0
[ 249.610738] bfa 0000:04:00.0: Running firmware version is incompatible with the driver version

This patch re-implements LUN Masking feature using SCSI Slave Callouts. With
the new design in the slave_alloc entry point; for each new LUN discovered we
check with our internal LUN Masking config whether to expose or to mask this
particular LUN. We return -ENXIO (No such device or address) from slave_alloc
for the LUNs we don't want to be exposed. We also notify the SCSI mid-layer
to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking
is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based
scan translates to a scan abort. This patch also handles the dynamic lun
masking config change from enable to disable or vice-versa by resetting
sdev_bflags of LUN 0 appropriately.

- Modified the design such that each BFA sub-module will provide
the amount of DMA and KVA memory needed by it and queues the
same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
needed by all the BFA sub-modules as one contiguous chunk.

This patch fixes 3 bugs in vport create/delete.
1) Replace scsi_add_host() with scsi_add_host_with_dma()
2) Fix rmmod hang when there are vports configured. This is due to a race
condition between the workqueue destroy in pci remove context and the vport
delete works being handled. The fix is to use a counter to track the
vport delete work, so that workqueue destroy will not be called until all
configured vports are deleted from workqueue.
3) Fix rmmmod crash when there are PBC vport configured. PBC is not allowed
to be deleted dynamically. However, if someone try to delete it, it leaves the
vport is wrong state. The fix is to restore the vport back to original state
when the attempt to delete pbc vport delete is failed.

bfad.c & bfad_drv.h:
* Created a kernel thread from pci_probe that does the bfad start
operations after BFA init done on a firmware mismatch.
* The kernel thread on a fw mismatch waits for an event from IOC
call back and is woken up from bfa_cb_init() on BFA init success.
* In normal cases of no firmware mismatch this thread is terminated
in pci_probe.
bfa_fcs_lport.c, fabric.c, fcs_lport.h & vport.c:
* Split the lport init to attach time and init time code, so that
proper config attributes are set after firmware mismatch.
bfa_iocfc.c:
