Currently NetApp's VID/PID details in the INQUIRY response shows up as
'NETAPP' and 'LUN'. With upcoming scalable SAN ONTAP version on NetApp
controllers, the PID entry alone is being modified to 'LUN C-Mode' (to
distinguish current ONTAP LUNs from scalable ONTAP LUNs).
'LUN' would still suffice for matching 'LUN C-Mode' but best to
explicitly add these new NetApp LUNs to the device list.

submit_stpg() will always return failure so alua_activate() will report
failure via dm-multipath callback function. Even though the stpg fired
successfuly dm-multipath does not know and always fails to change the
valid path.
By returning SCSI_DH_OK we're now skipping alua_activate()'s call to
activate_complete 'fn'. But this is fine because stpg_endio() will call
it via h->callback_fn().

Basic Code Cleanup:
(1) _base_get_cb_idx and mpt2sas_base_free_smid were reorganized in
similar fashion so the order of obtaining the cbx and smid are
scsiio,
hi_priority, and internal.
(2) The hi_priority and internal request queue struct was made
smaller
by removing the scmd and chain_tracker, thus saving memory
allocation.
(3) For scsiio request, a new structure was created having the same
elements from the former request tracker struct.

SDEV_MEDIA_CHANGE event was first added by commit a341cd0f (SCSI: add
asynchronous event notification API) for SATA AN support and then
extended to cover generic media change events by commit 285e9670
([SCSI] sr,sd: send media state change modification events).
This event was mapped to block device in userland with all properties
stripped to simulate CHANGE event on the block device, which, in turn,
was used to trigger further userspace action on media change.
The recent addition of disk event framework kept this event for
backward compatibility but it turns out to be unnecessary and causes
erratic and inefficient behavior. The new disk event generates proper
events on the block devices and the compat events are mapped to block
device with all properties stripped, so the block device ends up
generating multiple duplicate events for single actual event.
This patch removes the compat event generation from both sr and sd as
suggested by Kay Sievers. Both existing and newer versions of udev
and the associated tools will behave better with the removal of these
events as they from the beginning were expecting events on the block
devices.

Replace sd_media_change() with sd_check_events().
* Move media removed logic into set_media_not_present() and
media_not_present() and set sdev->changed iff an existing media is
removed or the device indicates UNIT_ATTENTION.
* Make sd_check_events() sets sdev->changed if previously missing
media becomes present.
* Event is reported only if sdev->changed is set.
This makes media presence event reported if scsi_disk->media_present
actually changed or the device indicated UNIT_ATTENTION. For backward
compatibility, SDEV_EVT_MEDIA_CHANGE is generated each time
sd_check_events() detects media change event.

The semantics we employ now in the driver, performing a
BIG_HAMMER in the event of Get-ID (0x20) mailbox command
failing, should only be done for FC. On FC configurations, it
makes sense since advertising is only really performed once,
so a BIG_HAMMER to reinitiate the process is needed to
restart. Under FCoE, this is not needed, as there's a
continous stream of advertisements/ACks at the protocol layer
to initiate a relogin/reinitialization process.

The FCP priority info was not being updated properly in certain situations.
Here are the changes that needs to be done to take care of this issue:
1. No need to check fcport->state for FCS_UNCONFIGURED in
qla24xx_update_fcport_fcp_prio(), since an invalid loop id check is
already performed which is sufficient.
2. Add the missing qla24xx_update_fcport_fcp_prio() function call
within qla2x00_update_fcport() function, so that the priority info
is updated on every port addition or change.
3. Perform proper adapter types checking.
