fix bug in adjust_hpsa_scsi_table which caused devices which have
changed size, etc. to do the wrong thing.
The problem was as follows:
The driver maintains its current idea of what devices are present
in the h->dev[] array. When it updates this array, it scans the
hardware, and produces a new list of devices, call it sd[], for
scsi devices.
Then, it compares each item in h->dev[] vs. sd[], and any items which
are not present sd it removes from h->dev[], and any items present
in sd[], but different, it modifies in h->dev[].
Then, it looks for items in sd[] which are not present in h->dev[],
and adds those items into h->dev[]. All the while, it keeps track
of what items were added and removed to/from h->dev[].
Finally, it updates the SCSI mid-layer by removing and adding
the same devices it removed and added to/from h->dev[]. (modified
devices count as a remove then add.)
originally, when a "changed" device was discovered, it was
removed then added to h->dev[]. The item was added to the *end*
of h->dev[]. And, the item was removed from sd[] as well
(nulled out). As it processed h->dev[], these newly added items
at the end of the list were encountered, and sd[] was searched,
but those items were nulled out. So they ended up getting removed
immediately after they were added.
The solution is to have a way to replace items in the h->dev[]
array instead of doing a remove + add. Then the "changed" items.
are not encountered a second time, and removed.

This is done by adding support for the so-called "performant mode"
(that's really what they called it). Smart Array controllers
have a mode which enables multiple command completions to be
delivered with a single interrupt, "performant" mode. We want to use
that mode, as some newer controllers will be requiring this mode.

Currently we're gracefully tearing down each active connection
when fcoe.ko is removed. We shouldn't allow the user to destroy
connections by removing the module. We should force the user to
destroy each connection and then the module can be removed.
This patch makes it so a refrerence count on the module is taken
each time a fcoe_interface is created. The reference count
is dropped when the fcoe_interface is destroyed. This makes it
so that module_exit() doesn't get called unless all fcoe_interfaces
have been destroyed.
This patch leaves the removal of interfaces in the module_exit
routine so that if the user does a 'rmmod -f' we'll clean everything
up before removing the module.
The module_put line was put before the out_putdev goto line because
we should only be decrementing the reference count if a
fcoe_interface is actually destroyed. If we can't find the netdev
or the fcoe_interface then it's assumed that something else has
destroyed the fcoe_interface and it would have decremented the
reference count at that time.

Adds check to call fc_fcp_ddp_setup for only FCP read cmds to avoid
accessing junk fsp pointer at least in ESX since non FCP frame had
junk fsp value, though fsp is implicitly initialized to null
by __alloc_skb but with this patch no more relying on fsp
initialized to null value and hitting junk fsp ptr access.
Removes fsp pointer checking in fc_fcp_ddp_setup as this is not
needed any more since its only caller for FCP read will always
have a valid fsp.

Discovery relates changes:
- Separated VPI_REGISTERED state of physical port into VFI_REGISTERED and
VPI_REGISTERED state so that driver can unregister physical port VPI
independent of VFI.
- Add code to unregister, re-init and re-register physical port VPI
when physical port NportID change.
- Add code to unregister and re-register VPI of a vport when its Nport
ID change.
- Add code in FDISC completion path to re-start FLOGI discovery when
a FDISC complete with LOGIN_REQUIRED reason code.
- Fix a memory leak in lpfc_init_vpi_cmpl
- Add code to start a timer for vport to retry FDISC when CVL is received
by a vport or physical port. If all Nports receive CVLs, then all timers
are cancelled and a logical link level discovery will be started after
one second.
- Flush ELS commands after killing all delayed ELS commands.
