The logic for sg_seg_cnt is a bit convoluted. This patch tries to clean
up a couple of areas, especially around the +2 and +1 logic.

This patch:

- Cleans up the lpfc_sg_seg_cnt attribute to specify a real minimum
  rather than making the minimum be whatever the default is.

- Removes the hardcoding of +2 (for the number of elements we use in a
  sgl for cmd iu and rsp iu) and +1 (an additional entry to compensate
  for nvme's reduction of io size based on a possible partial page)
  logic in sg list initialization. In the case where the +1 logic is
  referenced in host and target io checks, use the values set in the
  transport template as that value was properly set.

There can certainly be more done in this area and it will be addressed
in combined host/target driver effort.

The current default for async hw receive queues is 1, which presents
issues under heavy load as number of queues influence the available
async receive buffer limits.

Raise the default to the either the current hw limit (16) or the number
of hw qs configured (io channel value).

Revise the attribute definition for mrq to better reflect what we do for
hw queues. E.g. 0 means default to optimal (# of cpus), non-zero
specifies a specific limit. Before this change, mrq=0 meant target mode
was disabled. As 0 now has a different meaning, rework the if tests to
use the better nvmet_support check.

Various oops including cpu LOCKUPs were seen.

For asynchronously received ius where the driver must assign exchange
resources, the resources were on a single get (free) list and put list
(finished, waiting to be put on get list). As all cpus are sharing the
lists, an interrupt for a receive frame may have to wait for all the
other cpus to place their done work onto the put list before it can
acquire the lock to pull from the list.

Fix by breaking the resource lists into per-cpu lists or at least more
than 1 list with cpu's sharing the lists). A cpu would allocate from the
free list for its own cpu, and put its done work on the its own put list
- avoiding the contention. As cpu load may vary, when empty, a cpu may
grab from another cpu, thereby changing resource distribution.  But
searching for a resource only occurs on 1 or a few cpus until a single
resource can be allocated. if the condition reoccurs, it starts looking
at a different cpu.

Currently, calls to nvmet_fc_rcv_fcp_req() always copied the
FC-NVME cmd iu to a temporary buffer before returning, allowing
the driver to immediately repost the buffer to the hardware.

To address timing conditions on queue element structures vs async
command reception, the nvmet_fc transport occasionally may need to
hold on to the command iu buffer for a short period. In these cases,
the nvmet_fc_rcv_fcp_req() will return a special return code
(-EOVERFLOW). In these cases, the LLDD must delay until the new
defer_rcv lldd callback is called before recycling the buffer back
to the hw.

Administrator intervention is currently required to get good numbers
when switching from running latency tests to IOPS tests.

The configured interrupt coalescing values will greatly effect the
results of these tests.  Currently, the driver has a single coalescing
value set by values of the module attribute.  This patch changes the
driver to support auto-configuration of the coalescing value based on
the total number of outstanding IOs and average number of CQEs processed
per interrupt for an EQ.  Values are checked every 5 seconds.

The driver defaults to the automatic selection. Automatic selection can
be disabled by the new lpfc_auto_imax module_parameter.

Older hardware can only change interrupt coalescing by mailbox

Add nvme initiator devloss support

The existing implementation was based on no devloss behavior in the
transport (e.g. immediate teardown) so code didn't properly handle
delayed nvme rport device unregister calls.  In addition, the driver was
not correctly cycling the rport port role for each
register-unregister-reregister process.

This patch does the following:

Rework the code to properly handle rport device unregister calls and
potential re-allocation of the remoteport structure if the port comes
back in under dev_loss_tmo.

Correct code that was incorrectly cycling the rport port role for each
register-unregister-reregister process.

Prep the code to enable calling the nvme_fc transport api to dynamically
update dev_loss_tmo when the scsi sysfs interface changes it.

Memset the rpinfo structure in the registration call to enforce "accept
nvme transport defaults" in the registration call.  Driver parameters do
influence the dev_loss_tmo transport setting dynamically.

Simplifies the register function: the driver was incorrectly searching
its local rport list to determine resume or new semantics, which is not
valid as the transport already handles this.  The rport was resumed if
the rport handed back matches the ndlp->nrport pointer.  Otherwise,
devloss fired and the ndlp's nrport is NULL.

Reviewing the result of what was just added for Kconfig, we made a poor
choice. It worked well for full kernel builds, but not so much for how
it would be deployed on a distro.

Here's the final result:
- lpfc will compile in NVME initiator and/or NVME target support based
  on whether the kernel has the corresponding subsystem support.
  Kconfig is not used to drive this specifically for lpfc.
- There is a module parameter, lpfc_enable_fc4_type, that indicates
  whether the ports will do FCP-only or FCP & NVME (NVME-only not yet
  possible due to dependency on fc transport). As FCP & NVME divvys up
  exchange resources, and given NVME will not be often initially, the

A previous change unilaterally removed the hba reset entry point
from the sli3 host template. This was done to allow tape devices
being used for back up from being removed. Why was this done ?
When there was non-responding device on the fabric, the error
escalation policy would escalate to the reset handler. When the
reset handler was called, it would reset the adapter, dropping
link, thus logging out and terminating all i/o's - on any target.
If there was a tape device on the same adapter that wasn't in
error, it would kill the tape i/o's, effectively killing the
tape device state.  With the reset point removed, the adapter
reset avoided the fabric logout, allowing the other devices to
continue to operate unaffected. A hack - yes. Hint: we really
need a transport I_T nexus reset callback added to the eh process
(in between the SCSI target reset and hba reset points), so a
fc logout could occur to the one bad target only and stop the error
escalation process.

This patch commonizes the approach so it can be used for sli3 and sli4
adapters, but mandates the admin, via module parameter, specifically
identify which adapters the resets are to be removed for. Additionally,
bus_reset, which sends Target Reset TMFs to all targets, is also removed
from the template as it too has the same effect as the adapter reset.

NVME Initiator: Base modifications

This patch adds base modifications for NVME initiator support.

The base modifications consist of:
- Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as
  rings as well) as implementation now widely varies between the two.
- Addition of configuration modes:
   SCSI initiator only; NVME initiator only; NVME target only; and
   SCSI and NVME initiator.
   The configuration mode drives overall adapter configuration,
   offloads enabled, and resource splits.
   NVME support is only available on SLI-4 devices and newer fw.
- Implements the following based on configuration mode:
  - Exchange resources are split by protocol; Obviously, if only
     1 mode, then no split occurs. Default is 50/50. module attribute
     allows tuning.
  - Pools and config parameters are separated per-protocol
  - Each protocol has it's own set of queues, but share interrupt
    vectors.
     SCSI:
       SLI3 devices have few queues and the original style of queue
         allocation remains.
       SLI4 devices piggy back on an "io-channel" concept that
         eventually needs to merge with scsi-mq/blk-mq support (it is
	 underway).  For now, the paradigm continues as it existed
	 prior. io channel allocates N msix and N WQs (N=4 default)
	 and either round robins or uses cpu # modulo N for scheduling.
	 A bunch of module parameters allow the configuration to be
	 tuned.
     NVME (initiator):
       Allocates an msix per cpu (or whatever pci_alloc_irq_vectors
         gets)
       Allocates a WQ per cpu, and maps the WQs to msix on a WQ #
         modulo msix vector count basis.
       Module parameters exist to cap/control the config if desired.
  - Each protocol has its own buffer and dma pools.
