After seeing some interoperability issues with ADISC, it was determined the
ELS definitions in lpfc were using types that allowed the compiler to add
pad to the structure, causing the structure to no longer be per spec. The
offending structures are ADISC, FAN, and RNID.
This patch implements the simple fix of eliminating the pad by forcing the
compiler to pack the structure. Care was taken to ensure field accesses
won't be by operations that would hit a bad field alignment.
The better solution would be to convert to the uapi fc header definitions,
but the number of changes required to do is rather intrusive so this course
of action was deferred.

In some link initialization sequences, the fw generates an erroneous FLOGI
payload to the driver without an intervening link bounce. The driver, when
it sees a 2nd FLOGI without an intervening link bounce, automatically
performs a link bounce. In this, the link bounce causes the situate to
repeat and in a nasty loop of link bounces.
Resolve the issue by validating the FLOGI payload. The erroneous FLOGI will
contain VVL signatures that are not normal. When the driver sees these, it
will simply reject the flogi rather than bouncing the link. The reject is
consumed within the firmware.

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.
I apologize for the size of the patch.
