Add trunking support to the driver. Trunking is found on more recent
asics. In general, trunking appears as a single "port" to the driver
and overall behavior doesn't differ. Link speed is reported as an
aggregate value, while link speed control is done on a per-physical
link basis with all links in the trunk symmetrical. Some commands
returning port information are updated to additionally provide
trunking information. And new ACQEs are generated to report physical
link events relative to the trunk.
This patch contains the following modifications:
- Added link speed settings of 128GB and 256GB.
- Added handling of trunk-related ACQEs, mainly logging and trapping
of physical link statuses.
- Added additional bsg interface to query trunk state by applications.
- Augment link_state sysfs attribtute to display trunk link status

When taking the board offline while performing i/o, unsafe locking errors
occurred and irq level isn't properly managed.
In lpfc_sli_hba_down, spin_lock_irqsave(&phba->hbalock, flags) does not
disable softirqs raised from timer expiry. It is possible that a softirq is
raised from the lpfc_els_retry_delay routine and recursively requests the same
phba->hbalock spinlock causing deadlock.
Address the deadlocks by creating a new port_list lock. The softirq behavior
can then be managed a level deeper into the calling sequences.

Driver only sends NVME PRLI to a device that also supports FCP. This resuls
in remote ports that don't have fc_remote_ports created for them. The driver
is clearing the nlp_fc4_type for a ndlp at the wrong time.
Fix by moving the nlp_fc4_type clearing to the discovery engine in the
DEVICE_RECOVERY state. Also ensure that rport registration is done for all
nlp_fc4_types.

Remote port disappearance/reappearances would cause a series of RSCN
events to be delivered to the driver. During the resulting GID_FT
handling, the driver clears the fc4 settings on the remote port, which
makes it skip registration. As such, the nvme associations eventually
fail and return io errors to the applications.
Correct by not clearng the nlp_fc4_types for all nodes in
lpfc_issue_gidft. Instead, when the GID_FT response is handled, clear
the nlp_fc4_types of FCP and NVME prior to evaluating the fc4_type
returned by the GID_FT response. This approach leaves "skipped" nodes
with their nlp_fc4_types intacted.

During target-side port faults, the driver would not recover all target
port logins. This resulted in a loss of nvme device discovery.
The driver is coded to wait for all GID_FT requests to complete before
restarting discovery. A fault is seen where the outstanding GIT_FT
counts are not properly decremented, thus discovery would never
start. Another fault was found in the clearing of the gidft_inp counter
that would be skipped in this condition. And a third fault found with
lpfc_nvme_register_port that would remove a reverence on the ndlp which
then allows a node swap on a port address change to prematurely remove
the reference and release the ndlp.
The following changes are made:
- Correct the decrementing of the outstanding GID_FT counters.
- In RSCN handling, no longer zero the counter before calling to issue
another GID_FT.
- No longer remove the reference on the dlp when the ndlp->nrport value
is not yet null.

When a port is configured for NVME and SCSI Initiator support and it probes
a target supporting both SCSI and NVME, NVME devices are discovered, but
SCSI devices are not.
The nlp_fc4_type for all NPorts should be cleared on Link Up or just before
GID_FTs get issued, as opposed to just during GID_FT cmpl. RSCN activity as
well as Link Up can trigger GID_FT. One GID_FT may complete before the next
one is issued.
Fix by clearng nlp_fc4_type on link up and just before both GID_FTs are

When enabled for both SCSI and NVME support, and connected pt2pt to a
SCSI only target, the driver nodelist entry for the remote port is left
in PRLI_ISSUE state and no SCSI LUNs are discovered. Works fine if only
configured for SCSI support.
Error was due to some of the prli points still reflecting the need to
send only 1 PRLI. On a lot of fabric configs, targets were NVME only,
which meant the fabric-reported protocol attributes were only telling
the driver one protocol or the other. Thus things worked fine. With
pt2pt, the driver must send a PRLI for both protocols as there are no
hints on what the target supports. Thus pt2pt targets were hitting the
multiple PRLI issues.
Complete the dual PRLI support. Track explicitly whether scsi (fcp) or
nvme prli's have been sent. Accurately track protocol support detected
on each node as reported by the fabric or probed by PRLI traffic.

NVMET didn't have any RSCN handling at all and
would not execute implicit LOGO when receiving a PLOGI
from an rport that NVMET had in state UNMAPPED.
Clean up the logic in lpfc_nlp_state_cleanup for
initiators (FCP and NVME). NVMET should not respond to
RSCN including allocating new ndlps so this code was
conditionalized when nvmet_support is true. The check
for NLP_RCV_PLOGI in lpfc_setup_disc_node was moved
below the check for nvmet_support to allow the NVMET
to recover initiator nodes correctly. The implicit
logo was introduced with lpfc_rcv_plogi when NVMET gets
a PLOGI on an ndlp in UNMAPPED state. The RSCN handling
was modified to not respond to an RSCN in NVMET. Instead
NVMET sends a GID_FT and determines if an NVMEP_INITIATOR
it has is UNMAPPED but no longer in the zone membership.
