When debugging a recent discovery customer problem it was very hard to tell
what was happening with the existing discovery log messages. To fully debug
the issue additional log messages were necessary.
Add or extend log messages so that sufficient information is present for
debugging.

In the past, the lpe32000 models, based their main support being for 32G,
and as FC-AL is not supported in the FC standards past 8G, did not support
FC-AL operation.
This patch adds private-loop FC-AL support for the LPE32000 adapters
when a link is 8G or below. To avoid conditions where link rate may
change, which would cause non-connectivity to the AL device, FC-AL
mode must become a persistent setting and the link kept at a speed
supporting FC-AL.
The patch:
- Adds a pls attribute indicating whether the adapter properly supports
FC-AL.
- Adds support for the adapter to indicate that topology should be fixed
and the topology types to be configured.
- Adds a pt attribute to report the persistent topology if present.

Add two new macros to aid in message logging:
Both macros print a message if the corresponding lpfc verbosity setting is
set or the kernel log level is WARNING or more critical.
One macro is for use with a phba structure, the other with a vport
structure.

Currently, the FW logging facility is a load/boot time parameter which
requires the driver to be unloaded/reloaded or the system rebooted in order
to change its configuration.
Convert the logging facility to allow dynamic enablement and configuration.
Specifically:
- Convert the feature so that it can be enabled dynamically via an
attribute. Additionally, the size of the buffer can be configured
dynamically.
- Add locks around states that now may be changing.
- Tie the feature into debugfs so that the logs can be read at any time.

The existing "auto eq delay" mechanism was sometimes skipping over an EQ,
not ramping the coalescing down under light load fast enough, and in other
cases never kicked in as cpu sharing by multiple vectors didn't quite add
up right.
Tweak the interrupt mechanism such that:
- Add a flag to the EQ to force checking for colaescing values when being
serviced in the interrupt handler. The flag will be set by any CQ bound
to the EQ whenever the number of CQ elements process in a single scan
meets or exceeds the hardware queue notify level. E.g. there's a
significant number of completions happening.
- In the heartbeat work item that checks coalescing:
- Replace the structure that was counting the number of EQs that
interrupted on a single cpu with a new structure that looks at the EQ
to see whether EQ currently has a coalescing value (thus it should be
re-evaluate) or was marked by the new flag indicating heavy
completions.
- When a cpu, which may be servicing multiple vectors, had at least 1 EQ
that should be checked, a new coalescing delay is calculated based on
the number of interrupts that occurred on the cpu.
- The new coalescing value is then applied to the EQs that had
interrupted on the cpu.

Lower IOps performance with write operations. Perf tool shows lock
contention in dma_pool_alloc and dma_pool_free related to the
txrdy_payload_pool.
The allocations are for dma buffers for XFER_RDY's, which actually are not
needed for the FCP_TRECEIVE command as the command contents are used by the
adapter to generate the IU.
Remove the allocations and the associated buffer pool. Rather than leaving
NULLs in buffer pointer locations, set command and sgl to indicate skipped
SGLE indexes.

In lpfc_abort_handler, the lock acquire order is hbalock (irqsave),
buf_lock (irq) and ring_lock (irq). The issue is that in two places the
locks are released out of order - the buf_lock and the hbalock - resulting
in the cpu preemption/lock flags getting restored out of order and
deadlocking the cpu.
Fix the unlock order by fully releasing the hbalocks as well.

In cases where I/O may be aborted, such as driver unload or link bounces,
the system will crash based on a bad ndlp pointer.
Example:
RIP: 0010:lpfc_sli4_abts_err_handler+0x15/0x140 [lpfc]
...
lpfc_sli4_io_xri_aborted+0x20d/0x270 [lpfc]
lpfc_sli4_sp_handle_abort_xri_wcqe.isra.54+0x84/0x170 [lpfc]
lpfc_sli4_fp_handle_cqe+0xc2/0x480 [lpfc]
__lpfc_sli4_process_cq+0xc6/0x230 [lpfc]
__lpfc_sli4_hba_process_cq+0x29/0xc0 [lpfc]
process_one_work+0x14c/0x390
Crash was caused by a bad ndlp address passed to I/O indicated by the XRI
aborted CQE. The address was not NULL so the routine deferenced the ndlp
ptr. The bad ndlp also caused the lpfc_sli4_io_xri_aborted to call an
erroneous io handler. Root cause for the bad ndlp was an lpfc_ncmd that
was aborted, put on the abort_io list, completed, taken off the abort_io
list, sent to lpfc_release_nvme_buf where it was put back on the abort_io
list because the lpfc_ncmd->flags setting LPFC_SBUF_XBUSY was not cleared
on the final completion.
Rework the exchange busy handling to ensure the flags are properly set for
both scsi and nvme.

When operating in private loop mode, PLOGI exchanges are racing and the
driver tries to abort it's PLOGI. But the PLOGI abort ends up terminating
the login with the other end causing the other end to abort its PLOGI as
well. Discovery never fully completes.
Fix by disabling the PLOGI abort when private loop and letting the state
machine play out.

...
For the Algorithm, as stated in [RFC1994], one value is required to
be implemented:
5 (CHAP with MD5)
LIO currently checks for this value by only comparing a single byte in
the tokenized Algorithm string, which means that any value starting with
a '5' (e.g. "55") is interpreted as "CHAP with MD5". Fix this by
comparing the entire tokenized string.

Add error handling logic to ELS Passthrough relating to NVME devices.
Current code does not parse error code to take proper recovery action,
instead it re-logins with the same login parameters that encountered the
error. Ex: nport handle collision.

Some storage arrays advertise FCP LUNs and NVMe namespaces behind the same
WWN. The driver now offers a user option by way of NVRAM parameter to
allow users to choose, on a per port basis, the kind of FC-4 type they
would like to prioritize for login.
