This patch adds the ability to read firmware logs from the adapter. The driver
registers a buffer with the adapter that is then written to by the adapter.
The adapter posts CQEs to indicate content updates in the buffer. While the
adapter is writing to the buffer in a circular fashion, an application will
poll the driver to read the next amount of log data from the buffer.
Driver log buffer size is configurable via the ras_fwlog_buffsize sysfs
attribute. Verbosity to be used by firmware when logging to host memory is
controlled through the ras_fwlog_level attribute. The ras_fwlog_func
attribute enables or disables loggy by firmware.

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

On io completion, the driver is taking an adapter wide lock and nulling the
scsi command back pointer. The nulling of the back pointer is to signify the
io was completed and the scsi_done() routine was called. However, the routine
makes no check to see if the abort routine had done the same thing and
possibly nulled the pointer. Thus it may doubly-complete the io.
Make the following mods:
- Check to make sure forward progress (call scsi_done()) only happens if the
command pointer was non-null.
- As the taking of the lock, which is adapter wide, is very costly on a system
under load, null the pointer using an xchg operation rather than under lock.

The driver allocates a sg list per io struture based on a fixed maximum
size. When it registers with the protocol transports and indicates the max sg
list size it supports, the driver manipulates the fixed value to report a
lesser amount so that it has reserved space for sg elements that are used for
DIF.
The driver initialization path sets the cfg_sg_seg_cnt field to the
manipulated value for scsi. NVME initialization ran afterward and capped it's
maximum by the manipulated value for SCSI. This erroneously made NVME report
the SCSI-reduce-for-DIF value that reduced the max io size for nvme and wasted
sg elements.
Rework the driver so that cfg_sg_seg_cnt becomes the overall maximum size and
allow the max size to be tunable. A separate (new) scsi sg count is then
setup with the scsi-modified reduced value. NVME then initializes based off
the overall maximum.

Enabling list_debug showed the drivers txcmplq was suffering list
corruption. The systems will eventually crash because the iocb free list
gets crossed linked with the prings txcmplq. Most systems will run for a
while after the corruption, but will eventually crash when a scsi eh reset
occurs and the txcmplq is attempted to be flushed. The flush gets stuck in
an endless loop.
The problem is the abort handler does not hold the sli4 ring lock while
validating the IO so the IO could complete while the driver is still
preping the abort. The erroneously generated abort, when it completes, has
pointers to the original IO that has already completed, and the IO
manipulation (for the second time) corrupts the list.
