This patch will do code optmization for task management functions.
Below are key changes:
1. Remove reset_device hook as it was not being used and driver was
setting this to NULL.
2. Create wrapper functions for task abort and target reset and inside
these functions adapter specific calls be made. e.g. fusion adapters
support task abort and target reset so task abort and target reset
should be issued to fusion adapters only and for MFI adapters, print
a message saying feature not supported.

In OCR path, before calling chip reset calls function
megasas_wait_for_outstanding_fusion to check reason for OCR. In case of
firmware FAULT initiated OCR and DCMD timeout initiated timeout, driver
will clear any outstanding reply (yet to be processed by driver) in
reply queues before going for chip reset. This code is added to handle a
scenario when IO timeout initiated adapter reset and management
application initiated adapter reset (by sending command to FAULT
firmware) happens simultaneously since adapter reset function is
safe-guarded by reset_mutex so only thread will be doing controller
reset. Consider IO timeout thread gets mutex and proceeds with adapter
reset process after disabling interrupts and by the time management
application has fired command to firmware to do adapter reset and the
same command is completed by firmware but since interrupts are disabled,
driver will not get completion and the same command will be in
outstanding/pending commands list of driver and refires same command
from IO timeout thread after chip reset which will again FAULT firmware
and eventually causes kill adapter.

When KDUMP is triggered the driver first talks to the firmware in INTX
mode, but the adapter firmware is still in MSIX mode. Therefore the first
driver command hangs since the driver is waiting for an INTX response and
firmware gives a MSIX response. If when the OS is installed on a RAID
drive created by the adapter KDUMP will hang since the driver does not
receive a response in sync mode.

Typically under error conditions, it is possible for aac_command_thread()
to miss the wakeup from kthread_stop() and go back to sleep, causing it
to hang aac_shutdown.
In the observed scenario, the adapter is not functioning correctly and so
aac_fib_send() never completes (or time-outs depending on how it was
called). Shortly after aac_command_thread() starts it performs
aac_fib_send(SendHostTime) which hangs. When aac_probe_one
/aac_get_adapter_info send time outs, kthread_stop is called which breaks
the command thread out of it's hang.
The code will still go back to sleep in schedule_timeout() without
checking kthread_should_stop() so it causes aac_probe_one to hang until
the schedule_timeout() which is 30 minutes.

On loosely ordered memory systems (PPC for example), the WQE elements
were being updated in memory, but not necessarily flushed before the
separate doorbell was written to hw which would cause hw to dma the
WQE element. Thus, the hardware occasionally received partially
updated WQE data.
Add the memory barrier after updating the WQE memory.

The BUG_ON() recently introduced in lpfc_sli_ringtxcmpl_put() is hit in
the lpfc_els_abort() > lpfc_sli_issue_abort_iotag() >
lpfc_sli_abort_iotag_issue() function path [similar names], due to
'piocb->vport == NULL':
BUG_ON(!piocb || !piocb->vport);
This happens because lpfc_sli_abort_iotag_issue() doesn't set the
'abtsiocbp->vport' pointer -- but this is not the problem.
Previously, lpfc_sli_ringtxcmpl_put() accessed 'piocb->vport' only if
'piocb->iocb.ulpCommand' is neither CMD_ABORT_XRI_CN nor
CMD_CLOSE_XRI_CN, which are the only possible values for
lpfc_sli_abort_iotag_issue():
So, this function path would not have hit this possible NULL pointer
dereference before.
In order to fix this regression, move the second part of the BUG_ON()
check prior to the pointer dereference that it does check for.
For reference, this is the stack trace observed. The problem happened
because an unsolicited event was received - a PLOGI was received after
our PLOGI was issued but not yet complete, so the discovery state
machine goes on to sw-abort our PLOGI.

A recent bugfix introduced a harmless warning in the lpfc driver:
drivers/scsi/lpfc/lpfc_init.c: In function 'lpfc_write_firmware':
drivers/scsi/lpfc/lpfc_logmsg.h:56:45: error: format '%ld' expects argument of type 'long int', but argument 9 has type 'size_t {aka const unsigned int}' [-Werror=format=]
'size_t' is always the same width as 'long' in the kernel, but the
compiler doesn't know that. The %z modifier is what the standard expects
to be used here, and this shuts up the warning.

drivers/scsi/lpfc/lpfc_attr.c:3064:1930: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
The code works as intended, but it would be nice to shut up the warning
so we don't clutter up build logs with this. Using a separate inline
function for it makes it clear to the compiler that the comparison is
necessary in the caller but still lets it do the constant-folding.

Commit 4cace675d687 ("bnx2x: Alloc 4k fragment for each rx ring buffer
element") added extra put_page() and get_page() calls on arches where
PAGE_SIZE=4K like x86
Reorder things to avoid this overhead.

Only the 578xx adapters are capable of configuring UDP ports for
the purpose of tunnelling - doing the same on 577xx might lead to
a firmware assertion.
We're already not claiming support for any related feature for such
devices, but we also need to prevent the configuration of the UDP
ports to the device in this case.

The msix_entries memory can be freed by a previous suspend or
remove, so don't crash on close when it isn't there. Also only
clear the interrupts when the interface is up, because there
aren't any when it is not up.

For some Tx paths (e.g., tpacket_snd()), ixgbe_atr may be
passed down an sk_buff that has the network and transport
header in the paged data, so it needs to make sure these
headers are available in the headlen bytes to calculate the
l4_proto.
This patch expect that network and transport headers are
already available in the non-paged header dat. The assumption
is that the caller has set this up if l4_proto based Tx
steering is desired.
