Fixes:
1. Initialize vlan_id to LPFC_FCOE_NULL_VID.
2. Initialize vlan_id to LPFC_FCOE_NULL_VID.
3. prg->dist is a 2 bit field. Its value can only be between 0-3.
Remove redundent check 'if (prg->dist < 4)'.
4. Fix inconsistent indenting. Moved logic into helper function
lpfc_fill_vpd().
5. Define 'eqhdl->irq' as int value as pci_irq_vector() returns int.
Also, check for return value of pci_irq_vector() and log message in
case of failure.
6. Initialize 'ext_cnt' to 0.
7. Initialize 'ext_size' to 0.
8. Use alloc_percpu_gfp() with GFP_ATOMIC flag.
9. 'rc' was not updated when dma_pool_create() fails. Update 'rc =
-ENOMEM' when dma_pool_create() fails before calling goto statement.
10. Add check for 'phba->pport' in lpfc_cpuhp_remove().
11. Initialize 'hash_value' to NULL, same like 'aug_chal' variable.

Removed the lpfc_fdmi_attr_entry and lpfc_fdmi_attr_def structures that had
a union causing unintentional zero padding, which required the usage of
__packed. They are replaced with explicit lpfc_fdmi_attr_u32,
lpfc_fdmi_attr_wwn, lpfc_fdmi_attr_fc4types, and lpfc_fdmi_attr_string
structure defines instead of living in a union. This rids of ambiguous
compiler zero padding, and entailed cleaning up bitwise endian
declarations.
As such, all FDMI attribute registration routines are replaced with generic
void *arg and handlers for each of the newly defined attribute structure
types.

On a PCI hotplug capable system, it is possible for scsi_device_put() to
happen after lpfc_pci_remove_one() is called. As a result, the
sdev->host->hostt->module dereference is for a previously freed memory
location because the phba structure containing the hostt template was
already freed when lpfc_pci_remove_one() returned.
Since the lpfc module is still loaded during power slot disable, all
scsi_host_templates should be declared as part of the global data segment
instead of inside the heap allocated phba structure. This way the
sdev->host->hostt memory area is always valid as long as the module is
loaded regardless if PCI hotplug dynamically allocates or frees phba
structures.
Move all scsi_host_templates in the phba structure to global variables.
Create a small helper routine to determine appropriate sg_tablesize during
shost allocation.

When a target makes the mistake of registering a FC4 type with the fabric,
but then rejects a PRLI of that type, the lpfc driver incorrectly retries
the PRLI causing multiple registrations with the transport. The driver
needs to detect the reject reason data and stop any retry.
Rework the PRLI reject scenarios.

Sometimes VMID targets are not getting rediscovered after a port reset.
The iocb is not freed in lpfc_cmpl_ct_cmd_vmid(), which is the completion
function for the appid CT commands. So after a port reset, the count of
sges is less than the expected count of 250. This causes post reset
operation logic to fail and keep the port offline.
Fix by freeing the iocb and kref put for the lpfc_cmpl_ct_cmd_vmid() early
return cases.

When a FLOGI is received before we have issued our FLOGI, the ACC response
to the received FLOGI is issued with SID 2 instead of the expected fabric
controller SID. Certain target vendors ignore the malformed ACC with SID 2
and wait for a properly filled ACC with a fabric controller SID.
The lpfc_sli_prep_wqe() routine depends on the FC_PT2PT flag to fill in the
fabric controller SID when in PT2PT mode, but due to a previous commit the
flag was getting cleared. Fix by adding a check for the defer_flogi_acc
flag to know whether or not to clear the FC_PT2PT flag on link up.

The if statment check (prli_fc4_req & PRLI_NVME_TYPE) evaluates to true
when receiving a PRLI request for bogus FC4 type codes that happen to have
the 3rd or 5th bit set because PRLI_NVME_TYPE is 0x28. This leads to
sending a PRLI_NVME_ACC even for bogus FC4 type codes.
Change the bitwise & check to an exact == type code check to ensure we send
PRLI_NVME_ACC only for NVME type coded PRLI requests.

On arm64, atomic_xchg only works on 8-bit byte fields. Thus, the macro
usage of LPFC_RXMONITOR_TABLE_IN_USE can be unintentionally truncated
leading to all logic involving the LPFC_RXMONITOR_TABLE_IN_USE macro to not

During a stress offline/online test in PT2PT topology, target rediscovery
can fail with a specific target vendor array.
When the HBA transitions to online mode it is possible to receive an
unsolicited FLOGI before processing the Link Up event. The received FLOGI
will set the defer_flogi_acc_flag, which instructs the driver to wait until
it transmits its own FLOGI before ACKing the received FLOGI. In this
failure scenario, the link up processing clears the set
defer_flogi_acc_flag before we have sent out the FLOGI. As the target has
the higher WWPN and is responsible for sending the PLOGI, the target is
stuck waiting for its FLOGI_ACC that the driver will never send.
Remove the clear of defer_flogi_acc_flag from Link Up event processing. In
this stress test case, the defer_flogi_acc_flag is cleared during the Link
Down event processing anyways.

The RSCN_MEMENTO logic was to workaround a target that does not register
both FCP and NVMe FC4 types at the same time. This caused the
configuration to not produce a second RSCN for the NVMe FC4 type
registration in a timely manner. The intention of the RSCN_MEMENTO flag
was to always signal to try NVMe PRLI.
However, there are other FCP-only target arrays in correctly behaved
configurations that reject the NVMe PRLI followed by a LOGO leading to
never rediscovering the target after an issue_lip (as LOGO causes a repeat
of PLOGI/PRLIs).
Revert the RSCN_MEMENTO patch as it is causing correctly behaved configs to
fail while it exists only to succeed on a misbehaved config.

neglected to swap the nlp_fc4_type in the ndlp passed to
lpfc_plogi_confirm_nport causing a failure to recover the NVMe PLOGI/PRLI
and ultimately the NVMe paths.

The code didn't initialize the total_data_placed word, inheriting stack

After issuing a LIP, a specific target vendor does not ACC the FLOGI that
lpfc sends. However, it does send its own FLOGI that lpfc ACCs. The
target then establishes the port IDs by sending a PLOGI. lpfc PLOGI_ACCs
and starts the RPI registration for DID 0x000001. The target then sends a
LOGO to the fabric DID. lpfc is currently treating the LOGO from the
fabric DID as a link down and cleans up all the ndlps. The ndlp for DID
0x000001 is put back into NPR and discovery stops, leaving the port in
stuck in bypassed mode.
Change lpfc behavior such that if a LOGO is received for the fabric DID in
PT2PT topology skip the lpfc_linkdown_port() routine and just move the
fabric DID back to NPR.

A use-after-free crash can occur after an ELS LOGO is aborted.
Specifically, a nodelist structure is freed and then
ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the
discovery state machine is mistakenly called a second time with
NLP_EVT_DEVICE_RM argument.
Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a
nodelist structure.

Refactoring and consolidation of abort paths:
- lpfc_sli4_abort_fcp_cmpl() and lpfc_sli_abort_fcp_cmpl() are combined
into a single generic lpfc_sli_abort_fcp_cmpl() routine. Thus, remove
extraneous lpfc_sli4_abort_fcp_cmpl() prototype declaration.
- lpfc_nvme_abort_fcreq_cmpl() abort completion routine is called with a
mismatched argument type. This may result in misleading log message
content. Update to the correct argument type of lpfc_iocbq instead of
lpfc_wcqe_complete. The lpfc_wcqe_complete should be derived from the
lpfc_iocbq structure.
