[PATCH 01/20] scsi: lpfc: remove redundant assignment of sgel

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

From: Colin Ian King <colin.king@canonical.com>

In the NVMET_FCOP_RSP case, sgel is assigned but never used and
hence is redundant and can be removed.

[PATCH 03/20] scsi: lpfc: don't dereference dma_buf->iocbq before null check

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

From: Colin Ian King <colin.king@canonical.com>

dma_buf->iocbq is being dereferenced immediately before it is
being null checked, so we have a potential null pointer dereference
bug.  Fix this by only dereferencing it only once we have passed
a null check on the pointer.

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

From: Colin Ian King <colin.king@canonical.com>

In the case where sglq is null, the current code just returns without
unlocking the spinlock sql_list_lock. Fix this by breaking out of the
while loop and the exit path will then unlock and return NULL as was
the original intention.

From: James Smart <jsmart2021@gmail.com>

NVME LS requests and responses had wrong R_CTL values.
Use the FC4 ELS Request and Response defines (defines badly
named, they are FC4 LS's) instead of the base ELS values.

[PATCH 10/20] lpfc: add NVME exchange aborts

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

previous code did little more than log a message.

This patch adds abort path support, modeled after the SCSI code paths.
Currently addresses only the initiator path. Target path under
development, but stubbed out.

[PATCH 11/20] lpfc: Fix eh_deadline setting for sli3 adapters.

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

A previous change unilaterally removed the hba reset entry point
from the sli3 host template. This was done to allow tape devices
being used for back up from being removed. Why was this done ?
When there was non-responding device on the fabric, the error
escalation policy would escalate to the reset handler. When the
reset handler was called, it would reset the adapter, dropping
link, thus logging out and terminating all i/o's - on any target.
If there was a tape device on the same adapter that wasn't in
error, it would kill the tape i/o's, effectively killing the
tape device state.  With the reset point removed, the adapter
reset avoided the fabric logout, allowing the other devices to
continue to operate unaffected. A hack - yes. Hint: we really
need a transport I_T nexus reset callback added to the eh process
(in between the SCSI target reset and hba reset points), so a
fc logout could occur to the one bad target only and stop the error
escalation process.

This patch commonizes the approach so it can be used for sli3 and sli4
adapters, but mandates the admin, via module parameter, specifically
identify which adapters the resets are to be removed for. Additionally,
bus_reset, which sends Target Reset TMFs to all targets, is also removed
from the template as it too has the same effect as the adapter reset.

[PATCH 12/20] lpfc: add transport eh_timed_out reference

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

Christoph's prior patch missed the template for the sli3 adapters,
which is now the "no host reset" template. Add the transport
eh_timed_out handler to the no host reset template

[PATCH 13/20] lpfc: Rework lpfc Kconfig for NVME options

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

Reworked Kconfig so that lfpc only requires the scsi stack.
NVME Initiator and NVME Target support can be enabled if
the other NVMe subsystems have been enabled.

[PATCH 14/20] lpfc: Rename LPFC_MAX_EQ_DELAY to LPFC_MAX_EQ_DELAY_EQID_CNT

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

Without apriori understanding of what the define is, the name gives
a very different impression of what it is (a max delay value
for an EQ).  Rename the define so it reflects what it is: the number
of EQ IDs that can be set in one instance of the MODIFY_EQ_DELAY
mbx command.

[PATCH 17/20] lpfc: correct rdp diag portnames

[jsmart2021]

From: James Smart <jsmart2021@gmail.com>

NVME merge reverted diag port names to the physical port.
They should be the vport.
