Miscellaneous Fixes and Corrections
- Remove the memset in the lpfc_sli4_remove_rpi_hdrs call.
- Correct swapping of SGE word 2 relative to offset value
- Reorganize CQ and EQ usage to comply with SLI4 Specification.
- Expand the driver to check the rn bit. Only detect an error if the error bit
is set and the RN bit is NOT set.
- If mailbox completion code is not success AND the mailbox status is success,
then and only then will the driver overwrite the mailbox status.
- When driver initializing device, if the device is on a PCIe bus, set
PCI's "needs fundamental reset" bit so that EEH uses fundamental reset
instead of hot reset for recovery.
- Prevent driver from using new WWN when changed in firmware (until driver
reload)
- When HBA reports maximum SGE size > 0xffffffff (infinite), override
with 0x80000000.
- Fixed potential missed SLI4 device initialization failure conditions.
- Added 100ms delay before driver action following IF_TYPE_2 function reset.
- Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node.
- Add a check for the CVL received flag in the fcf inuse routine to avoid
unregistering the fcf if Devloss fires before Delay discover timer fires.

Commit 56dd2c06 "libsas: Don't issue commands to devices that have been
hot-removed" edited Darrick's original patch to remove setting 'gone' in
the sas_deform_port() path because that prevented scsi sync cache
commands from being issued when the driver was unloaded. However, this
allows true device gone notifications (as signaled port phy events) to
trigger sync cache commands to devices that are known to be unreachable.
Teach libsas which sas_deform_port() invocations are likely device gone
events.

In error recovery, most scsi error recovery stages will send a TUR command
for every bad command when a driver's error handler reports success. When
several bad commands to the same device, this results in a device
being probed multiple times.
This becomes very problematic if the device or connection is in a state
where the device still doesn't respond to commands even after a recovery
function returns success. The error handler must wait for the test
commands to time out. The time waiting for the redundant commands can
drastically lengthen error recovery.
This patch alters the scsi mid-layer's error routines to send test commands
once per device instead of once per bad command. This can drastically
lower error recovery time.

Some kernel transport drivers unconditionally disable
retrieval of the Caching mode page. One such for example is
the BBB/CBI transport over USB. Such a restraint is too
harsh as some devices do support the Caching mode
page. Unconditionally enabling the retrieval of this mode
page over those transports at their transport code level may
result in some devices failing and becoming unusable.
This patch implements a method of retrieving the Caching
mode page without unconditionally enabling it in the
transports which unconditionally disable it. The idea is to
ask for all supported pages, page code 0x3F, and then search
for the Caching mode page in the mode parameter data
returned. The sd driver already asks for all the mode pages
supported by the attached device by setting the page code to
0x3F in order to find out if the media is write protected by
reading the WP bit in the Device Specific Parameter
field. It then attempts to retrieve only the Caching mode
page by setting the page code to 8 and actually attempting
to retrieve it if and only if the transport allows it.
The method implemented here is that if the transport doesn't
allow retrieval of the Caching mode page and the device is
not RBC, then we ask for all pages supported by setting the
page code to 0x3F (similarly to how the WP bit is retrieved
above), and then we search for the Caching mode page in the
mode parameter data returned.
With this patch, devices over SATA, report this (no change):

assumption about the device's cache being write-through:

And "dumb" devices over BBB, are correctly shown not to

Modified the event coalescing code for iSCSI offload to combat both
corner cases and optimize performance as follows:
1. Added mechanism to loop back a second time to process any leftover
CQEs that was generated by the hardware during the time the driver is
busy processing previous CQEs in the bh. This not only helps the
performance but also fixes the corner case when no more CQEs are being
generated in the pipeline; so those leftover CQEs will get a a chance
to be processed.
2. Added ARM_CQE_FP to distinguish between fast path arming versus
slow path arming. This change will guarantee that the CQEs will
always get a chance to be re-armed during fast path completions.
3. Removed the inline event coalescing division for perf optimization.
Also fixed a division-by-zero error when the event_coal_div module
param was set to 0.
4. Changed the default SQ WQEs size from 256 to 128 to match chip
default.
5. Changed the cmd_per_lun from 32 to 24.

The number of chip's internal command cell, which is use to generate

This, in turn, will create a problem where the chip's transmit pipe
will erroneously reuse an old command cell that is no longer valid.
The fix is to correctly initialize the chip's command cell upon setup.

If the driver is getting flooded with interrupts, there's a possibility
that the interrupt service routine could falsely detect a stuck interrupt
condition and reset the adapter.
This patch changes the logic such that the routine will loop back into
the command processing code one more time after detecting the stuck
interrupt signature. If there are no commands to process after that pass,
and the interrupt is still not cleared, then the driver will print the
"Error clearing HRRQ" message and reset the adapter.

libfcoe's interface consists of create, destroy, enable,
disable and create_vn2vn. These are currently module
paramaters added durring the module initialization. A
concern arose that the module parameters were being added
with write permissions before the module had completed
initialization. The following code was added to each
sysfs store file.
* Make sure the module has been initialized, and is not about to be
* removed. Module parameter sysfs files are writable before the
* module_init function is called and after module_exit.
*/
if (THIS_MODULE->state != MODULE_STATE_LIVE)
goto out_nodev;
This check was called out as unhelpful as the module can
go dead at any time and therefore its state isn't a reliable
thing to look at as a sign of stability and initialization
completion. Also, that functional interfaces like these
should be added after module initialization.
This patch removes the unnecessary checks and hopes to
disprove the concern about initialization ordering.
Recent fcoe transport rework changes now require fcoe
transports to register with libfcoe before any operation
can take place. libfcoe may access some static variables
but nothing that could cause a problem. Once a fcoe transport
is registered, libfcoe is usable and any interface calls will
be functional.
