The issue to be fixed in this commit is when libfc found it received a
invalid FLOGI response from FC switch, it would return without freeing the
fc frame, which is just the skb data. This would cause memory leak if FC
switch keeps sending invalid FLOGI responses.
This fix is just to make it execute `fc_frame_free(fp)` before returning
from function `fc_lport_flogi_resp`.

Pull SCSI updates from James Bottomley:
"This update includes the usual round of major driver updates (ncr5380,
lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).
There's also an assortment of minor fixes, mostly in error legs or
other not very user visible stuff. The major change is the
pci_alloc_irq_vectors replacement for the old pci_msix_.. calls; this
effectively makes IRQ mapping generic for the drivers and allows
blk_mq to use the information"

The list of attached 'rdata' remote port structures is RCU
protected, so there is no need to take the 'disc_mutex' when

Rather we should be using rcu_read_lock() and kref_get_unless_zero()

We need, however, take the disc_mutex when deleting an entry;
otherwise we risk clashes with list_add.

The fc_get_host_stats() function contains a complex conversion from
jiffies to timespec to seconds. As we try to get rid of uses of struct
timespec, we can clean this up and replace it with a simpler
computation.
Simply dividing the difference in jiffies by HZ is not only much more
efficient, it also avoids a problem that causes the
seconds_since_last_reset value to be incorrect if jiffies has overrun
since the 'boot_time' value was recorded.

Originally libfc would just be initializing the refcount to '1', and
using the disc_mutex to synchronize if and when the final put should be
happening. This has a race condition as the mutex might be delayed,
causing other threads to access an invalid structure. This patch
updates the rport reference counting to increase the reference every
time 'rport_lookup' is called, and decreases the reference
correspondingly. This removes the need to hold 'disc_mutex' when
removing the structure, and avoids the above race condition.

sec 4.6.1 "If the Requesting_CT does not receive a Response
CT_IU from the Responding_CT within three times R_A_TOV,
it shall consider this to be a protocol error."
This means added four new states with management server
could add significant delay with multiple retries
on default 12 second timeout(3 * R_A_TOV), so instead
just skip these states on very first timeout on any of
these states to not stuck with states for such longer

isci update for 3.5
1/ Rework remote-node-context (RNC) handling for proper management of
the silicon state machine in error handling and hot-plug conditions.
Further details below, suffice to say if the RNC is mismanaged the
silicon state machines may lock up.
2/ Refactor the initialization code to be reused for suspend/resume support
3/ Miscellaneous bug fixes to address discovery issues and hardware
compatibility.
RNC rework details from Jeff Skirvin:
In the controller, devices as they appear on a SAS domain (or
direct-attached SATA devices) are represented by memory structures known
as "Remote Node Contexts" (RNCs). These structures are transferred from
main memory to the controller using a set of register commands; these
commands include setting up the context ("posting"), removing the
context ("invalidating"), and commands to control the scheduling of
commands and connections to that remote device ("suspensions" and
"resumptions"). There is a similar path to control RNC scheduling from
the protocol engine, which interprets the results of command and data
transmission and reception.
In general, the controller chooses among non-suspended RNCs to find one
that has work requiring scheduling the transmission of command and data
frames to a target. Likewise, when a target tries to return data back
to the initiator, the state of the RNC is used by the controller to
determine how to treat the incoming request. As an example, if the RNC
is in the state "TX/RX Suspended", incoming SSP connection requests from
the target will be rejected by the controller hardware. When an RNC is
"TX Suspended", it will not be selected by the controller hardware to
start outgoing command or data operations (with certain priority-based
exceptions).
As mentioned above, there are two sources for management of the RNC
states: commands from driver software, and the result of transmission
and reception conditions of commands and data signaled by the controller
hardware. As an example of the latter, if an outgoing SSP command ends
with a OPEN_REJECT(BAD_DESTINATION) status, the RNC state will
transition to the "TX Suspended" state, and this is signaled by the
controller hardware in the status to the completion of the pending
command as well as signaled in a controller hardware event. Examples of
the former are included in the patch changelogs.
Driver software is required to suspend the RNC in a "TX/RX Suspended"
condition before any outstanding commands can be terminated. Failure to
guarantee this can lead to a complete hardware hang condition. Earlier
versions of the driver software did not guarantee that an RNC was
correctly managed before I/O termination, and so operated in an unsafe
way.
Further, the driver performed unnecessary contortions to preserve the
remote device command state and so was more complicated than it needed
to be. A simplifying driver assumption is that once an I/O has entered
the error handler path without having completed in the target, the
requirement on the driver is that all use of the sas_task must end.
Beyond that, recovery of operation is dependent on libsas and other
components to reset, rediscover and reconfigure the device before normal
operation can restart. In the driver, this simplifying assumption meant
that the RNC management could be reduced to entry into the suspended
state, terminating the targeted I/O request, and resuming the RNC as
needed for device-specific management such as an SSP Abort Task or LUN
Reset Management request.

doesn't work for BRDCM cards as they set an mfs of 2048 regardless
of whether the switch returns a larger mfs.
This patch validates the new mfs against the upper and lower spec

Currently fc_host mfs is not getting updated in
case its changed during FLOGI and that leaves fc_host
to show its initial old value in sysfs, so instead
have fc_host mfs updated along with updating lport mfs
during FLOGI.
Also in case of bad mfs during flogi, error out
instead of continuing with flogi.
[ Changes made by Robert Love: condition to '>=' and
added printing of lport->mfs in DBG statement. FLOGI
resp processing failed without being able to compare
FCoE MFS 2112 against an incoming MFS of 2112 ]

SCSI updates from James Bottomley:
"The update includes the usual assortment of driver updates (lpfc,
qla2xxx, qla4xxx, bfa, bnx2fc, bnx2i, isci, fcoe, hpsa) plus a huge
amount of infrastructure work in the SAS library and transport class
as well as an iSCSI update. There's also a new SCSI based virtio
driver."

This patch adds support for Fabric Device Management
Interface as per FC-GS-4 spec. in libfc. Any driver
making use of libfc can enable fdmi state machine
for a given lport.
If lport has enabled FDMI support the lport state
machine will transition into FDMI after completing
the DNS states and before entering the SCR state.
The FDMI state transition is such that if there is an
error, it won't stop the lport state machine from
transitioning and the it will behave as if there was
no FDMI support.
The FDMI HBA attributes are registed with the Management
server via Register HBA (RHBA) command and the port
attributes are reigstered using the Register Port(RPA)
command.

Avoid that sparse complains about missing declarations for local
functions by declaring these static or by adding an #include directive.
Add the __percpu annotation where it is missing.

The module.h header was implicitly present everywhere, so files
with no explicit include of the module infrastructure would build
anyway. We are now removing the implicit include, and so we need
to call out the module.h file that we need explicitly.

Adds more cases to do flogi retry, now also retry
on getting bad response due to either no ELS response
or flogi response payload length not large enough.
In those cases flogi was not retried and that
was leaving lport offline.
