97c8389d54 [SCSI] fcoe, libfcoe: Add support for FIP. FCoE discovery and keep-alive.
FIP is the new standard way to discover Fibre-Channel Forwarders (FCFs)
by sending solicitations and listening for advertisements from FCFs.

It also provides for keep-alives and period advertisements so that both
parties know they have connectivity.  If the FCF loses connectivity to
the storage fabric, it can send a Link Reset to inform the E_node.

This version is also compatible with pre-FIP implementations, so no
configured selection between FIP mode and non-FIP mode is required.

We wait a couple seconds after sending the initial solicitation
and then send an old-style FLOGI.  If we receive any FIP frames,
we use FIP only mode.  If the old FLOGI receives a response,
we disable FIP mode.  After every reset or link up, this
determination is repeated.

to scsi_host priv data.

7f34914295 [SCSI] fcoe: removes default sw transport code file fcoe_sw.c
Moves only required code from fcoe_sw.c to libfcoe.c towards having
just one source file for fcoe module, this gets rid off default sw
transport code in a separate fcoe_sw.c file.

Very minor renaming along this move, dropped _sw_ or _SW_ use
in names and replaced them by _if_ as a auxiliary interface
functions. Now some of these funcs can be removed or merged with
other func after fcoe transport is gone, but that should be
in another patch to keep this patch simple.

Now the libfcoe.c file name for fcoe module doesn't go along well,
so the libfcoe.c file renaming to fcoe.c as the only single fcoe
module file is done in next patch to keep this patch clean
and small for review.

5919a59503 [SCSI] fcoe: prep work to completely remove fc_transport_fcoe code
The fcoe transport code was added for generic FCoE transport
infrastructure to allow additional offload related module loading
on demand, this is not required anymore after recently added
different offload approach by having offload related func ops
in netdev.

This patch removes fcoe transport related code use, calls functions
directly between existing libfcoe.c and fcoe_sw.c for now, for
example fcoe_sw_destroy and fcoe_sw_create calling.

The fcoe_sw.c and libfcoe.c code will be further consolidated in
later patches and then also the default fcoe sw transport code
file fcoe_sw.c will be completely removed.

The fcoe transport code files are completely removed in next
patch to keep this patch simple for reviewing.

[This patch is an update to a previous patch. This update
resolves a build error as well as fixes a defect related to
not calling fc_release_transport().]

8976f424d4 [SCSI] fcoe: create/destroy fcoe Rx threads on CPU hotplug events
This patch adds support for dynamically created Rx threads
upon CPU hotplug events.

There were existing synchronization problems that this patch
attempts to resolve. The main problem had to do with fcoe_rcv()
running in a different context than the hotplug notifications.
This opened the possiblity that fcoe_rcv() would target a Rx
thread for a skb. However, that thread could become NULL if
the CPU was made offline.

This patch uses the Rx queue's (a skb_queue) lock to protect
the thread it's associated with and we use the 'thread' member
of the fcoe_percpu_s to determine if the thread is ready to
accept new skbs.

The patch also attempts to do a better job of cleaning up, both
if hotplug registration fails as well as when the module is
removed.

fix incorrect use of __cpuinitdata.

a9bddd7463 [SCSI] fix recovered error handling
We have a problem with recovered error handling in that any command
which goes down as BLOCK_PC but which returns a sense code of RECOVERED
ERROR gets completed with -EIO.  For actual SG_IO commands, this doesn't
matter at all, since the error return code gets dropped in favour of
req->errors which contain the SCSI completion code.

However, if this command is part of the block system, then it will pay
attention to the returned error code.  In particularly if a SYNCHRONIZE
CACHE from a barrier command completes with RECOVERED ERROR, the
resulting -EIO on the barrier causes block to error the request and
return it to the filesystem.  Fix this by converting the -EIO for
recovered error to zero, plus remove the printing of this from sd and sr
so the message isn't double printed.

a2f5bfcf71 [SCSI] aic7xxx: leaves timer running on init failure
aic79xx leaves timers inserted when ahd_init() (which inserts
two timers at its very end) succeeds but ahd_pci_map_int()
fails. In this case ahd->init_level gets incremented to 5 only
when that function succeeds, but ahd_free() calls ahd_shutdown()
only when ahd->init_level == 5, and ahd_shutdown() is where the
timers get removed. Since the freeing of the IRQ is not controlled
by ahd->init_level, we should increment init_level prior to
calling ahd_pci_map_int().

2533cf671d [SCSI] qla2xxx: Correct ISP abort semantics for NVRAM, VPD, and flash update.
Ensure that an ISP-abort has completed before performing any
update.  After the update do not wait for an ISP-abort completion,
instead just wait until the ISP is reset.  This avoids long
delays due to waiting for loop ready in qla2x00_abort_isp().

1d2874de80 [SCSI] qla2xxx: Add Flash-Access-Control support for recent ISPs.
Given the low-level interface varies from one flash-part
manufacturer to the next, the Flash-Access-Control (FAC) mailbox
command makes the specific flash type transparent to the driver
by encapsulating a basic set of accessor and update routines.
Use these new routines where applicable by querying FAC opcode
get-sector-size at init-time.

b997876987 [SCSI] qla2xxx: Ensure the timer and DPC routines complete prior to midlayer tear-down.
Since the routines can/will use resources such as devices and
rports that aren't valid after midlayer tear-down, correct this
potential race, by stopping the offending during the early stages
of the remove() callback.

be67e6530b [SCSI] qla2xxx: Preserve an fcport's loop-id after terminate_rport_io().
Since in some circumstances, login-retries may be occuring in the
background via the DPC routine.  This race, in the inadvertant
setting of the loop-id to 'NONE' breaks the existing retry logic.
