Julia Lawall b0d5e15cc4 [SCSI] bnx2fc: adjust duplicate test
Delete successive tests to the same location.  The code tested the result
of a previous allocation, that itself was already tested.  It is changed to
test the result of the most recent allocation.

follows: (http://coccinelle.lip6.fr/)

Bhanu Prakash Gollapudi e7f4fed5fa [SCSI] bnx2fc: Map the doorbell register between offload and enable requests
We used to map doorbell register after FW enable request is complete.
This causes a race condition when unsolicited event is received, and FW
sends a CQE for it. Since the doorbell is not mapped, driver does not
arm CQ, which means FW will not notify the driver for further CQ
completions.  To resolve this, map the doorbell between offload and
enable, so that driver is ready to receive the unsolicited packets and
arm the CQ as soon as FW enable is performed.

Greg Kroah-Hartman 6f03979051 Drivers: scsi: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Robert Love 6e89ea3f10 bnx2fc: Use the fcoe_sysfs control interface
This patch adds support for the new fcoe_sysfs
control interface to bnx2fc.ko. It keeps the deprecated
interface in tact and therefore either the legacy
or the new control interfaces can be used. A mixed mode
is not supported. A user must either use the new
interfaces or the old ones, but not both.

The fcoe_ctlr's link state is now driven by both the
netdev link state as well as the fcoe_ctlr_device's
enabled attribute. The link must be up and the
fcoe_ctlr_device must be enabled before the FCoE
Controller starts discovery or login.

Robert Love 6a891b071b libfcoe, fcoe, bnx2fc: Add new fcoe control interface
This patch does a few things.

1) Makes /sys/bus/fcoe/ctlr_{create,destroy} interfaces.
   These interfaces take an <ifname> and will either
   create an FCoE Controller or destroy an FCoE
   Controller depending on which file is written to.

   The new FCoE Controller will start in a DISABLED
   state and will not do discovery or login until it
   is ENABLED. This pause will allow us to configure
   the FCoE Controller before enabling it.

2) Makes the 'mode' attribute of a fcoe_ctlr_device
   writale. This allows the user to configure the mode
   in which the FCoE Controller will start in when it
   is ENABLED.

   Possible modes are 'Fabric', or 'VN2VN'.

   The default mode for a fcoe_ctlr{,_device} is 'Fabric'.
   Drivers must implement the set_fcoe_ctlr_mode routine
   to support this feature.

   libfcoe offers an exported routine to set a FCoE
   Controller's mode. The mode can only be changed
   when the FCoE Controller is DISABLED.

   This patch also removes the get_fcoe_ctlr_mode pointer
   in the fcoe_sysfs function template, the code in
   fcoe_ctlr.c to get the mode and the assignment of
   the fcoe_sysfs function pointer to the fcoe_ctlr.c
   implementation (in fcoe and bnx2fc). fcoe_sysfs can
   return that value for the mode without consulting the
   LLD.

3) Make a 'enabled' attribute of a fcoe_ctlr_device. On a
   read, fcoe_sysfs will return the attribute's value. On
   a write, fcoe_sysfs will call the LLD (if there is a
   callback) to notifiy that the enalbed state has changed.

This patch maintains the old FCoE control interfaces as
module parameters, but it adds comments pointing out that
the old interfaces are deprecated.

During parity errors, the ramrods are not issued to FW. bnx2fc waits for the
timeout value, and proceeds with cleaning up the IOs. Since we are already
out-of-sync with FW, cleanup commands timeout too, and do not get the
completion.  This operation takes 36 secs for each session to upload causing
huge delays. To fix this, bnx2fc now gets a PARITY_ERROR from cnic driver, and
upon failure, the driver does not issue any commands to the FW and finishes the
upload process sooner.

Joe Perches 3db8cc1065 [SCSI] bnx2fc: Reduce object size by consolidating formats
Deduplication of formats and consolidating tests
makes the object much smaller.

Add bnx2fc_debug.c, add functions for a few logging
functions (BNX2FC_IO_DBG, BNX2FC_TGT_DBG, BNX2FC_HBA_DBG).
Use printf extension %pV.
Add and use pr_fmt and pr_<level>.
Move the debug #include below structure definitions.

Robert Love 8d55e507d2 [SCSI] fcoe, bnx2fc, libfcoe: SW FCoE and bnx2fc use FCoE Syfs
This patch has the SW FCoE driver and the bnx2fc
driver make use of the new fcoe_sysfs API added
earlier in this patch series.

After this patch a fcoe_ctlr_device is allocated with
private data in this order.

+------------------+   +------------------+
| fcoe_ctlr_device |   | fcoe_ctlr_device |
+------------------+   +------------------+
| fcoe_ctlr        |   | fcoe_ctlr        |
+------------------+   +------------------+
| fcoe_interface   |   | bnx2fc_interface |
+------------------+   +------------------+

libfcoe also takes part in this new model since it
discovers and manages fcoe_fcf instances. The memory
allocation is different for FCFs. I didn't want to
impact libfcoe's fcoe_fcf processing, so this patch
creates fcoe_fcf_device instances for each discovered
fcoe_fcf. The two are paired using a (void * priv)
member of the fcoe_ctlr_device. This allows libfcoe
to continue maintaining its list of fcoe_fcf instances
and simply attaches and detaches them from existing
or new fcoe_fcf_device instances.

Robert Love fd8f89027d [SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a member
Currently the fcoe_ctlr associated with an interface is allocated
    as a member of struct bnx2fc_interface. This causes problems when
    when later patches attempt to use the new fcoe_sysfs APIs which
    allow us to allocate the bnx2fc_interface as private data to a
    fcoe_ctlr_device instance. The problem is that libfcoe wants to
    be able use pointer math to find a fcoe_ctlr's fcoe_ctlr_device
    as well as finding a fcoe_ctlr_device's assocated fcoe_ctlr. To
    do this we need to allocate the fcoe_ctlr_device, with private
    data for the LLD. The private data will contain the fcoe_ctlr
    and its private data will be the bnx2fc_interface.

    +-------------------+
    | fcoe_ctlr_device  |
    +-------------------+
    | fcoe_ctlr         |
    +-------------------+
    | bnx2fc_interface  |
    +-------------------+

    This prep work will allow us to go from a fcoe_ctlr_device
    instance to its fcoe_ctlr as well as from a fcoe_ctlr to its
    fcoe_ctlr_device once the fcoe_sysfs API is in use (later
    patches in this series).

Bhanu Prakash Gollapudi 44c570b5b0 [SCSI] bnx2fc: Handle LOGO flooding from the target
Host drops sessions when flood of unsolicited LOGOs are received from the
target. Because of unsufficient PLOGI retries, upon exceeding the retry count
of 3, the target sessions are dropped. Increased the retry count to 255 to
allow sufficient retries in this scenario.
