Add the new fcoe_transport.c file that implements basic fcoe transport
interface. Eventually, the sysfs entries to create/destroy/enable/disable
an FCoE instance will be coming to the fcoe transport layer, who does a
look-up to find the corresponding transport provide and pass the corresponding
action over to the identified provider.
The fcoe.ko will become the default fcoe transport provider that can support
FCoE on any given netdev interfaces, as the Open-FCoE.org's default software
FCoE HBA solution. Any vendor specific FCoE HBA driver that is built on top
of Open-FCoE's kernel stack of libfc & libfcoe as well as the user land tool
of fcoe-utils can easily plug-in and start running FCoE on their network
interfaces. The fcoe.ko will be converted to act as the default provider if
no vendor specific transport provider is found, as it is always added to the
very end of the list of attached transports.

selection logic.
Problem:
In case of exchange responder case, EMA selection was defaulted to the
last EMA from EMA list (lport.ema_list). If exchange ID is selected
from offload pool and not setup DDP, resulting into incorrect
selection of EMA, and eventually dropping the packet because unable to
find exchange.
Fix:
Enhanced the exchange ID selection (depending upon request type and
exchange responder) Made necessary enhancement in EMA selection
algorithm.

When an SCST provider is registered, it needs to know what
local ports are available for configuration as targets.
Add a notifier chain that is invoked when any local port
that is added or deleted.
Maintain a global list of local ports and add an
interator function that calls a given function for
every existing local port. This is used when first
loading a provider.

Allow FC-4 provider modules to hook into libfc, mostly for targets.
This should allow any FC-4 module to handle PRLI requests and maintain
process-association states.
Each provider registers its ops with libfc and then will be called for
any incoming PRLI for that FC-4 type on any instance. The provider
can decide whether to handle that particular instance using any method
it likes, such as ACLs or other configuration information.
A count is kept of the number of successful PRLIs from the remote port.
Providers are called back with an implicit PRLO when the remote port
is about to be deleted or has been reset.
fc_lport_recv_req() now sends incoming FC-4 requests to FC-4 providers,
and there is a built-in provider always registered for handling
incoming ELS requests.
The call to provider recv() routines uses rcu_read_lock()
so that providers aren't removed during the call. That lock is very
cheap and shouldn't affect any performance on ELS requests.
Providers can rely on the RCU lock to protect a session lookup as well.

Allowing FCoE LOGO followed by CVL in this case prevents
FIP login back to the FCF and then keeps lport offline,
only FIP LOGO and CLV needs to be processed while in
FIP mode, therefore this patch drops FCoE LOGO in FIP mode.
Added fcoe_filter_frames() to filter out above mentioned LOGO
in fcoe rx path along with other existing filtering in code
for bad CRC frames. Adding separate fcoe_filter_frames function
helped with better code indentations and if needed then same
will allow adding more filters at one place in future.
This LOGO drop is added after FCP frames passed up to avoid
any additional checks on fast path for this.

vports are not grabbing module references but are
releasing them. This causes the module reference count
to decrement too many times and it wraps around past 0.
The solution is to do a module_put() in
fcoe_interface_release() so that the reference is only
released when the fcoe_interface is released. There is a
one-to-one relationship between the N_Port and the
fcoe_interface, so the module reference will only be
dropped when the N_Port is destroyed
To create symetry in the code this patch moves the
try_module_get() call into fcoe_interface_create(). This
means that only the N_Port will grab a reference to the
module when its corresponding fcoe_interface is created.
This patch also makes it so that the fcoe_interface_create()
routine encodes any error codes in the fcoe_interface
pointer returned. This way its caller, fcoe_create(), can
return an accurate error code.

FC_XID_UNKNOWN
The fsp's xfer_ddp is used as indication of the exchange id for the DDPed
I/O. We should always initialize it as FC_XID_UNKNOWN for a newly allocated
fsp, otherwise the fsp allocated in fc_fcp, i.e., not from queuecommand like
LUN RESET that is not doing DDP may still think DDP is setup for it since xid
0 is valid and goes on to call fc_fcp_ddp_done() in fc_fcp_resp() from
fc_tm_done(). So, set xfer_ddp as FC_XID_UNKNOWN in fc_fcp_pkt_alloc() now.
Also removes the setting of fsp->lp as it's already done when fsp is allocated.

Instead of just passing 'EIO' for any I/O error we should be
notifying the upper layers with more details about the cause
of this error.
Update the possible I/O errors to:
- ENOLINK: Link failure between host and target
- EIO: Retryable I/O error
- EREMOTEIO: Non-retryable I/O error
- EBADE: I/O error restricted to the I_T_L nexus
'Retryable' in this context means that an I/O error _might_ be
restricted to the I_T_L nexus (vulgo: path), so retrying on another
nexus / path might succeed.
'Non-retryable' in general refers to a target failure, so this
error will always be generated regardless of the I_T_L nexus
it was send on.
I/O errors restricted to the I_T_L nexus might be retried
on another nexus / path, but they should _not_ be queued
if no paths are available.

pm8001 manages its own list of pending works and cancel them on device
free. It is unnecessarily complex and has a race condition - the
works are canceled but not synced, so the work could still be running
during and after the data structures are freed.
This patch simplifies workqueue usage.
* A driver specific workqueue pm8001_wq is created to serve these
work items.
* To avoid confusion, the "queue" suffixes are dropped from work items
and functions.
* Delayed queueing was never used. pm8001_work now uses work_struct
instead.
* The driver no longer keeps track of pending works. All pm8001_works
are queued to pm8001_wq and the workqueue is flushed as necessary.
flush_scheduled_work() usage is removed during conversion.

and use the doorbell reset method if available (which doesn't
lock up the controller if you properly save and restore all
the PCI registers that you're supposed to.)

After a reset, we should first wait for the board to become "not ready",
and then wait for it to become "ready", instead of immediately
waiting for it to become "ready", and do this waiting *after*
restoring PCI config space registers. Also, only wait 10 secs
for board to become "not ready" after a reset (it should quickly
become not ready.)

Currently NetApp's VID/PID details in the INQUIRY response shows up as
'NETAPP' and 'LUN'. With upcoming scalable SAN ONTAP version on NetApp
controllers, the PID entry alone is being modified to 'LUN C-Mode' (to
distinguish current ONTAP LUNs from scalable ONTAP LUNs).
'LUN' would still suffice for matching 'LUN C-Mode' but best to
explicitly add these new NetApp LUNs to the device list.
