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.

[SCSI] libfcoe: Add fcoe_sysfs

This patch adds a 'fcoe bus' infrastructure to the kernel
that is driven by changes to libfcoe which allow LLDs to
present FIP (FCoE Initialization Protocol) discovered
entities and their attributes to user space via sysfs.

This patch adds the following APIs-

fcoe_ctlr_device_add
fcoe_ctlr_device_delete
fcoe_fcf_device_add
fcoe_fcf_device_delete

They allow the LLD to expose the FCoE ENode Controller
and any discovered FCFs (Fibre Channel Forwarders, e.g.
FCoE switches) to the user. Each of these new devices
has their own bus_type so that they are grouped together
for easy lookup from a user space application. Each
new class has an attribute_group to expose attributes
for any created instances. The attributes are-

fcoe_ctlr_device
* fcf_dev_loss_tmo
* lesb_link_fail
* lesb_vlink_fail
* lesb_miss_fka
* lesb_symb_err
* lesb_err_block
* lesb_fcs_error

fcoe_fcf_device
* fabric_name
* switch_name
* priority
* selected
* fc_map
* vfid
* mac
* fka_peroid
* fabric_state
* dev_loss_tmo

A device loss infrastructre similar to the FC Transport's
is also added by this patch. It is nice to have so that a
link flapping adapter doesn't continually advance the count
used to identify the discovered FCF. FCFs will exist in a
"Disconnected" state until either the timer expires or the
FCF is rediscovered and becomes "Connected."

This patch generates a few checkpatch.pl WARNINGS that
I'm not sure what to do about. They're macros modeled
around the FC Transport attribute building macros, which
have the same 'feature' where the caller can ommit a cast
in the argument list and no cast occurs in the code. I'm
not sure how to keep the code condensed while keeping the
macros. Any advice would be appreciated.
