[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.

Description: 'FCoE Controller' instances on the fcoe bus
Attributes:
fcf_dev_loss_tmo: Device loss timeout peroid (see below). Changing
this value will change the dev_loss_tmo for all
FCFs discovered by this controller.

Serivces error count.
Notes: ctlr_X (global increment starting at 0)
What: /sys/bus/fcoe/fcf_X
Date: March 2012
KernelVersion: TBD
Contact: Robert Love <robert.w.love@intel.com>, devel@open-fcoe.org
Description: 'FCoE FCF' instances on the fcoe bus. A FCF is a Fibre Channel
Forwarder, which is a FCoE switch that can accept FCoE
(Ethernet) packets, unpack them, and forward the embedded
Fibre Channel frames into a FC fabric. It can also take
outbound FC frames and pack them in Ethernet packets to
be sent to their destination on the Ethernet segment.
Attributes:
fabric_name: Identifies the fabric that the FCF services.
switch_name: Identifies the FCF.
priority: The switch's priority amongst other FCFs on the same
fabric.
selected: 1 indicates that the switch has been selected for use;
0 indicates that the swich will not be used.
fc_map: The Fibre Channel MAP
vfid: The Virtual Fabric ID
mac: The FCF's MAC address
fka_peroid: The FIP Keep-Alive peroid
fabric_state: The internal kernel state
"Unknown" - Initialization value
"Disconnected" - No link to the FCF/fabric
"Connected" - Host is connected to the FCF
"Deleted" - FCF is being removed from the system
dev_loss_tmo: The device loss timeout peroid for this FCF.
Notes: A device loss infrastructre similar to the FC Transport's
is present in fcoe_sysfs. 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 and the
FCF becomes "Deleted" or the FCF is rediscovered and becomes
"Connected."
Users: The first user of this interface will be the fcoeadm application,
which is commonly packaged in the fcoe-utils package.
