+Description: The FCoE bus. Attributes in this directory are control interfaces.
+Attributes:
+
+ ctlr_create: 'FCoE Controller' instance creation interface. Writing an
+ <ifname> to this file will allocate and populate sysfs with a
+ fcoe_ctlr_device (ctlr_X). The user can then configure any
+ per-port settings and finally write to the fcoe_ctlr_device's
+ 'start' attribute to begin the kernel's discovery and login
+ process.
+
+ ctlr_destroy: 'FCoE Controller' instance removal interface. Writing a
+ fcoe_ctlr_device's sysfs name to this file will log the
+ fcoe_ctlr_device out of the fabric or otherwise connected
+ FCoE devices. It will also free all kernel memory allocated
+ for this fcoe_ctlr_device and any structures associated
+ with it, this includes the scsi_host.

-Description: 'FCoE Controller' instances on the fcoe bus
+Description: 'FCoE Controller' instances on the fcoe bus.
+ The FCoE Controller now has a three stage creation process.
+ 1) Write interface name to ctlr_create 2) Configure the FCoE
+ Controller (ctlr_X) 3) Enable the FCoE Controller to begin
+ discovery and login. The FCoE Controller is destroyed by
+ writing it's name, i.e. ctlr_X to the ctlr_delete file.
+
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.
+ mode: Display or change the FCoE Controller's mode. Possible
+ modes are 'Fabric' and 'VN2VN'. If a FCoE Controller
+ is started in 'Fabric' mode then FIP FCF discovery is
+ initiated and ultimately a fabric login is attempted.
+ If a FCoE Controller is started in 'VN2VN' mode then
+ FIP VN2VN discovery and login is performed. A FCoE
+ Controller only supports one mode at a time.
+
+ enabled: Whether an FCoE controller is enabled or disabled.
+ 0 if disabled, 1 if enabled. Writing either 0 or 1
+ to this file will enable or disable the FCoE controller.
+
lesb/link_fail: Link Error Status Block (LESB) link failure count.
lesb/vlink_fail: Link Error Status Block (LESB) virtual link
