 | What:		/sys/bus/fcoe/fcf_X | 
 | Date:		March 2012 |

 | 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. |
