|  | 33 | Description:	'FCoE FCF' instances on the fcoe bus. A FCF is a Fibre Channel | 
|  | 34 | Forwarder, which is a FCoE switch that can accept FCoE | 
|  | 35 | (Ethernet) packets, unpack them, and forward the embedded | 
|  | 36 | Fibre Channel frames into a FC fabric. It can also take | 
|  | 37 | outbound FC frames and pack them in Ethernet packets to | 
|  | 38 | be sent to their destination on the Ethernet segment. | 
|  | 39 | Attributes: | 
|  | 40 |  | 
|  | 41 | fabric_name: Identifies the fabric that the FCF services. | 
|  | 42 |  | 
|  | 43 | switch_name: Identifies the FCF. | 
|  | 44 |  | 
|  | 45 | priority:    The switch's priority amongst other FCFs on the same | 
|  | 46 | fabric. | 
|  | 47 |  | 
|  | 48 | selected:    1 indicates that the switch has been selected for use; | 
|  | 49 | 0 indicates that the swich will not be used. | 
|  | 50 |  | 
|  | 51 | fc_map:      The Fibre Channel MAP | 
|  | 52 |  | 
|  | 53 | vfid:	     The Virtual Fabric ID | 
|  | 54 |  | 
|  | 55 | mac:         The FCF's MAC address | 
|  | 56 |  | 
|  | 57 | fka_peroid:  The FIP Keep-Alive peroid | 
|  | 58 |  | 
|  | 59 | fabric_state: The internal kernel state | 
|  | 60 | "Unknown" - Initialization value | 
|  | 61 | "Disconnected" - No link to the FCF/fabric | 
|  | 62 | "Connected" - Host is connected to the FCF | 
|  | 63 | "Deleted" - FCF is being removed from the system | 
|  | 64 |  | 
|  | 65 | dev_loss_tmo: The device loss timeout peroid for this FCF. | 
|  | 66 |  | 
|  | 67 | Notes: A device loss infrastructre similar to the FC Transport's | 
|  | 68 | is present in fcoe_sysfs. It is nice to have so that a | 
|  | 69 | link flapping adapter doesn't continually advance the count | 
|  | 70 | used to identify the discovered FCF. FCFs will exist in a | 
|  | 71 | "Disconnected" state until either the timer expires and the | 
|  | 72 | FCF becomes "Deleted" or the FCF is rediscovered and becomes | 
|  | 73 | "Connected." | 
|  | 74 |  | 
|  | 75 |  | 
|  | 76 | Users: The first user of this interface will be the fcoeadm application, | 
|  | 77 | which is commonly packaged in the fcoe-utils package. |
