| 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. |
