5 Description: 'FCoE Controller' instances on the fcoe bus
8 fcf_dev_loss_tmo: Device loss timeout peroid (see below). Changing
9 this value will change the dev_loss_tmo for all
10 FCFs discovered by this controller.
12 lesb/link_fail: Link Error Status Block (LESB) link failure count.
14 lesb/vlink_fail: Link Error Status Block (LESB) virtual link
17 lesb/miss_fka: Link Error Status Block (LESB) missed FCoE
18 Initialization Protocol (FIP) Keep-Alives (FKA).
20 lesb/symb_err: Link Error Status Block (LESB) symbolic error count.
22 lesb/err_block: Link Error Status Block (LESB) block error count.

32 Contact: Robert Love <robert.w.love@intel.com>, devel@open-fcoe.org
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.
41 fabric_name: Identifies the fabric that the FCF services.
43 switch_name: Identifies the FCF.
45 priority: The switch's priority amongst other FCFs on the same
48 selected: 1 indicates that the switch has been selected for use;
49 0 indicates that the swich will not be used.
51 fc_map: The Fibre Channel MAP
53 vfid: The Virtual Fabric ID
55 mac: The FCF's MAC address
57 fka_peroid: The FIP Keep-Alive peroid
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
65 dev_loss_tmo: The device loss timeout peroid for this FCF.
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
76 Users: The first user of this interface will be the fcoeadm application,
77 which is commonly packaged in the fcoe-utils package.
