Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull final round of SCSI updates from James Bottomley:
"This is primarily another round of driver updates (bnx2fc, qla2xxx,
qla4xxx) including the target mode driver for qla2xxx. We've also got
a couple of regression fixes (async scanning, broken this merge window
and a fix to a long standing break in the scsi_wait_scan module)."

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. |
