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)." * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (45 commits) [SCSI] fix scsi_wait_scan [SCSI] fix async probe regression [SCSI] be2iscsi: fix dma free size mismatch regression [SCSI] qla4xxx: Update driver version to 5.02.00-k17 [SCSI] qla4xxx: Capture minidump for ISP82XX on firmware failure [SCSI] qla4xxx: Add change_queue_depth API support [SCSI] qla4xxx: Fix clear ddb mbx command failure issue. [SCSI] qla4xxx: Fix kernel panic during discovery logout. [SCSI] qla4xxx: Correct early completion of pending mbox. [SCSI] fcoe, bnx2fc, libfcoe: SW FCoE and bnx2fc use FCoE Syfs [SCSI] libfcoe: Add fcoe_sysfs [SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a member [SCSI] fcoe: Allocate fcoe_ctlr with fcoe_interface, not as a member [SCSI] Fix dm-multipath starvation when scsi host is busy [SCSI] ufs: fix potential NULL pointer dereferencing error in ufshcd_prove.

33Description: '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.
39Attributes:
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
67Notes: 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
76Users: The first user of this interface will be the fcoeadm application,
77 which is commonly packaged in the fcoe-utils package.
