Merge git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (69 commits) [SCSI] scsi_transport_fc: Fix synchronization issue while deleting vport [SCSI] bfa: Update the driver version to 2.1.2.1. [SCSI] bfa: Remove unused header files and did some cleanup. [SCSI] bfa: Handle SCSI IO underrun case. [SCSI] bfa: FCS and include file changes. [SCSI] bfa: Modified the portstats get/clear logic [SCSI] bfa: Replace bfa_get_attr() with specific APIs [SCSI] bfa: New portlog entries for events (FIP/FLOGI/FDISC/LOGO). [SCSI] bfa: Rename pport to fcport in BFA FCS. [SCSI] bfa: IOC fixes, check for IOC down condition. [SCSI] bfa: In MSIX mode, ignore spurious RME interrupts when FCoE ports are in FW mismatch state. [SCSI] bfa: Fix Command Queue (CPE) full condition check and ack CPE interrupt. [SCSI] bfa: IOC recovery fix in fcmode. [SCSI] bfa: AEN and byte alignment fixes. [SCSI] bfa: Introduce a link notification state machine. [SCSI] bfa: Added firmware save clear feature for BFA driver. [SCSI] bfa: FCS authentication related changes. [SCSI] bfa: PCI VPD, FIP and include file changes. [SCSI] bfa: Fix to copy fpma MAC when requested by user space application. [SCSI] bfa: RPORT state machine: direct attach mode fix. ...
