* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6: (31 commits)
  [SCSI] qla2xxx: Update version number to 8.03.00-k4.
  [SCSI] qla2xxx: Correct overwrite of pre-assigned init-control-block structure size.
  [SCSI] qla2xxx: Correct truncation in return-code status checking.
  [SCSI] qla2xxx: Correct vport delete bug.
  [SCSI] qla2xxx: Use correct value for max vport in LOOP topology.
  [SCSI] qla2xxx: Correct address range checking for option-rom updates.
  [SCSI] fcoe: Change fcoe receive thread nice value from 19 (lowest priority) to -20
  [SCSI] fcoe: fix handling of pending queue, prevent out of order frames (v3)
  [SCSI] fcoe: Out of order tx frames was causing several check condition SCSI status
  [SCSI] fcoe: fix kfree(skb)
  [SCSI] fcoe: ETH_P_8021Q is already in if_ether and fcoe is not using it anyway
  [SCSI] libfc: do not change the fh_rx_id of a recevied frame
  [SCSI] fcoe: Correct fcoe_transports initialization vs. registration
  [SCSI] fcoe: Use setup_timer() and mod_timer()
  [SCSI] libfc, fcoe: Remove unnecessary cast by removing inline wrapper
  [SCSI] libfc, fcoe: Cleanup function formatting and minor typos
  [SCSI] libfc, fcoe: Fix kerneldoc comments
  [SCSI] libfc: Cleanup libfc_function_template comments
  [SCSI] libfc: check for err when recv and state is incorrect
  [SCSI] libfc: rename rp to rdata in fc_disc_new_target()
