Pull SCSI target updates from Nicholas Bellinger:
 "The highlights this round include:

   - enable dual mode (initiator + target) qla2xxx operation. (Quinn +
     Himanshu)

   - add a framework for qla2xxx async fabric discovery. (Quinn +
     Himanshu)

   - enable iscsi PDU DDP completion offload in cxgbit/T6 NICs. (Varun)

   - fix target-core handling of aborted failed commands. (Bart)

   - fix a long standing target-core issue NULL pointer dereference with
     active I/O LUN shutdown. (Rob Millner + Bryant + nab)"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (44 commits)
  target: Add counters for ABORT_TASK success + failure
  iscsi-target: Fix early login failure statistics misses
  target: Fix NULL dereference during LUN lookup + active I/O shutdown
  target: Delete tmr from list before processing
  target: Fix handling of aborted failed commands
  uapi: fix linux/target_core_user.h userspace compilation errors
  target: export protocol identifier
  qla2xxx: Fix a warning reported by the "smatch" static checker
  target/iscsi: Fix unsolicited data seq_end_offset calculation
  target/cxgbit: add T6 iSCSI DDP completion feature
  target/cxgbit: Enable DDP for T6 only if data sequence and pdu are in order
  target/cxgbit: Use T6 specific macros to get ETH/IP hdr len
  target/cxgbit: use cxgb4_tp_smt_idx() to get smt idx
  target/iscsi: split iscsit_check_dataout_hdr()
  target: Remove command flag CMD_T_DEV_ACTIVE
  target: Remove command flag CMD_T_BUSY
  target: Move session check from target_put_sess_cmd() into target_release_cmd_kref()
  target: Inline transport_cmd_check_stop()
  target: Remove an overly chatty debug message
  target: Stop execution if CMD_T_STOP has been set
