Nicholas Bellinger 2d70c103fd [SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx series
Add LLD target mode for >= 24xx series HW.  This code was originally based on
external qla2x00t module based on 8.02.01-k4, and has been refactored to
push the bulk of code into mainline qla2xxx.ko LLD -> qla_target.c.

The implementation uses internal workqueues for I/O context submission
into tcm_qla2xxx code, and includes the struct qla_tgt_func_tmpl API for
external interaction to allow qla2xxx LDD to function without direct
target-core dependencies:

It also enables qla_target.c usage within existing qla2xxx LLD code.
This includes:

*) Addition of target mode specific members to existing data
structures in qla_def.h and struct qla_hw_data->tgt_ops using
qla_target.h:struct qla_tgt_func_tmpl

*) Addition of struct qla_tgt_func_tmpl and direct calls into
qla_target.c logic w/ qlt_* prefixed functions.

*) Addition of qla_iocb.c:qla2x00_req_pkt() for ring processing, and
qla2x00_issue_marker() for handling request/response queue processing
for target mode operation

*) Addition of various qla_tgt_mode_enabled() logic checks in
qla24xx_nvram_config(), qla2x00_initialize_adapter(), qla2x00_rff_id(),
qla2x00_abort_isp(), qla24xx_modify_vp_config(), and
qla2x00_vp_abort_isp().

By default the new qlini_mode module parameter is setting initiator-mode
to 'enabled' in order for 'modprobe qla2xxx' to continue to function as
expected in initiator only mode.  Enabling target-mode operation will
currently require a:

    modprobe qla2xxx qlini_mode="disabled"

in order to explictly disabled initiator mode and allow target-mode
to be enabled via tcm_qla2xxx configfs fabric callers.

(nab: Convert to qlini_mode='enabled' by default in qla_target.c)
(joern: Remove loop_id from qla_tgt_make_local_sess() arguments +
        Remove unused s_id + fix s_id endianness bug +
        simplify qla_tgt_abort_work)
(gerard: fix section __exit mismatch in qla_tgt_exit)
(arun: Capture ATIO queue during firmware dump + Send SCR in target mode +
       Target mode review comments)
(roland: Don't create duplicate target sessions to address tearing down
         ACLs with IO in flight + Add missing call to qlt_fc_port_deleted
	 call during qla2x00_schedule_rport_del timeout)

Arun Easi e02587d777 [SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.
This fix:
    - Disables app tag peeking; correct tag check will be added when the
      SCSI API is available.
    - Always derive ref_tag from scsi_get_lba()
    - Removes incorrect swap of FCP_LUN in FCP_CMND
    - Moves app-tag error check before ref-tag check. The reason being,
      currently there is no interface in SCSI to retrieve the app-tag
      for protection I/Os, so driver puts zero for app-tag in the
      firmware interface, but requests not to validate it, but when a
      ref-tag error is detected by firmware, it would put
      expected/actual tags for all the protection tags (guard/app/ref).
      As driver checks for app tag error first, a ref-tag error is
      incorrectly flagged as app-tag error.
    - Convert HBA specific checks to capability based.

get a list of Nx_Ports. This patch adds a GFF_ID call for each port
returned by GID_PT to get the FC4 type. If the FC4 type is not FCP SCSI
then the qla2xxx driver will not record that port in it's port database.
For switches that do not support the GFF_ID command, the behavior will be
for qla2xxx to store that port anyways.

Santosh Vernekar cdbb0a4f31 [SCSI] qla2xxx: Handle outstanding mbx cmds on hung f/w scenarios.
Outstanding mailbox commands, have no way to recover on f/w hung, and we
timeout on waiting for mbx response. This in turn affects the recovery process
as follows:
- We might already be in dpc while waiting for mbx to complete, so recovery for
that pci function will never get invoked. Reset Timeout (10 sec) is far less
than mbx timeout (30 sec).
- Other mbx cmds will get stuck due to serial mbx access.

Solution is to identify fw-hung scenario and handle outstanding mbx commands to
have an early-exit instead of waiting for response.
Other mbx commands waiting for access will also do an early-exit if fw-hung is
still applicable.
