59ccf86fe6 qed: Add driver infrastucture for handling mfw requests.
MFW requests the TLVs in interrupt context. Extracting of the required
data from upper layers and populating of the TLVs require process context.
The patch adds work-queues for processing the tlv requests. It also adds
the implementation for requesting the tlv values from appropriate protocol
driver.

2528c38993 qed: Add support for tlv request processing.
The patch adds driver support for processing TLV requests/repsonses
from the mfw and upper driver layers respectively. The implementation
reads the requested TLVs from the shared memory, requests the values
from upper layer drivers, populates this info (TLVs) shared memory and
notifies MFW about the TLV values.

cac6f69154 qed: Add support for Unified Fabric Port.
This patch adds driver changes for supporting the Unified Fabric Port
(UFP). This is a new paritioning mode wherein MFW provides the set of
parameters to be used by the device such as traffic class, outer-vlan
tag value, priority type etc. Drivers receives this info via notifications
from mfw and configures the hardware accordingly.

0bc5fe8572 qed*: Refactor mf_mode to consist of bits.
`mf_mode' field indicates the multi-partitioning mode the device is
configured to. This method doesn't scale very well, adding a new MF mode
requires going over all the existing conditions, and deciding whether those
are needed for the new mode or not.
The patch defines a set of bit-fields for modes which are derived according
to the mode info shared by the MFW and all the configuration would be made
according to those. To add a new mode, there would be a single place where
we'll need to go and choose which bits apply and which don't.

809c45a091 qed* : Add new TLV to request PF to update MAC in bulletin board
There may be a need for VF driver to request PF to explicitly update its
bulletin with a MAC address.
e.g. When user assigns a MAC address to VF while VF is still down,
and PF's bulletin board contains different MAC address, in this case,
when VF's interface is brought up, it gets loaded with MAC address from
bulletin board which is not desirable.

To handle this corner case, we need a new TLV to request PF to update
its bulletin board with suggested MAC.

This request will be honored only for trusted VFs.

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

0518c12f1f qed*: LL2 callback operations
LL2 today is interrupt driven - when tx/rx completion arrives [or any
other indication], qed needs to operate on the connection and pass
the information to the protocol-driver [or internal qed consumer].
Since we have several flavors of ll2 employeed by the driver,
each handler needs to do an if-else to determine the right functionality
to use based on the connection type.

In order to make things more scalable [given that we're going to add
additional types of ll2 flavors] move the infrastrucutre into using
a callback-based approach - the callbacks would be provided as part
of the connection's initialization parameters.

Content-wise, the firmware contains fixes to various issues exposed
since the release of the previous firmware, including:
 - Corrects iSCSI fast retransmit when data digest is enabled.
 - Stop draining packets when receiving several consecutive PFCs.
 - Prevent possible assertion when consecutively opening/closing
   many connections.
 - Prevent possible assertion due to too long BDQ fetch time.

In addition, the new firmware would allow us to later add iWARP support
in qed and qedr.

3da7a37ae6 qed*: Handle-based L2-queues.
The driver needs to maintain several FW/HW-indices for each one of
its queues. Currently, that mapping is done by the QED where it uses
an rx/tx array of so-called hw-cids, populating them whenever a new
queue is opened and clearing them upon destruction of said queues.

This maintenance is far from ideal - there's no real reason why
QED needs to maintain such a data-structure. It becomes even worse
when considering the fact that the PF's queues and its child VFs' queues
are all mapped into the same data-structure.
As a by-product, the set of parameters an interface needs to supply for
queue APIs is non-trivial, and some of the variables in the API
structures have different meaning depending on their exact place
in the configuration flow.

This patch re-organizes the way L2 queues are configured and maintained.
In short:
  - Required parameters for queue init are now well-defined.
  - Qed would allocate a queue-cid based on parameters.
    Upon initialization success, it would return a handle to caller.
  - Queue-handle would be maintained by entity requesting queue-init,
    not necessarily qed.
  - All further queue-APIs [update, destroy] would use the opaque
    handle as reference for the queue instead of various indices.

The possible owners of such handles:
  - PF queues [qede] - complete handles based on provided configuration.
  - VF queues [qede] - fw-context-less handles, containing only relative
    information; Only the PF-side would need the absolute indices
    for configuration, so they're omitted here.
  - VF queues [qed, PF-side] - complete handles based on VF initialization.

6d937acfb3 qed: Optimize qed_chain datapath usage
The chain structure and functions are widely used by the qed* modules,
both for configuration and datapath.
E.g., qede's Tx has one such chain and its Rx has two.

Currently, the strucutre's fields which are required for datapath
related functions [produce/consume] are intertwined with fields which

2edbff8dcb qed: Learn resources from management firmware
Currently, each interfaces assumes it receives an equal portion
of HW/FW resources, but this is wasteful - different partitions
[and specifically, parititions exposing different protocol support]
might require different resources.

Implement a new resource learning scheme where the information is
received directly from the management firmware [which has knowledge
of all of the functions and can serve as arbiter].

Management firmware is interested in various tidbits about

related fields [MTU, primtary MAC, etc.].
This adds the necessray logic to update MFW with such configurations,
some of which are passed directly via qed while for others APIs
are provide so that qede would be able to later configure if needed.

This also introduces a new default configuration for MTU which would
replace the default inherited by being an ethernet device.

0189efb8f4 qed*: Fix Kconfig dependencies with INFINIBAND_QEDR
The qedr driver would require a tristate Kconfig option [to allow
it to compile as a module], and toward that end we've added the
INFINIBAND_QEDR option. But as we've made the compilation of the
qed/qede infrastructure required for RoCE dependent on the option
we'd be facing linking difficulties in case that QED=y or QEDE=y,
and INFINIBAND_QEDR=m.

To resolve this, we seperate between the INFINIBAND_QEDR option
and the infrastructure support in qed/qede by introducing a new
QED_RDMA option which would be selected by INFINIBAND_QEDR but would
be a boolean instead of a tristate; Following that, the qed/qede is
fixed based on this new option so that all config combinations would
be supported.

Communication between VF and PF is based on a dedicated HW channel;
VF will prepare a messge, and by signaling the HW the PF would get a
notification of that message existance. The PF would then copy the
message, process it and DMA an answer back to the VF as a response.

The messages themselves are TLV-based - allowing easier backward/forward
compatibility.

This patch adds the infrastructure of the channel on the PF side -
starting with the arrival of the notification and ending with DMAing
the response back to the VF.

It also adds a dummy-response as reference, as it only lays the

fe7cd2bfda qed*: Conditions for changing link
There's some inconsistency in current logic determining whether the
link settings of a given interface can be changed; I.e., in all modes
other than the so-called `deault' mode the interfaces are forbidden from
changing the configuration - but even this rule is not applied to all
user APIs that may change the configuration.

Instead, let the core-module [qed] decide whether an interface can change
the configuration by supporting a new API function. We also revise the
current rule, allowing all interfaces to change their configurations while
laying the infrastructure for future modes where an interface would be
blocked from making such a configuration.

3f9b4a6972 qed: Lay infrastructure for vlan filtering offload
Today, interfaces are working in vlan-promisc mode; But once
vlan filtering offloaded would be supported, we'll need a method to
control it directly [e.g., when setting device to PROMISC, or when
running out of vlan credits].

This adds the necessary API for L2 client to manually choose whether to
accept all vlans or only those for which filters were configured.

This new FW is required for a lot of new SW features, including:
  - Vlan filtering offload
  - Encapsulation offload support
  - HW ingress aggregations
As well as paving the way for the possibility of adding storage protocols
in the future.

76a9a3642a qed: fix handling of concurrent ramrods.
Concurrent non-blocking slowpath ramrods can be completed
out-of-order on the completion chain. Recycling completed elements,
while previously sent elements are still completion pending,
can lead to overriding of active elements on the chain. Furthermore,
sending pending slowpath ramrods currently lacks the update of the
chain element physical pointer.

This patch:
* Ensures that ramrods are sent to the FW with
  consecutive echo values.
* Handles out-of-order completions by freeing only first
  successive completed entries.
* Updates the chain element physical pointer when copying
  a pending element into a free element for sending.

fe56b9e6a8 qed: Add module with basic common support
The Qlogic Everest Driver is the backend module for the QL4xxx ethernet
products by Qlogic.

This module serves two main purposes:
 1. It's responsible to contain all the common code that will be shared
    between the various drivers that would be used with said line of
    products. Flows such as chip initialization and de-initialization
    fall under this category.

 2. It would abstract the protocol-specific HW & FW components, allowing
    the protocol drivers to have a clean APIs which is detached in its
    slowpath configuration from the actual HSI.

This adds a very basic module without any protocol-specific bits.
I.e., this adds a basic implementation that almost entirely falls under
the first category.
