Mintz, Yuval be086e7c53 qed*: Utilize Firmware 8.15.3.0
This patch advances the qed* drivers into using the newer firmware -
This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.

It also introduces a major 4-Cached SGE change in firmware, which can be
seen in the storage drivers' changes.

In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].

Mintz, Yuval 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.

Mintz, Yuval 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
are required only for configuration purposes [init/destroy/etc.].

This patch re-arranges the chain structure so that all the fields which
are required for datapath usage could reside in a single cacheline instead
of the two which are required today.

Sudarsana Kalluru 0fefbfbaad qed*: Management firmware - notifications and defaults
Management firmware is interested in various tidbits about
the driver - including the driver state & several configuration
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.

Yuval Mintz 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.

  - Returning some slowpath configurations that are no longer needed
    on top of modern PFs, but would be required when working over

 - Better blocking of malicious VFs.
 - After FLR, Tx-switching [internal routing] of packets might

 - Deletion of unicast MAC filters would sometime have side-effect
   of corrupting the MAC filters configred for a device.
It also contains fixes for future qed* drivers that *hopefully* would be
sent for review in the near future.

In addition, it would allow driver some new functionality, including:
 - Allowing PF/VF driver compaitibility with old drivers [running
   pre-8.10.5.0 firmware].
 - Better debug facilities.

This would also bump the qed* driver versions to 8.10.9.20.

configure the device/firmware with the dcbx results. Management Firmware
is responsible for communicating the DCBX and driving the negotiation,
but the driver has responsibility of receiving async notification and
configuring the results in hw/fw. This patch also adds the dcbx support for
future protocols (e.g., FCoE) as preparation to their imminent submission.

Yuval Mintz 1408cc1fa4 qed: Introduce VFs
This adds the qed VFs for the first time -
The vfs are limited functions, with a very different PCI bar structure
[when compared with PFs] to better impose the related security demands
associated with them.

This patch includes the logic neccesary to allow VFs to successfully probe
[without actually adding the ability to enable iov].
This includes diverging all the flows that would occur as part of the pci
probe of the driver, preventing VF from accessing registers/memories it
can't and instead utilize the VF->PF channel to query the PF for needed
information.

Yuval Mintz 37bff2b9c6 qed: Add VF->PF channel infrastructure
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
groundwork of the communication; it doesn't really add support of any
actual messages.

Yuval Mintz 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.

Tomer Tayar 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.

    products. Flows such as chip initialization and de-initialization
    fall under this category.

 2. It would abstract the protocol-specific HW & FW components, allowing

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