[ Upstream commit ff9296966e5e00b0d0d00477b2365a178f0f06a3 ]
VF is always configured to drop control frames
(with reserved mac addresses) but to work LACP
on the VFs, it would require LACP control frames
to be forwarded or transmitted successfully.
This patch fixes this in such a way that trusted VFs
(marked through ndo_set_vf_trust) would be allowed to
pass the control frames such as LACP pdus.

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.

As per existing behavior, when PF sets a MAC address for a VF
(also called as forced MAC), VF is not allowed to change its
MAC address afterwards.
This puts the limitation on few use cases such as bonding of VFs,
where bonding driver asks VF to change its MAC address.
This patch uses a VF trust mode to allow VF to change its MAC address
in spite PF has set a forced MAC for that VF.

Whenever firmware indicates that there's an async indication it needs
to handle, there's a switch-case where the right functionality is called
based on function's personality and information.
Before iWARP is added [as yet another client], switch over the SPQ into
a callback-registered mechanism, allowing registration of the relevant
event-processing logic based on the function's personality. This allows
us to tidy the code by removing protocol-specifics from a common file.

VFs are currently not mapping their doorbell bar, instead relying
on the small doorbell window they have in their limited regview bar.
In order to increase the number of possible Tx connections [queues]
employeed by VF past 16, we need to start using the doorbell bar if
one such is exposed - VF would communicate this fact to PF which would
return the size-bar internally configured into chip, according to
which the VF would decide whether to actually utilize the doorbell
bar.

This adds the infrastructure for supporting VFs that want to open
multiple transmission queues on the same queue-zone.
At this point, there are no VFs that actually request this functionality,
but later patches would remedy that.
a. VF and PF would communicate the capability during ACQUIRE;
Legacy VFs would continue on behaving as they do today
b. PF would communicate number of supported CIDs to the VF
and would enforce said limitation
c. Whenever VF passes a request for a given queue configuration
it would also pass an associated index within said queue-zone

Until now we used to have a single VF legacy compatibility mode,
one that affected the place of the Rx producers of those VFs [mostly].
As PF would soon support allocating CIDs for VFs instead of having
a static CID<->queue configuration for them, we'll need to have
an additional legacy mode since existing VFs would need to continue
on using the older mode of operation.
Change the infrastrucutre so that the legacy would be able to indicate
which of the legacy behaviors is needed for a given VF.

When a queue-cid is allocated, assign an index inside that's
CID's queue-zone.
For PFs and VFS, this number is going to be unique and derive
from a per-queue-zone bitmap, while for PF's VFs queues the
number is currently going to constant; Later, we'd add the
capability of a VF to communicate such an index to its PF.

We're going to need additional information for queue-cids
that a PF creates for its VFs, so start by refactoring existing
logic used for initializing said struct into receiving a structure
encapsulating the VF-specific information that needs to be provided.
This also introduces QED_QUEUE_CID_SELF - each queue-cid would hold
an indication to whether it belongs to the hw-function holding it
[whether that's a PF or a VF], or else what's the VF id it belongs
to.

MSI-x table size of all child VFs of a given PF.
The existing code wouldn't cause the management firmware to set

size.

would set the number of MSI-x to be the maximum over the various
VFs' needs.

to configure anything for them, but that validation is done in various

When starting the VF's vport, the PF would first configure
the status blocks of the VF and then reset them.
That would cause some of the configured information to be lost -
specifically it would mean that all the VFs queues would use

When PF responds to the VF requests it also cleans the HW-channel
indication in firmware to allow further VF messages to arrive,
but the order currently applied is wrong -
The PF is copying by DMAE the response the VF is polling on for
completion, and only afterwards sets the HW-channel to ready state.
This creates a race condition where the VF would be able to send
an additional message to the PF before the channel would get ready
again, causing the firmware to consider the VF as malicious.

When a VF is considered malicious, driver handling of the VF
FLR flow would clean said indication - but not if the FLR is
part of an sriov-disable flow.
That leads to further issues, as PF wouldn't re-enable the
previously malicious VF when sriov is re-enabled.
No reason for that - simply clean malicious indications in
the sriov-disable flow as well.

A PF syncronizes all IOV activity relating to its VFs
by using a single workqueue handling the work.
The workqueue would reach a bitmask of pending VF events
and act upon each in turn.
Problem is that the indication of a VF message [which sets
the 'vf event' bit for that VF] arrives and is set in
the slowpath attention context, which isn't syncronized with
the processing of the events.
When multiple VFs are present, it's possible that PF would
lose the indication of one of the VF's pending evens, leading
that VF to later timeout.
Instead of adding locks/barriers, simply move from a bitmask
into a per-VF indication inside that VF entry in the PF database.

VF learns of the current link state via its bulletin board,
which might reflect either the physical link state or some
user-configured logical state.
Whenever the physical link changes or whnever such a configuration
is explicitly made by user the PF driver would update the bulletin
that the VF reads. But if neither has happened - i.e., PF still
hasn't got a physical link up and no additional configuration was
done the VF wouldn't have a valid link information available.
Simply reflect the physical link state whenever the VF is
initialized. The user could then affect it however he wants.

A step toward having qede agnostic to the queue configurations
in firmware/hardware - let the RSS indirections use queue handles
instead of actual queue indices.

Since the submission of the qedr driver, there's inconsistency
in the licensing of the various qed/qede files - some are GPLv2
and some are dual-license.
Since qedr requires dual-license and it's dependent on both,
we're updating the licensing of all qed/qede source files.

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.

Driver sets several restrictions about the number of supported VFs
according to available HW/FW resources.
This creates a problem as there are constellations which can't be
supported [as limitation don't accurately describe the resources],
as well as holes where enabling IOV would fail due to supposed
lack of resources.
This introduces a new interal feature - vf-queues, which would
be used to lift some of the restriction and accurately enumerate
the queues that can be used by a given PF's VFs.

Malicious VFs might be caught in several different methods:
- Misusing their bar permission and being blocked by hardware.
- Misusing their fastpath logic and being blocked by firmware.
- Misusing their interaction with their PF via hw-channel,
and being blocked by PF driver.
On the first two items, firmware would indicate to driver that
the VF is to be considered malicious, but would sometime still
allow the VF to communicate with the PF [depending on the exact
nature of the malicious activity done by the VF].
The current existing logic on the PF side lacks handling of such events,
and might allow the PF to perform some incorrect configuration on behalf
of a VF that was previously indicated as malicious.
The new scheme is simple -
Once the PF determines a VF is malicious it would:
a. Ignore any further requests on behalf of the VF-driver.
b. Prevent any configurations initiated by the hyperuser for
the malicious VF, as firmware isn't willing to serve such.
The malicious indication would be cleared upon the VF flr,
after which it would become usable once again.

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
so this patch marks these functions with 'static'.
