Several user APIs can cause driver to perform an inner-reload.
Currently, doing this would cause the HW/FW statistics of the
adapter to reset, which isn't the expected behavior [statistics
should only reset on explicit unloads].

This patch adds the necessary driver support for Management Firmware to
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.

Device should be configured by default to VEB once VFs are active.
This changes the configuration of both PFs' and VFs' vports into enabling
tx-switching once sriov is enabled.

This adds support in 2 ndo that allow PF to tweak the VF's view of the
link - `ndo_set_vf_link_state' to allow it a view independent of the PF's,
and `ndo_set_vf_rate' which would allow the PF to limit the VF speed.

Allows the PF to enforce the VF's mac.
i.e., by using `ip link ... vf <x> mac <value>'.
While a MAC is forced, PF would prevent the VF from configuring any other
MAC.

This adds support for PF control over the VF vlan configuration.
I.e., `ip link ... vf <x> vlan <vid>' should now be supported.
1. <vid> != 0 => VF receives [unknowingly] only traffic tagged by
<vid> and tags all outgoing traffic sent by VF with <vid>.
2. <vid> == 0 ==> Remove the pvid configuration, reverting to previous.

While previous patches have already added the necessary logic to probe
VFs as well as enabling them in the HW, this patch adds the ability to
support VF FLR & SRIOV disable.
It then wraps both flows together into the first IOV callback to be
provided to the protocol driver - `configure'. This would later to be used
to enable and disable SRIOV in the adapter.

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.

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.

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.

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 patch moves the qed* driver into utilizing the 8.7.3.0 FW.
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.
V2:
- Fix kbuild test robot error/warnings.

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.

The amount of chain next pointer elements between the producer
and the consumer indices depends on which pages they currently
point to. The current calculation is based only on their difference,

as well the handling of such notifications.

This patch adds a public API for a network driver to work on top of QED.
The interface itself is very minimal - it's mostly infrastructure, as the
only content it has after this patch is a query for HW-based information
required for the creation of a network interface [I.e., no actual
protocol-specific configurations are supported].

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.
