Currently RoCE v2 won't operate with RDMA CM due to missing setting of
the roce-flavour in the ll2 configuration.
This patch properly sets the flavour, and deletes incorrect HSI
that doesn't [yet] exist.

Driver uses a union for copying data to & from management firmware
when interacting with it.
Problem is that the function always copies sizeof(union) while commit
2edbff8dcb5d ("qed: Learn resources from management firmware") is casting
a union elements which is of smaller size [24-byte instead of 88-bytes].
Also, the union contains some inappropriate elements which increase its
size [should have been 32-bytes]. While this shouldn't corrupt other
PF messages to the MFW [as management firmware enforces permissions so
that each PF is allowed to write only to its own mailbox] we fix this
here as well.

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].

Today, RDMA capabilities are learned from management firmware
which provides a per-device indication for all interfaces.
Newer management firmware is capable of providing a per-device
indication [would later be extended to either RoCE/iWARP].
Try using this newer learning mechanism, but fallback in case
management firmware is too old to retain current functionality.

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.

This new firmware for the qed* adpaters fixes several issues:
- Better blocking of malicious VFs.
- After FLR, Tx-switching [internal routing] of packets might
be incorrect.
- 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.

The New QED firmware contains several fixes, including:
- Wrong classification of packets in 4-port devices.
- Anti-spoof interoperability with encapsulated packets.
- Tx-switching of encapsulated packets.
It also slightly improves Tx performance of the device.
In addition, this firmware contains the necessary logic for
supporting iscsi & rdma, for which we plan on pushing protocol
drivers in the imminent future.

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.

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.

BB_A0 is a development model that is will not reach actual clients.
In fact, future firmware would simply fail to initialize such chip.
This changes the configuration into B0 instead of A0, and adds a safeguard
against the slim chance someone would actually try this with an A0 adapter
in which case probe would gracefully fail.

This patch adds a public API for a network driver to work on top of QED.

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.
