This patch adds mainly structures and APIs prototype changes
in order to give support for qede slowpath/fastpath support
for the same.

Yuval Mintz 944945986f qed: Introduce DMA_REGPAIR_LE
FW hsi contains regpairs, mostly for 64-bit address representations.
Since same paradigm is applied each time a regpair is filled, this
introduces a new utility macro for setting such regpairs.

Yuval Mintz 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.

Yuval Mintz fc48b7a614 qed/qede: use 8.7.3.0 FW.
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.

Conflicts:
	drivers/net/geneve.c

Here we had an overlapping change, where in 'net' the extraneous stats
bump was being removed whilst in 'net-next' the final argument to
udp_tunnel6_xmit_skb() was being changed.

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.

Tomer Tayar 4639d60d2b qed: Fix corner case for chain in-between pages
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,
and it can lead to a number of free elements which is higher by 1
than the actual value.

Sudarsana Kalluru 91420b83ba qed: Add support for changing LED state
Physical LEDs are being controlled by the management FW.
This adds the qed functionality required to request management FW to
change the LED configuration, as well as the necessary APIs for this
functionality to later be used by the protocol drivers.

Yuval Mintz cc875c2e4f qed: Add link support
Physical link is handled by the management Firmware.
This patch lays the infrastructure for attention handling in the driver,
as link change notifications arrive via async. attentions,
as well the handling of such notifications.

This patch also extends the API with the protocol drivers by adding
registered callbacks which the protocol driver passes to qed in order
to be notified of async. events originating from the FW/HW.

Yuval Mintz 25c089d78f qed: Add basic L2 interface
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].

Yuval Mintz 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.
