Align the driver feature distribution with the flow utilized
by the management firmware - first reserve L2 queues for
VFs and use all the remaining for the PF.
The current distribution might lead to PFs with an enormous
amount of queues, but at the same time leave us with insufficient
resources for starting all VFs.

Management firmware and driver are meant to be both backward and forward
compatibile with each other.
If a new mangement firmware would work with an older driver,
it's possible that driver would receive indications which are meaningless
to it. That's perfectly acceptible from the firmware part - so no need to
log such messages at default verbosity; That would only serve to confuse
users.

The management firmware is running on a Big Endian processor,
and when running on LE platform HW is configured to swap access
to memory shared between management firmware and driver on
32-bit granulariy.
As a result, for matters of simplicity most of the APIs between
driver and management firmware are based on 32-bit variables.
MAC settings are one exception, as driver needs to fill a byte
array when indicating to management firmware that primary MAC
has changed.
Due to the swap, driver must make sure that the mac that was
provided in byte-order would be translated into native order,
otherwise after the swap the management firmware would read
it swapped.

The driver interaction with management firmware involves a union
of all the data-members relating to the commands the driver prepares.
Current interface assumes the caller always passes such a union -
but thats cumbersome as well as risky [chancing a stack corruption
in case caller accidentally passes a smaller member instead of union].
Change implementation so that caller could pass a pointer to any
of the members instead of the union.

Interaction of driver -> management firmware is based
on a one-pending mailbox [per interface], and various
mailbox commands need to be synchronized.
Current scheme is messy, and there's a difficulty extending
it as it deals differently with various commands as well as
making assumption on the required behavior for load/unload
requests.
Drop the current scheme into a completion-list-based approach;
Each flow would try sending the command when possible,
allowing one flow to complete another flow's completion and
relieve the mailbox before sending its own command.

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.

so qed releases the spinlock and re-claims it afterwards.
Problem is that the final spin_lock_irqrestore() at the end

initial irqsave() instead of the flags from the most recent
irqsave(). So it's possible that the interrupt status would
be incorrect at the end of the processing.

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.

Driver changes the link properties via communication with
the management firmware, and re-reads the resulting link status
when it receives an indication that the link has changed.
However, there are certain scenarios where such indications
might be missing, and so driver also re-reads the current link
results without attention in several places. Specifically, it
does so during load and when resetting the link.
This creates a race where driver might reflect incorrect
link status - e.g., when explicit reading of the link status is
switched by attention with the changed configuration.
Correct this flow by a lock syncronizing the handling of the
link indications [both explicit requests and attention].

Flows accessing registers require the flow to hold a PTT entry.
To protect 'major' load/unload flows a main_ptt is pre-allocated
to guarantee such flows wouldn't be blocked by PTT being
unavailable.
Status block initialization currently uses the main_ptt which
is incorrect, as this flow might run concurrently to others
[E.g., loading qedr while toggling qede]. That would have dire
effects as it means registers' access to device breaks and further
read/writes might access incorrect addresses.
Instead, when initializing status blocks acquire/release a PTT

is explicitly made by user the PF driver would update the bulletin

hasn't got a physical link up and no additional configuration was
done the VF wouldn't have a valid link information available.
