This pushes qed [and as result, all qed* drivers] into using 8.20.0.0
firmware. The changes are mostly contained in qed with minor changes
to qedi due to some HSI changes.

Content-wise, the firmware contains fixes to various issues exposed
since the release of the previous firmware, including:
 - Corrects iSCSI fast retransmit when data digest is enabled.
 - Stop draining packets when receiving several consecutive PFCs.
 - Prevent possible assertion when consecutively opening/closing
   many connections.
 - Prevent possible assertion due to too long BDQ fetch time.

In addition, the new firmware would allow us to later add iWARP support
in qed and qedr.

Management firmware is used as an arbiter between the various PFs
in matters of resources, but some of the resources that need to
be divided are dependent on the non-management firmware used,
so management firmware first needs to be told how many resources
there are before trying to divide them.

As part of the initialization sequence, driver would first inform
the management firmware of the available resources under
a dedicated resource lock, and afterwards request for various
resources which might be based on the previous set values.

Global locking can't properly be used to synchronize between different
PFs in all scenarios, as those instances might reside in different
logical partitions [e.g., when a PF is assigned via PDA to some VM].

The management firmware provides a generic infrastructure for
device locks. For each 'resource', it's guaranteed it could be acquired
by at most a single PF at any given time [or by management firmware].

This patch adds the necessary logic in qed for utilizing said
infrastructure, implementing lock/unlock internal APIs.

During HW initialization, driver would set various registers to their
needed values - but it assumes all registers start at their reset-value,
so there's no need to re-configure a register's default value.

This assumption might be incorrect, e.g., in case of preboot driver
running and initializing the driver prior to our driver.

To overcome this, we now ask management firmware to initiate a PF-flr
early during the initialization sequence. That would return everything
in the PF's scope back to default and prevent previous configurations
from still being applied.

Management firmware is used as an arbiter between the various PFs
in regard to loading - it causes the various PFs to load/unload
sequentially and informs each of its appropriate rule in the init.

But the existing flow is too weak to handle some scenarios where
PFs aren't properly cleaned prior to loading.
The significant scenarios falling under this criteria:
  a. Preboot drivers in some environment can't properly unload.
  b. Unexpected driver replacement [kdump, PDA].

Modern management firmware supports a more intricate loading flow,
where the driver has the ability to overcome previous limitations.
This moves qed into using this newer scheme.

Notice new scheme is backward compatible, so new drivers would
still be able to load properly on top of older management firmwares
and vice versa.

This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.

It also introduces a major 4-Cached SGE change in firmware, which can be

In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].

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
2edbff8d ("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.

 - Better blocking of malicious VFs.
 - After FLR, Tx-switching [internal routing] of packets might

 - Deletion of unicast MAC filters would sometime have side-effect

It also contains fixes for future qed* drivers that *hopefully* would be
