The new firmware supports to divides the whole multicast MAC address space
equally to functions of all PFs, and calculates the space size of each PF
according to its function number.

To support this feature, PF driver adds querying multicast MAC address
space size from firmware and limits used number according to space size.

Currently, there are two ways for PF to set the unicast MAC address space
size: specified by config parameters in firmware or set to default value.

That's mean if the config parameters in firmware is zero, driver will
divide the whole unicast MAC address space equally to 8 PFs. However, in
this case, the unicast MAC address space will be wasted a lot when the
hardware actually has less then 8 PFs. And in the other hand, if one PF has
much more VFs than other PFs, then each function of this PF will has much
less address space than other PFs.

In order to ameliorate the above two situations, introduce the third way
of unicast MAC address space assignment: firmware divides the whole unicast
MAC address space equally to functions of all PFs, and calculates the space
size of each PF according to its function number. PF queries the space size
by the querying device specification command when in initialization
process.

The third way assignment is lower priority than specified by config
parameters, only if the config parameters is zero can be used, and if
firmware does not support the third way assignment, then driver still
divides the whole unicast MAC address space equally to 8 PFs.

Jiri says:

This patchset includes patches that prepare the driver to support modular
systems.

PLLP register is introduced to get front panel port label which is no
longer equivalent to "module + 1" for modular systems, where the
numbering is per line card.

So far for all systems all front panel ports had same format and could
be split to the same number of subports. This is no longer true for
modular systems, where every line card can have different types of front
panel ports.

The PMTDB register is introduced to easily query FW for split
capabilities of particular front panel port. It is generic for use in
modular and non-modular systems.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.

So, use the struct_size() helper to do the arithmetic instead of the
argument "size + count * size" in the kzalloc() function.
