Address a link speed detection issue in KSZ886X PHY driver when in
forced link mode. Previously, link partners like "ASIX AX88772B"
with KSZ8873 could fall back to 10Mbit instead of configured 100Mbit.

The issue arises as KSZ886X PHY continues sending Fast Link Pulses (FLPs)
even with autonegotiation off, misleading link partners in autoneg mode,
leading to incorrect link speed detection.

Now, when autonegotiation is disabled, the driver sets the link state
forcefully using KSZ886X_CTRL_FORCE_LINK bit. This action, beyond just
disabling autonegotiation, makes the PHY state more reliably detected by
link partners using parallel detection, thus fixing the link speed
misconfiguration.

With autonegotiation enabled, link state is not forced, allowing proper
autonegotiation process participation.

====================
mlxsw: Move allocation of LAG table to the driver

PGT is an in-HW table that maps addresses to sets of ports. Then when some
HW process needs a set of ports as an argument, instead of embedding the
actual set in the dynamic configuration, what gets configured is the
address referencing the set. The HW then works with the appropriate PGT
entry.

Within the PGT is placed a LAG table. That is a contiguous block of PGT
memory where each entry describes which ports are members of the
corresponding LAG port.

The PGT is split to two parts: one managed by the FW, and one managed by
the driver. Historically, the FW part included also the LAG table, referred
to as FW LAG mode. Giving the responsibility for placement of the LAG table
to the driver, referred to as SW LAG mode, makes the whole system more
flexible. The FW currently supports both FW and SW LAG modes. To shed
complexity, the FW should in the future only support SW LAG mode.

Hence this patchset, where support for placement of LAG is added to mlxsw.

There are FW versions out there that do not support SW LAG mode, and on
Spectrum-1 in particular, there is no plan to support it at all. mlxsw will
therefore have to support both modes of operation.

Another aspect is that at least on Spectrum-1, there are FW versions out
there that claim to support driver-placed LAG table, but then reject or
ignore configurations enabling the same. The driver thus has to have a say
in whether an attempt to configure SW LAG mode should even be done.

The feature is therefore expressed in terms of "does the driver prefer SW
LAG mode?", and "what LAG mode the PCI module managed to configure the FW
with". This is unlike current flood mode configuration, where the driver
can give a strict value, and that's what gets configured. But it gives a
chance to the driver to determine whether LAG mode should be enabled at
all.

The "does the driver prefer SW LAG mode?" bit is expressed as a boolean
lag_mode_prefer_sw. The reason for this is largely another feature that
will be introduced in a follow-up patchset: support for CFF flood mode. The
driver currently requires that the FW be configured with what is called
controlled flood mode. But on capable systems, CFF would be preferred. So
there are two values in flight: the preferred flood mode, and the fallback.
This could be expressed with an array of flood modes ordered by preference,
but that looks like an overkill in comparison. This flag/value model is
then reused for LAG mode as well, except the fallback value is absent and
implied to be FW, because there are no other values to choose from.

The patchset progresses as follows:

- Patches #1 to #5 adjust reg.h and cmd.h with new register fields,
  constants and remarks.

- Patches #6 and #7 add the ability to request SW LAG mode and to query the
  LAG mode that was actually negotiated. This is where the abovementioned
  lag_mode_prefer_sw flag is added.

- Patches #7 to #9 generalize PGT allocations to make it possible to
  allocate the LAG table, which is done in patch #10.

- In patch #11, toggle lag_mode_prefer_sw on Spectrum-2 and above, which
  makes the newly-added code live.

On Spectrum-1, some FW versions claim to support lag_mode field despite
quietly ignoring any settings made to that field. Thus refrain from
attempting to configure lag_mode on those systems at all.

In this patch, if the LAG mode is SW, allocate the LAG table and configure
SGCR to indicate where it was allocated.

We use the default "DDD" (for dynamic data duplication) layout of the LAG
table. In the DDD mode, the membership information for each LAG is copied
in 8 PGT entries. This is done for performance reasons. The LAG table then
needs to be allocated on an address aligned to 8. Deal with this by
moving the LAG init ahead so that the LAG table is allocated at address 0.

PGT blocks are allocated through the function
mlxsw_sp_pgt_mid_alloc_range(). The interface assumes that the caller knows
which piece of PGT exactly they want to get. That was fine while the FID
code was the only client allocating blocks of PGT. However for SW-allocated
LAG table, there will be an additional client: mlxsw_sp_lag_init(). The
interface should therefore be changed to not require particular
coordinates, but to take just the requested size, allocate the block
wherever, and give back the PGT address.

In this patch, change the interface accordingly. Initialize FID family's
pgt_base from the result of the PGT allocation (note that mlxsw makes a
copy of the family structure, so what gets initialized is not actually the
global structure). Drop the now-unnecessary pgt_base initializations and
the corresponding defines.

We currently push everyone to use padding to align 64b values
in netlink. Un-padded nla_put_u64() doesn't even exist any more.

The story behind this possibly start with this thread:
https://lore.kernel.org/netdev/20121204.130914.1457976839967676240.davem@davemloft.net/
where DaveM was concerned about the alignment of a structure
containing 64b stats. If user space tries to access such struct
directly:

	struct some_stats *stats = nla_data(attr);
	printf("A: %llu", stats->a);

lack of alignment may become problematic for some architectures.
These days we most often put every single member in a separate
attribute, meaning that the code above would use a helper like
nla_get_u64(), which can deal with alignment internally.
Even for arches which don't have good unaligned access - access
aligned to 4B should be pretty efficient.
Kernel and well known libraries deal with unaligned input already.

Padded 64b is quite space-inefficient (64b + pad means at worst 16B
per attr vs 32b which takes 8B). It is also more typing:

    if (nla_put_u64_pad(rsp, NETDEV_A_SOMETHING_SOMETHING,
                        value, NETDEV_A_SOMETHING_PAD))

Create a new attribute type which will use 32 bits at netlink
level if value is small enough (probably most of the time?),
and (4B-aligned) 64 bits otherwise. Kernel API is just:

    if (nla_put_uint(rsp, NETDEV_A_SOMETHING_SOMETHING, value))

Calling this new type "just" sint / uint with no specific size
will hopefully also make people more comfortable with using it.
Currently telling people "don't use u8, you may need the bits,
and netlink will round up to 4B, anyway" is the #1 comment
we give to newcomers.

In terms of netlink layout it looks like this:

         0       4       8       12      16
32b:     [nlattr][ u32  ]
64b:     [  pad ][nlattr][     u64      ]

Retain error value in struct devlink_fmsg, to relieve drivers from
checking it after each call.
Note that fmsg is an in-memory builder/buffer of formatted message,
so it's not the case that half baked message was sent somewhere.

We could find following scheme in multiple drivers:
  err = devlink_fmsg_obj_nest_start(fmsg);
  if (err)
  	return err;
  err = devlink_fmsg_string_pair_put(fmsg, "src", src);
  if (err)
  	return err;
  err = devlink_fmsg_something(fmsg, foo, bar);
  if (err)
	return err;
  // and so on...
  err = devlink_fmsg_obj_nest_end(fmsg);

With retaining error API that translates to:
  devlink_fmsg_obj_nest_start(fmsg);
  devlink_fmsg_string_pair_put(fmsg, "src", src);
  devlink_fmsg_something(fmsg, foo, bar);
  // and so on...
  devlink_fmsg_obj_nest_end(fmsg);

What means we check error just when is time to send.

Possible error scenarios are developer error (API misuse) and memory
exhaustion, both cases are good candidates to choose readability
over fastest possible exit.

Note that this patch keeps returning errors, to allow per-driver conversion
to the new API, but those are not needed at this point already.

This commit itself is an illustration of benefits for the dev-user,
more of it will be in separate commits of the series.
