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.

The current FID mode has one place where PGT address can be stored: the FID

allocating a block per FID flood table, to allocating a block per FID
family.

Do just that in this patch.

The per-family allocation is going to be useful for another related feature
as well: the CFF mode.

lag_mode describes where the responsibility for LAG table placement lies:

Therefore add a bus callback to determine the configured LAG mode. Also add
to core an API to query it.

netlink: add variable-length / auto integers

Add netlink support for "common" / variable-length / auto integers
which are carried at the message level as either 4B or 8B depending
on the exact value. This saves space and will hopefully decrease
the number of instances where we realize that we needed more bits
after uAPI is set is stone. It also loosens the alignment requirements,
avoiding the need for padding.

This mini-series is a fuller version of the previous RFC:

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.

Extend the support to full range of min/max checks.
None of the existing YNL families required complex integer validation.

The support is less than trivial, because we try to keep struct nla_policy
tiny the min/max members it holds in place are s16. Meaning we can only
express checks in range of s16. For larger ranges we need to define
a structure and link it in the policy.

====================
mptcp: Fixes for v6.6

Patch 1 corrects the logic for MP_JOIN tests where 0 RSTs are expected.

Patch 2 ensures MPTCP packets are not incorrectly coalesced in the TCP
backlog queue.

Patch 3 avoids a zero-window probe and associated WARN_ON_ONCE() in an
expected MPTCP reinjection scenario.

Patches 4 & 5 allow an initial MPTCP subflow to be closed cleanly
instead of always sending RST. Associated selftest is updated.
