Start reorganizing interface related data structures toward

We'll use bss_conf for per-link configuration later, so

In order to support multi-link operation with multiple links,
start adding some APIs. The notable addition here is to have
the link ID in a new nl80211 attribute, that will be used to
differentiate the links in many nl80211 operations.
So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID
attribute (as well as the NL80211_ATTR_MLO_LINKS attribute)
and plugs it through the system in some places, checking the
validity etc. along with other infrastructure needed for it.
For now, I've decided to include only the over-the-air link
ID in the API. I know we discussed that we eventually need to
have to have other ways of identifying a link, but for local
AP mode and auth/assoc commands as well as set_key etc. we'll
use the OTA ID.
Also included in this patch is some refactoring of the data
structures in struct wireless_dev, splitting for the first
time the data into type dependent pieces, to make reasoning
about these things easier.

We don't really care too much right now since our data
structures are set up to not have a problem with this,
but clearly it's wrong to accept WEP and pairwise keys
with key ID > 3.
However, with MLD we need to split into per-link (GTK,
IGTK, BIGTK) and per interface/MLD (including WEP) keys
so make sure this is not a problem.

net: ipa: simplify completion statistics
The first patch in this series makes the name used for variables
representing a TRE ring be consistent everywhere. The second
renames two structure fields to better represent their purpose.
The last four rework a little code that manages some tranaction and
byte transfer statistics maintained mainly for TX endpoints. For
the most part this series is refactoring. The last one also
includes the first step toward no longer assuming an event ring is
dedicated to a single channel.

In gsi_evt_ring_rx_update(), we update each transaction so its len
field reflects the actual number of bytes received. In the process,
the total number of transactions and bytes processed on the channel
are summed, and added to a running total for the channel.
But we don't actually use those running totals for RX endpoints.
They're maintained for TX channels to support CoDel when they are
associated with a "real" network device.
So stop maintaining these totals for RX endpoints, and update the
comment where the fields are defined to make it clear they're only
valid for TX channels.

When a TX request is issued, its channel's accumulated byte and
transaction counts are recorded. This currently does *not* take
into account the transaction being committed.
Later, when the transaction completes, the number of bytes and
transactions that have completed since the transaction was committed
are reported to the network stack. The transaction and its byte
count are accounted for at that time.
Instead, record the transaction and its bytes in the counts recorded
at commit time. This avoids the need to do so when the transaction
completes, and provides a (small) simplification of that code.

There are two fields in a GSI transaction that keep track of TRE
counts. The first represents the number of TREs reserved for the
transaction in the TRE ring; that's currently named "tre_count".
The second is the number of TREs that are actually *used* by the
transaction at the time it is committed.
Rename the "tre_count" field to be "rsvd_count", to make its meaning
a little more specific. The "_count" is present in the name mainly
to avoid interpreting it as a reserved (not-to-be-used) field. This
name also distinguishes it from the "tre_count" field associated
with a channel.
Rename the "used" field to be "used_count", to match the convention
used for reserved TREs.

Support mt7531 on BPI-R2 Pro
This Series add Support for the mt7531 switch on Bananapi R2 Pro board.
This board uses port5 of the switch to conect to the gmac0 of the
rk3568 SoC.
Currently CPU-Port is hardcoded in the mt7530 driver to port 6.
Compared to v1 the reset-Patch was dropped as it was not needed and
CPU-Port-changes are completely rewriten based on suggestions/code from
Vladimir Oltean (many thanks to this).
In DTS Patch i only dropped the status-property that was not
needed/ignored by driver.
Due to the Changes i also made a regression test on mt7623 bpi-r2
(mt7623 soc + mt7530) and bpi-r64 (mt7622 soc + mt7531) with cpu-
port 6. Tests were done directly (ipv4 config on dsa user port)
and with vlan-aware bridge including vlan that was tagged outgoing
on dsa user port.

A board may have no independent reset-line, so reset cannot be used
inside switch driver.
E.g. on Bananapi-R2 Pro switch and gmac are connected to same reset-line.
Resets should be acquired only to 1 device/driver. This prevents reset to
be bound to switch-driver if reset is already used for gmac. If reset is
only used by switch driver it resets the switch *and* the gmac after the
mdio bus comes up resulting in mdio bus goes down. It takes some time
until all is up again, switch driver tries to read from mdio, will fail
and defer the probe. On next try the reset does the same again.
Make reset optional for such boards.
Allow port 5 as cpu-port and phy-mode rgmii for mt7531.
- MT7530 supports RGMII on port 5 and RGMII/TRGMII on port 6.
- MT7531 supports on port 5 RGMII and SGMII (dual-sgmii) and
SGMII on port 6.

Rework vlan_add/vlan_del functions in preparation for dynamic cpu port.
Currently BIT(MT7530_CPU_PORT) is added to new_members, even though
mt7530_port_vlan_add() will be called on the CPU port too.
Let DSA core decide when to call port_vlan_add for the CPU port, rather
than doing it implicitly.
We can do autonomous forwarding in a certain VLAN, but not add br0 to that
VLAN and avoid flooding the CPU with those packets, if software knows it
doesn't need to process them.

====================
mlxsw: Remove XM support
The XM was supposed to be an external device connected to the
Spectrum-{2,3} ASICs using dedicated Ethernet ports. Its purpose was to
increase the number of routes that can be offloaded to hardware. This was
achieved by having the ASIC act as a cache that refers cache misses to the
XM where the FIB is stored and LPM lookup is performed.
Testing was done over an emulator and dedicated setups in the lab, but
the product was discontinued before shipping to customers.
Therefore, in order to remove dead code and reduce complexity of the
code base, revert the three patchsets that added XM support.

Leon Says
=========
SW steering manipulates packet's header using "modifying header" actions.
Many of these actions do the same operation, but use different data each time.
Currently we create and keep every one of these actions, which use expensive
and limited resources.
Now we introduce a new mechanism - pattern and argument, which splits
a modifying action into two parts:
1. action pattern: contains the operations to be applied on packet's header,
mainly set/add/copy of fields in the packet
2. action data/argument: contains the data to be used by each operation
in the pattern.
This way we reuse same patterns with different arguments to create new
modifying actions, and since many actions share the same operations, we end
up creating a small number of patterns that we keep in a dedicated cache.
These modify header patterns are implemented as new type of ICM memory,
so the following kernel patch series add the support for this new ICM type.
==========

Fix the implementation of ethtool_convert_link_mode_to_legacy_u32(), which
is supposed to return false if src has bits higher than 31 set. The current
implementation uses the complement of bitmap_fill(ext, 32) to test high
bits of src, which is wrong as bitmap_fill() fills _with long granularity_,
and sizeof(long) can be > 4. No users of this function currently check the
return value, so the bug was dormant.
Also remove the check for __ETHTOOL_LINK_MODE_MASK_NBITS > 32, as the enum
ethtool_link_mode_bit_indices contains far beyond 32 values. Using
find_next_bit() to test the src bitmask works regardless of this anyway.

This doesn't have any functional change, since, at this point,
