b8a0d83fe4 wifi: ath12k: move firmware stats out of debugfs
Currently, firmware stats, comprising pdev, vdev and beacon stats are
part of debugfs. In firmware pdev stats, firmware reports the final
Tx power used to transmit each packet. If driver wants to know the
final Tx power being used at firmware level, it can leverage from
firmware pdev stats.

Move firmware stats out of debugfs context in order to leverage
the final Tx power reported in it even when debugfs is disabled.

d1e879ec60 wifi: iwlwifi: add iwlmld sub-driver
iwlwifi is the driver of all Intel wifi devices since 2008.
Since then, the hardware has changed a lot, but the firmware
API has changed even more. The need to keep one driver that
supports all those different APIs led us to introduce a new
architecture circa 2012 which allowed us to keep the same
interface to the hardware (DMAs, Tx queues, etc...) with a
new layer to implement the mid-layer between mac80211 and
the firmware. The first component is called the 'transport'
and the latter is called 'operation_mode' a.k.a  op_mode.

In 2013 we took advantage of the new architecture to
introduce iwlmvm which allowed us to implement the, then,
new firmware API. This op_mode supports 7260 and up, those
devices supports support at least VHT.

Since then, wifi evolved and so did the firmware. It became
much bigger and took a lot of functionality from the driver.
It became increasingly hard to keep the same op_mode for the
newest devices and we experienced frequent regressions on
older devices. In order to avoid those regressions and keep
the code maintainable, we decided it was about time to start
a new op_mode.

iwlmld is a new op_mode that supports BE200 or newer if the
firmware being used is 97.ucode or newer. If the user has
an older devices or BE200 with .96.ucode, iwlmvm will be
loaded. Of course, this op_mode selection is seamless.

All the features supported in iwlmvm are supported in
iwlmld besides a few seldom used use cases: injection and
Hotspot 2.0. Those are under work.

A few points about the implementation:
 * iwlmld doesn't have any mutexes, it relies on the
   wiphy_lock
 * iwlmld is more "resource oriented": stations, links and
   interfaces are allocated and freed only after all the
   relevant flows are completed.
 * Firmware notifications' sizes are validated in a more
   structured way.

We would love to see this new op_mode merged in 6.15. The
firmware for this new driver (.97.ucode) is not yet publicly
available but it'll be sent very soon.
People eager to get an early version of this firmware can
contact Emmanuel at:
emmanuel.grumbach@intel.com

I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.

5b62996184 Merge branch 'netconsole-add-taskname-sysdata-support'
Breno Leitao says:

====================
netconsole: Add taskname sysdata support

This patchset introduces a new feature to the netconsole extradata
subsystem that enables the inclusion of the current task's name in the
sysdata output of netconsole messages.

This enhancement is particularly valuable for large-scale deployments,
such as Meta's, where netconsole collects messages from millions of
servers and stores them in a data warehouse for analysis. Engineers
often rely on these messages to investigate issues and assess kernel
health.

One common challenge we face is determining the context in which
a particular message was generated. By including the task name
(task->comm) with each message, this feature provides a direct answer to
the frequently asked question: "What was running when this message was
generated?"

This added context will significantly improve our ability to diagnose
and troubleshoot issues, making it easier to interpret output of
netconsole.

The patchset consists of seven patches that implement the following changes:

 * Refactor CPU number formatting into a separate function
 * Prefix CPU_NR sysdata feature with SYSDATA_
 * Patch to covert a bitwise operation into boolean
 * Add configfs controls for taskname sysdata feature
 * Add taskname to extradata entry count
 * Add support for including task name in netconsole's extra data output
 * Document the task name feature in Documentation/networking/netconsole.rst
 * Add test coverage for the task name feature to the existing sysdata selftest script

These changes allow users to enable or disable the task name feature via
configfs and provide additional context for kernel messages by showing
which task generated each console message.

I have tested these patches on some servers and they seem to work as
expected.

  - Task names are included when the feature is enabled
  - Task names are excluded when the feature is disabled
  - The feature works correctly alongside other sysdata fields like CPU

dd30ae5332 netconsole: add task name to extra data fields
This is the core patch for this whole patchset. Add support for
including the current task's name in netconsole's extra data output.
This adds a new append_taskname() function that writes the task name
(from current->comm) into the target's extradata buffer, similar to how
CPU numbers are handled.

The task name is included when the SYSDATA_TASKNAME field is set,
appearing in the format "taskname=<name>" in the output. This additional
context can help with debugging by showing which task generated each
console message.

In addition, MAC link failure detection is added.
If the MAC link fails after core_reset, driver invokes

Due to phydev->lock, re-link cannot be triggered

====================
Introduce flowtable hw offloading in airoha_eth driver

Introduce netfilter flowtable integration in airoha_eth driver to
offload 5-tuple flower rules learned by the PPE module if the user
accelerates them using a nft configuration similar to the one reported
below:

table inet filter {
	flowtable ft {
		hook ingress priority filter
		devices = { lan1, lan2, lan3, lan4, eth1 }
		flags offload;
	}
	chain forward {
		type filter hook forward priority filter; policy accept;
		meta l4proto { tcp, udp } flow add @ft
	}
}

Packet Processor Engine (PPE) module available on EN7581 SoC populates
the PPE table with 5-tuples flower rules learned from traffic forwarded
between the GDM ports connected to the Packet Switch Engine (PSE) module.
airoha_eth driver configures and collects data from the PPE module via a
Network Processor Unit (NPU) RISC-V module available on the EN7581 SoC.
Move airoha_eth driver in a dedicated folder
(drivers/net/ethernet/airoha).

In the current codebase airoha_eth driver supports just a single
net_device connected to the Packet Switch Engine (PSE) lan port (GDM1).
As shown in commit 23020f0493 ("net: airoha: Introduce ethernet
support for EN7581 SoC"), PSE can switch packets between four GDM ports.
Enable the capability to create a net_device for each GDM port of the
PSE module. Moreover, since the QDMA blocks can be shared between
net_devices, do not stop TX/RX DMA in airoha_dev_stop() if there are
active net_devices for this QDMA block.

Peter Seiderer says:

====================
Some pktgen fixes/improvments (part II)

While taking a look at '[PATCH net] pktgen: Avoid out-of-range in
get_imix_entries' ([1]) and '[PATCH net v2] pktgen: Avoid out-of-bounds
access in get_imix_entries' ([2], [3]) and doing some tests and code review
I detected that the /proc/net/pktgen/... parsing logic does not honour the
user given buffer bounds (resulting in out-of-bounds access).

This can be observed e.g. by the following simple test (sometimes the
old/'longer' previous value is re-read from the buffer):

        $ echo add_device lo@0 > /proc/net/pktgen/kpktgend_0

        $ echo "min_pkt_size 12345" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0
Params: count 1000  min_pkt_size: 12345  max_pkt_size: 0
Result: OK: min_pkt_size=12345

        $ echo -n "min_pkt_size 123" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0
Params: count 1000  min_pkt_size: 12345  max_pkt_size: 0
Result: OK: min_pkt_size=12345

        $ echo "min_pkt_size 123" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0
Params: count 1000  min_pkt_size: 123  max_pkt_size: 0
Result: OK: min_pkt_size=123

So fix the out-of-bounds access (and some minor findings) and add a simple
proc_net_pktgen selftest...

Patch set splited into part I (now already applied to net-next)

- net: pktgen: replace ENOTSUPP with EOPNOTSUPP
- net: pktgen: enable 'param=value' parsing
- net: pktgen: fix hex32_arg parsing for short reads
- net: pktgen: fix 'rate 0' error handling (return -EINVAL)
- net: pktgen: fix 'ratep 0' error handling (return -EINVAL)
- net: pktgen: fix ctrl interface command parsing
- net: pktgen: fix access outside of user given buffer in pktgen_thread_write()

nd part II (this one):

- net: pktgen: use defines for the various dec/hex number parsing digits lengths
- net: pktgen: fix mix of int/long
- net: pktgen: remove extra tmp variable (re-use len instead)
- net: pktgen: remove some superfluous variable initializing
- net: pktgen: fix mpls maximum labels list parsing
