Use ethtool_sprintf/puts() helper functions which handle the common
pattern of printing a string into the ethtool strings interface and
incrementing the string pointer by ETH_GSTRING_LEN.
The int return value in mlx5e_self_test_fill_strings() is not removed as
it is still used to return the number of selftests.

====================
wireless-next patches for v6.10
The first "new features" pull request for v6.10 with changes both in
stack and in drivers. The big thing in this pull request is that
wireless subsystem is now almost free of sparse warnings. There's only
one warning left in ath11k which was introduced in v6.9-rc1 and will
be fixed via the wireless tree.
Realtek drivers continue to improve, now we have support for RTL8922AE
and RTL8723CS devices. ath11k also has long waited support for P2P.
This time we have a small conflict in iwlwifi, Stephen has an example
merge resolution which should help with fixing the conflict:
https://lore.kernel.org/all/20240326100945.765b8caf@canb.auug.org.au/

ethtool.py depends on yml files in a specific location of the linux kernel

Some PHYs can recognize during a cable test if the impedance in the cable
is okay. They can detect reflections caused by impedance discontinuity
between a regular 100 Ohm cable and an abnormal part with a higher or
lower impedance.
This commit introduces a new result code:
ETHTOOL_A_CABLE_RESULT_CODE_IMPEDANCE_MISMATCH,
which represents the results of a cable test indicating issues with
impedance integrity.

This is a follow-up series for commit 4090fa373f0e ("af_unix: Replace

In the previous GC implementation, the shape of the inflight socket
graph was not expected to change while GC was in progress.
MSG_PEEK was tricky because it could install inflight fd silently
and transform the graph.
Let's say we peeked a fd, which was a listening socket, and accept()ed
some embryo sockets from it. The garbage collection algorithm would
have been confused because the set of sockets visited in scan_inflight()
would change within the same GC invocation.
That's why we placed spin_lock(&unix_gc_lock) and spin_unlock() in
unix_peek_fds() with a fat comment.
In the new GC implementation, we no longer garbage-collect the socket
if it exists in another queue, that is, if it has a bridge to another
SCC. Also, accept() will require the lock if it has edges.
Thus, we need not do the complicated lock dance.

When we passed fds, we used to bump each file's refcount twice
in scm_fp_copy() and scm_fp_dup() before linking the socket to
gc_inflight_list.
This is because we incremented the inflight count of the socket
and linked it to the list in advance before passing skb to the
destination socket.
Otherwise, the inflight socket could have been garbage-collected
in a small race window between linking the socket to the list and
queuing skb:
CPU 1 : sendmsg(X) w/ A's fd CPU 2 : close(A)
----- -----
/* Here A's refcount is 1, and inflight count is 0 */
bump A's refcount to 2 in scm_fp_copy()
bump A's inflight count to 1
link A to gc_inflight_list
decrement A's refcount to 1
/* A's refcount == inflight count, thus A could be GC candidate */
start GC
mark A as candidate
purge A's receive queue
queue skb w/ A's fd to X
/* A is queued, but all data has been lost */
After commit 4090fa373f0e ("af_unix: Replace garbage collection
algorithm."), we increment the inflight count and link the socket
to the global list only when queuing the skb.
The race no longer exists, so let's not clone the fd nor bump
the count in unix_attach_fds().

Prior to this patch, what we can see by enabling trace_tcp_send is
only happening under two circumstances:
1) active rst mode
2) non-active rst mode and based on the full socket
That means the inconsistency occurs if we use tcpdump and trace
simultaneously to see how rst happens.
It's necessary that we should take into other cases into considerations,
say:
1) time-wait socket
2) no socket
...
By parsing the incoming skb and reversing its 4-tuple can
we know the exact 'flow' which might not exist.
Samples after applied this patch:
1. tcp_send_reset: skbaddr=XXX skaddr=XXX src=ip:port dest=ip:port
state=TCP_ESTABLISHED
2. tcp_send_reset: skbaddr=000...000 skaddr=XXX src=ip:port dest=ip:port
state=UNKNOWN
Note:
1) UNKNOWN means we cannot extract the right information from skb.
2) skbaddr/skaddr could be 0

For systems that use CPU isolation (via nohz_full), creating or destroying
a socket with SO_TIMESTAMP, SO_TIMESTAMPNS or SO_TIMESTAMPING with flag
SOF_TIMESTAMPING_RX_SOFTWARE will cause a static key to be enabled/disabled.
This in turn causes undesired IPIs to isolated CPUs.
So enable the static key unconditionally, if CPU isolation is enabled,
thus avoiding the IPIs.

Fulfill the requirement that for GQI, the number of pages per
RX QPL is equal to the ring size. Set this value to be equal to
ring size. Because of this change, the rx_data_slot_cnt and
rx_pages_per_qpl fields stored in the priv structure are not
needed, so remove their usage. And for DQO, the number of pages
per RX QPL is more than ring size to account for out-of-order
completions. So set it to two times of rx ring size.

For the DQO queue format, the gve driver stores two ring sizes
for both TX and RX - one for completion queue ring and one for
data buffer ring. This is supposed to enable asymmetric sizes
for these two rings but that is not supported. Make both fields
reference the same single variable.
This change renders reading supported TX completion ring size
and RX buffer ring size for DQO from the device useless, so change
those fields to reserved and remove related code.

Combine the gve_set_desc_cnt and gve_set_desc_cnt_dqo into
one function which sets the counts after checking the queue
format. Both the functions in the previous code and the new
combined function never return an error so make the new
function void and remove the goto on error.
Also rename the new function to gve_set_default_desc_cnt to
be clearer about its intention.

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally.
There are currently a couple of objects in `struct smc_clc_msg_proposal_area`
that contain a couple of flexible structures:
struct smc_clc_msg_proposal_area {
...
struct smc_clc_v2_extension pclc_v2_ext;
...
struct smc_clc_smcd_v2_extension pclc_smcd_v2_ext;
...
};
So, in order to avoid ending up with a couple of flexible-array members
in the middle of a struct, we use the `struct_group_tagged()` helper to
separate the flexible array from the rest of the members in the flexible
structure:
struct smc_clc_smcd_v2_extension {
struct_group_tagged(smc_clc_smcd_v2_extension_fixed, fixed,
u8 system_eid[SMC_MAX_EID_LEN];
u8 reserved[16];
);
struct smc_clc_smcd_gid_chid gidchid[];
};
With the change described above, we now declare objects of the type of
the tagged struct without embedding flexible arrays in the middle of
another struct:
struct smc_clc_msg_proposal_area {
...
struct smc_clc_v2_extension_fixed pclc_v2_ext;
...
struct smc_clc_smcd_v2_extension_fixed pclc_smcd_v2_ext;
...
};
We also use `container_of()` when we need to retrieve a pointer to the
flexible structures.
So, with these changes, fix the following warnings:
In file included from net/smc/af_smc.c:42:
net/smc/smc_clc.h:186:49: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

Similar with commit 08d323234d10 ("net: fou: rename the source for linking"),
We'll need to link two objects together to form the team module.
This means the source can't be called team, the build system expects
team.o to be the combined object.

Since commit 099ecf59f05b ("net: annotate lockless accesses to
sk->sk_max_ack_backlog") decided to handle the sk_max_ack_backlog
locklessly, there is one more function mostly called in TCP/DCCP
cases. So this patch completes it:)

UTILITY_NAME_LENGTH is 16. So better use the former when defining the
'utility_name' array. This makes the intent clearer when it is used around
line 260.
While at it, declare variable in reverse xmas tree style.

For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask
variable on stack is not recommended since it can cause potential stack
overflow.
Instead, kernel code should always use *cpumask_var API(s) to allocate
cpumask var in config-neutral way, leaving allocation strategy to
CONFIG_CPUMASK_OFFSTACK.
Use *cpumask_var API(s) to address it.

The bindings for Renesas Ethernet TSN was just merged in v6.9 and the
design for the bindings followed that of other Renesas Ethernet drivers
and thus did not force a child-node for the MDIO bus. As there
are no upstream drivers or users of this binding yet take the
opportunity to correct this and force the usage of a child-node for the
MDIO bus.

Alexander Lobakin says:
====================
page_pool: allow direct bulk recycling
Previously, there was no reliable way to check whether it's safe to use
direct PP cache. The drivers were passing @allow_direct to the PP
recycling functions and that was it. Bulk recycling is used by
xdp_return_frame_bulk() on .ndo_xdp_xmit() frames completion where
the page origin is unknown, thus the direct recycling has never been
tried.
Now that we have at least 2 ways of checking if we're allowed to perform
direct recycling -- pool->p.napi (Jakub) and pool->cpuid (Lorenzo), we
can use them when doing bulk recycling as well. Just move that logic
from the skb core to the PP core and call it before
__page_pool_put_page() every time @allow_direct is false.
Under high .ndo_xdp_xmit() traffic load, the win is 2-3% Pps assuming
the sending driver uses xdp_return_frame_bulk() on Tx completion.

Now that the checks for direct recycling possibility live inside the
Page Pool core, reuse them when performing bulk recycling.
page_pool_put_page_bulk() can be called from process context as well,
page_pool_napi_local() takes care of this at the very beginning.
Under high .ndo_xdp_xmit() traffic load, the win is 2-3% Pps assuming
the sending driver uses xdp_return_frame_bulk() on Tx completion.
