This aligns some parameters with vendor driver r8125/r8126 to avoid
compatibility issues. Note that for RTL8125B there's no functional
change, just the open-coded version of the function is replaced.

net_dim() is currently passed a struct dim_sample argument by value.
struct dim_sample is 24 bytes. Since this is greater 16 bytes, x86-64
passes it on the stack. All callers have already initialized dim_sample
on the stack, so passing it by value requires pushing a duplicated copy
to the stack. Either witing to the stack and immediately reading it, or
perhaps dereferencing addresses relative to the stack pointer in a chain
of push instructions, seems to perform quite poorly.
In a heavy TCP workload, mlx5e_handle_rx_dim() consumes 3% of CPU time,
94% of which is attributed to the first push instruction to copy
dim_sample on the stack for the call to net_dim():
// Call ktime_get()
0.26 |4ead2: call 4ead7 <mlx5e_handle_rx_dim+0x47>
// Pass the address of struct dim in %rdi
|4ead7: lea 0x3d0(%rbx),%rdi
// Set dim_sample.pkt_ctr
|4eade: mov %r13d,0x8(%rsp)
// Set dim_sample.byte_ctr
|4eae3: mov %r12d,0xc(%rsp)
// Set dim_sample.event_ctr
0.15 |4eae8: mov %bp,0x10(%rsp)
// Duplicate dim_sample on the stack
94.16 |4eaed: push 0x10(%rsp)
2.79 |4eaf1: push 0x10(%rsp)
0.07 |4eaf5: push %rax
// Call net_dim()
0.21 |4eaf6: call 4eafb <mlx5e_handle_rx_dim+0x6b>
To allow the caller to reuse the struct dim_sample already on the stack,
pass the struct dim_sample by reference to net_dim().

Under CONFIG_PROVE_RCU_LIST + CONFIG_RCU_EXPERT
hlist_for_each_entry_rcu() provides very helpful splats, which help
to find possible issues. I missed CONFIG_RCU_EXPERT=y in my testing
config the same as described in
a3e4bf7f9675 ("configs/debug: make sure PROVE_RCU_LIST=y takes effect").
The fix itself is trivial: add the very same lockdep annotations
as were used to dereference ao_info from the socket.

2. Writing a known value to the key
3. Validating the key-value pair appears in the captured network output

UAPI: net/ethtool: Avoid thousands of -Wflex-array-member-not-at-end warnings
Small patch series aimed at fixing thousands of -Wflex-array-member-not-at-end
warnings by creating a new tagged struct within a flexible structure. We then
use this new struct type to fix problematic middle-flex-array declarations in
multiple composite structs, as well as to update the type of some variables in
various functions.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Change the type of the middle struct member currently causing trouble from
`struct ethtool_link_settings` to `struct ethtool_link_settings_hdr`.
Additionally, update the type of some variables in various functions that
don't access the flexible-array member, changing them to the newly created
`struct ethtool_link_settings_hdr`. These changes are needed because the
type of the conflicting middle members changed. So, those instances that
expect the type to be `struct ethtool_link_settings` should be adjusted to
the newly created type `struct ethtool_link_settings_hdr`.
Also, adjust variable declarations to follow the reverse xmas tree
convention.
Fix 3338 of the following -Wflex-array-member-not-at-end warnings:

Use the `__struct_group()` helper to create a new tagged
`struct ethtool_link_settings_hdr`. This structure groups together
all the members of the flexible `struct ethtool_link_settings`
except the flexible array. As a result, the array is effectively
separated from the rest of the members without modifying the memory
layout of the flexible structure.
This new tagged struct will be used to fix problematic declarations
of middle-flex-arrays in composite structs[1].

We previously hooked the tcp_drop_reason() function using BPF to monitor
TCP drop reasons. However, after upgrading our compiler from GCC 9 to GCC
11, tcp_drop_reason() is now inlined, preventing us from hooking into it.
To address this, it would be beneficial to make noinline explicitly for
tracing.

Kernel functions that are not inlined can be easily hooked with BPF for
tracing. However, functions intended for tracing may still be inlined
unexpectedly. For example, in our case, after upgrading the compiler from
GCC 9 to GCC 11, the tcp_drop_reason() function was inlined, which broke
our monitoring tools. To prevent this, we need to ensure that the function
remains non-inlined.
The noinline_for_tracing annotation is introduced as a general solution for
preventing inlining of kernel functions that need to be traced. This
approach avoids the need for adding individual noinline comments to each
function and provides a more consistent way to maintain traceability.

dpll op and fill-up the quality level value properly.

In order to allow driver expose quality level of the clock it is
running, introduce a new netlink attr with enum to carry it to the
userspace. Also, introduce an op the dpll netlink code calls into the
driver to obtain the value.

In the error path of netlink_proto_init(), frees the already allocated
bucket table for new hash tables in a loop, but it is going to panic,
so it is not necessary to clean up the resources, just remove the
dead code.

```
readonly STATS="$(mktemp -p /tmp ns-XXXXXX)"
readonly BASE=`basename $STATS`
```
It could be a mistake to write to $BASE rather than $STATS, where $STATS
is used to save the NSTAT_HISTORY and it will be cleaned up before exit.
Although since we've been creating the wrong file this whole time and
everything worked, it's fine to remove these 2 lines completely

dql->last_obj_cnt is read/written from different contexts,
without any lock synchronization.
Use READ_ONCE()/WRITE_ONCE() to avoid load/store tearing.
