-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct iwl_tx_cmd_hdr`. This structure
groups together all the members of the flexible `struct iwl_tx_cmd`
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.
We then change the type of the middle struct members currently causing
trouble from `struct iwl_tx_cmd` to `struct iwl_tx_cmd_hdr`.
We also want to ensure that when new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement `struct iwl_tx_cmd_hdr`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
So, with these changes, fix the following warnings:
drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2315:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

Roll-back to use iwlmvm for those devices. iwlmld will support wifi7
capable devices only. The firmware for the non-wifi7 capable will soon
be frozen and we don't want iwlmld to have to support devices that will
require the old APIs.

We use CD/DVD drives under Marvell 88SE9215 SATA controller on many
Loongson-based machines. We found its PIO doesn't work well, and on the
opposite its DMA seems work very well.
We don't know the detail of the 88SE9215 SATA controller, but we have
tested different CD/DVD drives and they all have problems under 88SE9215
(but they all work well under an Intel SATA controller). So, we consider
this problem is bound to 88SE9215 SATA controller rather than bound to
CD/DVD drives.
As a solution, we define a new dedicated AHCI board id which is named
board_ahci_yes_fbs_atapi_dma for 88SE9215, and for this id we set the
AHCI_HFLAG_ATAPI_DMA_QUIRK and ATA_QUIRK_ATAPI_MOD16_DMA flags on the
SATA controller in order to prefer ATAPI DMA.

When invalidating an address range in mlx5, there is an optimization to
do UMR operations in chunks.
Previously, the invalidation counter was incorrectly updated for the
same indexes within a chunk. Now, the invalidation counter is updated
only when a chunk is complete and mlx5r_umr_update_xlt() is called.
This ensures that the counter accurately represents the number of pages
invalidated using UMR.

When cur_qp isn't NULL, in order to avoid fetching the QP from
the radix tree again we check if the next cqe QP is identical to
the one we already have.
The bug however is that we are checking if the QP is identical by
checking the QP number inside the CQE against the QP number inside the
mlx5_ib_qp, but that's wrong since the QP number from the CQE is from
FW so it should be matched against mlx5_core_qp which is our FW QP
number.
Otherwise we could use the wrong QP when handling a CQE which could
cause the kernel trace below.
This issue is mainly noticeable over QPs 0 & 1, since for now they are
the only QPs in our driver whereas the QP number inside mlx5_ib_qp
doesn't match the QP number inside mlx5_core_qp.

Change all variables storing mlx5_umem_mkc_find_best_pgsz() result to
unsigned long to support values larger than 31 and avoid overflow.
For example: If we try to register 4GB of memory that is contiguous in
physical memory, the driver will optimize the page_size and try to use
an mkey with 4GB entity size. The 'unsigned int' page_size variable will
overflow to '0' and we'll hit the WARN_ON() in alloc_cacheable_mr().

Fix double decrement of 'in_use' counter on push_mkey_locked() failure
while deregistering an MR.
If we fail to return an mkey to the cache in cache_ent_find_and_store()
it'll update the 'in_use' counter. Its caller, revoke_mr(), also updates
it, thus having double decrement.
Wrong value of 'in_use' counter will be exposed through debugfs and can
also cause wrong resizing of the cache when users try to set cache
entry size using the 'size' debugfs.
To address this issue, the 'in_use' counter is now decremented within
mlx5_revoke_mr() also after a successful call to
cache_ent_find_and_store() and not within cache_ent_find_and_store().
Other success or failure flows remains unchanged where it was also
decremented.

Add support to allow optional-counters binding to a QP, whereas when
a bind operation is requested depending on the counter optional-counter
binding state the driver will determine if to also add optional-counters
to this QP binding.
The optional-counter binding is done by simply adding a steering
rule for the specific optional-counter condition with the additional
match over that QP number.
Note that optional-counters per QP rules are handled on an earlier prio
than per device counters, and per device counter correctness is maintained
by core whereas it is responsible to sum active counters when checking device
counter and to add them to history count when they are deallocated.

Whenever a new counter is created, save inside it the user requested
configuration for optional-counters binding, for manual configuration it
is requested directly by the user and for the automatic configuration it
depends on if the automatic binding was enabled with or without
optional-counters binding.
This argument will later be used by the driver to determine if to bind the
optional-counters as well or not when trying to bind this counter to a QP.
It indicates that when binding counters to a QP we also want the
currently enabled link optional-counters to be bound as well.

Add the following optional counters:

Which counts all RDMA packets/bytes sent and received per link.
Note that since each direction packet and byte counter are shared,
the counter is only reset when both counters of that direction
are removed. But from user-perspective each can be enabled/disabled separately.
The counters can be enabled using:
sudo rdma stat set link rocep8s0f0/1 optional-counters rdma_tx_packets
And can be seen using:

This patch resolves an issue where RF calibration data from a
file could not be downloaded to the firmware. The feature to
download calibration data from a file was broken by the commit:
d39fbc88956e.
The issue arose because the function `mwifiex_cmd_cfg_data()`
was modified in a way that prevented proper handling of
file-based calibration data. While this patch restores the ability
to download RF calibration data from a file, it may inadvertently
break the feature to download calibration data from the device
tree. This is because the function `mwifiex_dnld_dt_cfgdata()`,
which also relies on `mwifiex_cmd_cfg_data()`, is still used for
device tree-based calibration data downloads.

iwl_mld_remove_link removes the link from both the FW and from the
driver.
If removing it from the FW failed, we assume that the FW is
dead anyway and remove it from the driver as well.
On the other hand, we still return an error value, indicating the caller
(i.e. mac80211) that the link couldn't be removed - while it was
actually removed.
Later, mac80211 might tell the driver again to remove that link,
and then the driver will warn that it doesn't exist.
Fix this by making iwl_mld_remove_link a void function.

E610 NICs unlike the previous devices utilising ixgbe driver
are notified in the case of overheating by the FW ACI event.
In event of overheat when threshold is exceeded, FW suspends all
traffic and sends overtemp event to the driver. Then driver
logs appropriate message and disables the adapter instance.
The card remains in that state until the platform is rebooted.
This approach is a solution to the fact current version of the
E610 FW doesn't support reading thermal sensor data by the
SW. So give to user at least any info that overtemp event
has occurred, without interface disappearing from the OS
without any note.
