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.

tcp_in_quickack_mode() is called from input path for small packets.
It calls __sk_dst_get() which reads sk->sk_dst_cache which has been
put in sock_read_tx group (for good reasons).
Then dst_metric(dst, RTAX_QUICKACK) also needs extra cache line misses.
Cache RTAX_QUICKACK in icsk->icsk_ack.dst_quick_ack to no longer pull
these cache lines for the cases a delayed ACK is scheduled.
After this patch TCP receive path does not longer access sock_read_tx
group.

For 'ti,j7200-cpb-audio' compatible, there is support for only one PLL for
48k. For 11025, 22050, 44100 and 88200 sampling rates, due to absence of
J721E_CLK_PARENT_44100, we get EINVAL while running any audio application.
Add support for these rates by using the 48k parent clock and adjusting

xfs_growfs_data needs to increment m_generation as soon as the primary

was part of xfs_growfs_data_private that mean the incremented had to be
done unconditionally once that was called. Later, commit 83a7f86e39ff

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.

====================
udp_tunnel: GRO optimizations
The UDP tunnel GRO stage is source of measurable overhead for workload
based on UDP-encapsulated traffic: each incoming packets requires a full
UDP socket lookup and an indirect call.
In the most common setups a single UDP tunnel device is used. In such
case we can optimize both the lookup and the indirect call.
Patch 1 tracks per netns the active UDP tunnels and replaces the socket
lookup with a single destination port comparison when possible.
Patch 2 tracks the different types of UDP tunnels and replaces the
indirect call with a static one when there is a single UDP tunnel type
active.
I measure ~5% performance improvement in TCP over UDP tunnel stream
tests on top of this series.

It's quite common to have a single UDP tunnel type active in the
whole system. In such a case we can replace the indirect call for
the UDP tunnel GRO callback with a static call.
Add the related accounting in the control path and switch to static
call when possible. To keep the code simple use a static array for
the registered tunnel types, and size such array based on the kernel
config.

Most UDP tunnels bind a socket to a local port, with ANY address, no
peer and no interface index specified.
Additionally it's quite common to have a single tunnel device per
namespace.
Track in each namespace the UDP tunnel socket respecting the above.
When only a single one is present, store a reference in the netns.
When such reference is not NULL, UDP tunnel GRO lookup just need to
match the incoming packet destination port vs the socket local port.
The tunnel socket never sets the reuse[port] flag[s]. When bound to no
address and interface, no other socket can exist in the same netns
matching the specified local port.
Matching packets with non-local destination addresses will be
aggregated, and eventually segmented as needed - no behavior changes
intended.
Note that the UDP tunnel socket reference is stored into struct
netns_ipv4 for both IPv4 and IPv6 tunnels. That is intentional to keep
all the fastpath-related netns fields in the same struct and allow
cacheline-based optimization. Currently both the IPv4 and IPv6 socket
pointer share the same cacheline as the `udp_table` field.

mlx5: Support setting a parent for a devlink rate node
This series by Carolina adds mlx5 support for the setting of a parent to
devlink rate nodes.
By introducing a hierarchical level to scheduling nodes, these changes
allow for more granular control over bandwidth allocation and isolation
of Virtual Functions.
Function renaming for parent setting on leafs:
- net/mlx5: Rename devlink rate parent set function for leaf nodes
Add support for hierarchy level tracking:
- net/mlx5: Introduce hierarchy level tracking on scheduling nodes
- net/mlx5: Preserve rate settings when creating a rate node
Support setting parent for rate nodes:
- net/mlx5: Add support for setting parent of nodes

Introduce `mlx5_esw_devlink_rate_node_parent_set()` to allow assigning
a parent to scheduling nodes.
Implement `mlx5_esw_qos_node_update_parent()` and
`mlx5_esw_qos_node_validate_set_parent()` to enforce constraints on
node reassignment.
Don't allow reassignment of nodes with active rate objects.
Update `esw_qos_node_set_parent()` to handle cases where
the parent is NULL. A NULL parent indicates that the scheduling element
is attached to the root scheduling element, and since only rate nodes
can be connected to the root, this update is now necessary.

Modify `esw_qos_create_node_sched_elem()` to receive max_rate and
bw_share values while maintaining the previous configuration.
This change is essential for the upcoming patch that will modify rate
nodes and requires the existing settings to be preserved unless
explicitly changed.

Add a `level` field to `mlx5_esw_sched_node` to track the hierarchy
depth of each scheduling node. This allows enforcement of the
scheduling depth constraints based on `log_esw_max_sched_depth`.
Modify `esw_qos_node_set_parent()` and `__esw_qos_alloc_node()` to
correctly assign hierarchy levels. Ensure that nodes inherit their
parent’s level incrementally.

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.

This patch resolves an issue where RF calibration data was being
released before the download process. Without this fix, the

syzbort reported a uninitialize wiphy_work_lock in cfg80211_dev_free. [1]
After rfkill allocation fails, the wiphy release process will be performed,
which will cause cfg80211_dev_free to access the uninitialized wiphy_work
related data.
Move the initialization of wiphy_work to before rfkill initialization to
avoid this issue.

INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?

When userspace sets supported rates for a new station via
NL80211_CMD_NEW_STATION, it might send a list that's empty
or contains only invalid values. Currently, we process these
values in sta_link_apply_parameters() without checking the result of
ieee80211_parse_bitrates(), which can lead to an empty rates bitmap.
A similar issue was addressed for NL80211_CMD_SET_BSS in commit
ce04abc3fcc6 ("wifi: mac80211: check basic rates validity").
This patch applies the same approach in sta_link_apply_parameters()
for NL80211_CMD_NEW_STATION, ensuring there is at least one valid
rate by inspecting the result of ieee80211_parse_bitrates().
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

This patch addresses an issue where, despite the AP supporting 40MHz
bandwidth, the connection was limited to 20MHz. Without this fix,
even if the access point supports 40MHz, the bandwidth after
connection remains at 20MHz. This issue is not a regression.
