Registering the interrupts for TX or RX DMA Channels prior to registering
their respective NAPI callbacks can result in a NULL pointer dereference.
This is seen in practice as a random occurrence since it depends on the
randomness associated with the generation of traffic by Linux and the
reception of traffic from the wire.

====================
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.

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.

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.

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.

Newer FW can set the CAPS_CHANGE flag during ifup if some capabilities
or configurations have changed. For example, the CoS queue
configurations may have changed. Support this new flag by treating it
almost like FW reset. The driver will essentially rediscover all
features and capabilities, reconfigure all backing store context memory,
reset everything to default, and reserve all resources.

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.

E830 supports raw receive and generic transmit checksum offloads.
Raw receive checksum support is provided by hardware calculating the
checksum over the whole packet, regardless of type. The calculated
checksum is provided to driver in the Rx flex descriptor. Then the driver
assigns the checksum to skb->csum and sets skb->ip_summed to
CHECKSUM_COMPLETE.
Generic transmit checksum support is provided by hardware calculating the
checksum given two offsets: the start offset to begin checksum calculation,
and the offset to insert the calculated checksum in the packet. Support is
advertised to the stack using NETIF_F_HW_CSUM feature.
E830 has the following limitations when both generic transmit checksum
offload and TCP Segmentation Offload (TSO) are enabled:
1. Inner packet header modification is not supported. This restriction
includes the inability to alter TCP flags, such as the push flag. As a
result, this limitation can impact the receiver's ability to coalesce
packets, potentially degrading network throughput.
2. The Maximum Segment Size (MSS) is limited to 1023 bytes, which prevents
support of Maximum Transmission Unit (MTU) greater than 1063 bytes.
Therefore NETIF_F_HW_CSUM and NETIF_F_ALL_TSO features are mutually
exclusive. NETIF_F_HW_CSUM hardware feature support is indicated but is not
enabled by default. Instead, IP checksums and NETIF_F_ALL_TSO are the
defaults. Enforcement of mutual exclusivity of NETIF_F_HW_CSUM and
NETIF_F_ALL_TSO is done in ice_set_features(). Mutual exclusivity
of IP checksums and NETIF_F_HW_CSUM is handled by netdev_fix_features().
When NETIF_F_HW_CSUM is requested the provided skb->csum_start and
skb->csum_offset are passed to hardware in the Tx context descriptor
generic checksum (GCS) parameters. Hardware calculates the 1's complement
from skb->csum_start to the end of the packet, and inserts the result in
the packet at skb->csum_offset.

Before commit 7627a0edef54 ("ata: ahci: Drop low power policy board type")
the ATI AHCI controllers specified board type 'board_ahci' rather than
board type 'board_ahci'. This means that LPM was historically not enabled
for the ATI AHCI controllers.
By looking at commit 7a8526a5cd51 ("libata: Add ATA_HORKAGE_NO_NCQ_ON_ATI
for Samsung 860 and 870 SSD."), it is clear that, for some unknown reason,
that Samsung SSDs do not play nice with ATI AHCI controllers. (When using
other AHCI controllers, NCQ can be enabled on these Samsung SSDs without
issues.)
In a similar way, from user reports, it is clear the ATI AHCI controllers
can enable LPM on e.g. Maxtor HDDs perfectly fine, but when enabling LPM
on certain Samsung SSDs, things break. (E.g. the SSDs will not get detected
by the ATI AHCI controller even after a COMRESET.)
Yet, when using LPM on these Samsung SSDs with other AHCI controllers, e.g.
Intel AHCI controllers, these Samsung drives appear to work perfectly fine.
Considering that the combination of ATI + Samsung, for some unknown reason,
does not seem to work well, disable LPM when detecting an ATI AHCI
controller with a problematic Samsung SSD.
Apply this new ATA_QUIRK_NO_LPM_ON_ATI quirk for all Samsung SSDs that have
already been reported to not play nice with ATI (ATA_QUIRK_NO_NCQ_ON_ATI).

The WIPHY_DEBUGFS_READ_WRITE_FILE_OPS_MLD macro is intended to call
read/write handlers with the wiphy lock held. However, the current
implementation uses the MLD_DEBUGFS_READ_WRAPPER macro, which does
not hold the wiphy lock during read operations. This fix updates
the WIPHY_DEBUGFS_READ_WRITE_FILE_OPS_MLD macro to use the
WIPHY_DEBUGFS_READ_WRAPPER_MLD macro instead, ensuring that the

====================
net: phy: Rework linkmodes handling in a dedicated file
This is V5 of the phy_caps series. In a nutshell, this series reworks the way
we maintain the list of speed/duplex capablities for each linkmode so that we
no longer have multiple definition of these associations.
That will help making sure that when people add new linkmodes in
include/uapi/linux/ethtool.h, they don't have to update phylib and phylink as
well, making the process more straightforward and less error-prone.
It also generalises the phy_caps interface to be able to lookup linkmodes
from phy_interface_t, which is needed for the multi-port work I've been working
on for a while.
This V5 addresse Russell's and Paolo's reviews, namely :
- Error out when encountering an unknown SPEED_XXX setting
It prints an error and fails to initialize phylib. I've tested by
introducing a dummy 1.6T speed, I guess it's only a matter of time
before that actually happens :)
- Deal more gracefully with the fixed-link settings, keeping some level of
compatibility with what we had before by making sure we report a
single BaseT mode like before.

Phylink has internal code to get the MAC capabilities of a given PHY
interface (what are the supported speed and duplex).
Extract that into phy_caps, but use the link_capa for conversion. Add an
internal phylink helper for the link caps -> mac caps conversion, and
use this in phylink_caps_to_linkmodes().

phylink_caps_to_linkmodes() is used to derive a list of linkmodes that
can be conceivably exposed using a given set of speeds and duplex
through phylink's MAC capabilities.
This list can be derived from the link_caps array in phy_caps, provided
we convert the MAC capabilities into a LINK_CAPA bitmask first.
Introduce an internal phylink helper phylink_caps_to_link_caps() to
convert from MAC capabilities into phy_caps, then phy_caps_linkmodes()
to do the link_caps -> linkmodes conversion.
This avoids having to update phylink for every new linkmode.

phylink allows MAC drivers to report the capabilities in terms of speed,
duplex and pause support. This is done through a dedicated set of enum
values in the form of the MAC_ capabilities. They are very close to what
the LINK_CAPA_xxx can express, with the difference that LINK_CAPA don't
have any information about Pause/Asym Pause support.
To prepare converting phylink to using the phy_caps, add the mapping
between MAC capabilities and phy_caps. While doing so, we move the
phylink_caps_params array up a bit to simplify future commits.
