EHT capable devices will only use iwlmld. So we can remove EMLSR code
from iwlmvm.
As part of removal, remove IWL_MVM_ESR_EXIT_FAIL_ENTRY EMLSR state.

A multi-link client can use any link for transmissions. It can decide to
put one link in power save mode for longer periods while listening on the
other links as per MLD listen interval. Unicast management frames sent to
that link station might get dropped if that link station is in power save
mode or inactive. In such cases, firmware can take decision on which link
to use.
Allow the firmware to decide on which link management frame should be
sent on, by filling the hardware link with maximum value of u32, so that
the firmware will not have a specific link to transmit data on and so
the management frames will be link agnostic. For QCN devices, all action
frames are marked as link agnostic. For WCN devices, if the device is
configured as an AP, then all frames other than probe response frames,
authentication frames, association response frames, re-association response
frames and ADDBA response frames are marked as link agnostic and if the
device is configured as a station, then all frames other than probe request
frames, authentication frames, de-authentication frames and ADDBA response
frames are marked as link agnostic.

The QCN9274 supports two memory profiles: a default profile and a
low-memory profile. The driver signals the firmware to enable
low-memory optimizations using the QMI initialization service.
Add support to select the low-memory profile on system with less than
512 MB RAM.

Currently, host sends num_tids (number of TID (Traffic Identifier))
value to firmware via WMI_INIT_CMD during WMI initialization. However,
the firmware does not use this value, as it determines the number of
TIDs using its own internal logic.
Hence, remove the redundant num_tids calculation logic for QCN9274.

Introduce ath12k_mem_profile_based_param structure to define
configuration parameters for both default and low-memory profiles.
Add support for enabling the low-memory profile in the follow-up
patch by making the following changes:
- Reduce sizes for transmit, receive, and monitor descriptor rings.
- Reduce transmit and receive descriptor count.
- Limit the maximum number of virtual devices (vdevs) to 9.
- Reduce the maximum number of client support per radio.
Centralize these parameters in the ath12k_mem_profile_based_param
structure to simplify switching between memory profiles.

'struct regmap_config' are not modified in these drivers. They be
statically defined instead of allocated and populated at run-time.
The main benefits are:
- it saves some memory at runtime
- the structures can be declared as 'const', which is always better for
structures that hold some function pointers
- the code is less verbose

Tony Nguyen says:
====================
ice: cleanups and preparation for live migration
Jake Keller says:
Various cleanups and preparation to the ice driver code for supporting
SR-IOV live migration.
The logic for unpacking Rx queue context data is added. This is the inverse
of the existing packing logic. Thanks to <linux/packing.h> this is trivial
to add.
Code to enable both reading and writing the Tx queue context for a queue
over a shared hardware register interface is added. Thanks to ice_adapter,
this is locked across all PFs that need to use it, preventing concurrency
issues with multiple PFs.
The RSS hash configuration requested by a VF is cached within the VF
structure. This will be used to track and restore the same configuration
during migration load.
ice_sriov_set_msix_vec_count() is updated to use pci_iov_vf_id() instead of
open-coding a worse equivalent, and checks to avoid rebuilding MSI-X if the
current request is for the existing amount of vectors.
A new ice_get_vf_by_dev() helper function is added to simplify accessing a
VF from its PCI device structure. This will be used more heavily within the
live migration code itself.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: introduce ice_get_vf_by_dev() wrapper
ice: avoid rebuilding if MSI-X vector count is unchanged
ice: use pci_iov_vf_id() to get VF ID
ice: expose VF functions used by live migration
ice: move ice_vsi_update_l2tsel to ice_lib.c
ice: save RSS hash configuration for migration
ice: add functions to get and set Tx queue context
ice: add support for reading and unpacking Rx queue context

The code had some rather odd control flow inherited from when it was
shared with siena and ef10 before this driver was split out.
Simplify that for easier reading.
Also add a comment explaining why we return the values we do, since
some Falcon documents and datasheets confusingly mention the part
supporting 4-tuple UDP hashing.
(I couldn't find any record of exactly what was "broken" about the
original Falcon A hash, I'm just trusting that falcon_init_rx_cfg()
had a good reason for not using it.)

In the current code, if there was a rekey, we remove all the existing keys
from mac80211, then re-add the ones that the FW sent with
ieee80211_gtk_rekey_add, (newer FW will send also the existing GTKs/BIGTKs)
and then update the sequence number.
Instead of removing and re-adding the existing keys for no good reason,
we can just update the sequence of all keys, also of the ones that are
going to be replaced, and update again after the replace.
This change is required because ieee80211_gtk_rekey_add is going to be
changed to lookup the cipher from the old key instead of receiving it as an
argument, and for this it will need the old key(s), so we can't remove all
keys.
Note that with this change, in case that a key that existed before wowlan
is replaced, mac80211 will now call the driver to remove the old key and
add the new one (as opposed the previous behaviour, in which the key was
removed by the driver itself).
Of course we don't want to run the set_key callbacks in this case, so just
return early.

The default capabilities were set to much more than the hardware
currently is intended to support, and then masked off for only
the GL MAC type. However, this was due to some miscommunication
and is incorrect, it should've been masked off for all current
and planned MACs/RFs. Instead of doing this removing and adding
of capabilities, simply list the ones that currently apply to
all devices. If this changes for a new device type we can change
the code, but at least the driver won't erroneously advertise
some capabilities that aren't actually implemented in hardware.

When a GO is started, the P2P device mac is updated to indicate
that frames for the P2P device mac should be filtered in while
the GO is active. However, this configuration is done after the GO is
already started so it doesn't take effect. Fix it by updating the
P2P device mac before adding the broadcast station, which actually
starts the GO.

Currently, packets are being received into the WBM error ring when
REO queue lookup is enabled, resulting in degraded RX performance.
The issue arises because the REO queue LUT TID memory reference is
set to zero-it's being assigned before the memory is allocated.
Fix this by assigning the REO queue TID memory reference in the LUT
immediately after memory allocation to ensure correct packet
processing.

An optimization for promiscuous mode adds a high-priority steering
table with a single catch-all rule to steer all traffic directly to
the TTC table.
However, a gap exists between the creation of this table and the
insertion of the catch-all rule. Packets arriving in this brief window
would miss as no rule was inserted yet, unnecessarily incrementing the
'rx_steer_missed_packets' counter and dropped.
This patch resolves the issue by introducing a new prio for this
table, placing it between MLX5E_TC_PRIO and MLX5E_NIC_PRIO. By doing
so, packets arriving during the window now fall through to the next
prio (at MLX5E_NIC_PRIO) instead of being dropped.

There's a race between disabling DIM and NAPI callbacks using the dim
pointer on the RQ or SQ.
If NAPI checks the DIM state bit and sees it still set, it assumes
`rq->dim` or `sq->dim` is valid. But if DIM gets disabled right after
that check, the pointer might already be set to NULL, leading to a NULL
pointer dereference in net_dim().
Fix this by calling `synchronize_net()` before freeing the DIM context.
This ensures all in-progress NAPI callbacks are finished before the
pointer is cleared.

Restrict the 100Mbit forced-mode workaround to link-down transitions
only, to prevent repeated link reset cycles in certain configurations.
The workaround was originally introduced to improve signal reliability
when switching cables between long and short distances. It temporarily
forces the PHY into 10 Mbps before returning to 100 Mbps.
However, when used with autonegotiating link partners (e.g., Intel i350),
executing this workaround on every link change can confuse the partner
and cause constant renegotiation loops. This results in repeated link
down/up transitions and the PHY never reaching a stable state.
Limit the workaround to only run during the PHY_NOLINK state. This ensures
it is triggered only once per link drop, avoiding disruptive toggling
while still preserving its intended effect.
Note: I am not able to reproduce the original issue that this workaround
addresses. I can only confirm that 100 Mbit mode works correctly in my
test setup. Based on code inspection, I assume the workaround aims to
reset some internal state machine or signal block by toggling speeds.
However, a PHY reset is already performed earlier in the function via
phy_init_hw(), which may achieve a similar effect. Without a reproducer,
I conservatively keep the workaround but restrict its conditions.

Enable .soft_reset for the LAN88xx PHY driver by assigning
genphy_soft_reset() to ensure that the phylib core performs a proper
soft reset during reconfiguration.
Previously, the driver left .soft_reset unimplemented, so calls to
phy_init_hw() (e.g., from lan88xx_link_change_notify()) did not fully
reset the PHY. As a result, stale contents in the Link Partner Ability
(LPA) register could persist, causing the PHY to incorrectly report
that the link partner advertised autonegotiation even when it did not.
Using genphy_soft_reset() guarantees a clean reset of the PHY and
corrects the false autoneg reporting in these scenarios.
