Currently, during mac80211 allocate and register single device is
considered for the registration. But, in future, during multi device
group abstraction is introduced, all the devices has to be combined
together as a single abstraction and then hardware should be allocated.
All the devices in the group should be combined together only if it
supports inter device mlo capability. The decision of whether to combine
the devices or not can be based on the mlo capability flag in
ath12k_hw_group.
By default, mlo_capable flag in the group would be set as false. During
QMI PHY capability exchange, only when we have more than one chip in the
group or if one chip, then that chip supports inter MLO, then mlo_capable
flag in the group will be enabled.
Add changes to introduce mlo_capable flag for device group and refactor
ath12k_mac_hw_allocate() api based on device group (ag) rather than
device (ab).

QMI host capability has the information regarding MLO parameters such as
device_id, MLO capability, group id and the information of each devices
involved in the group and sent immediately on QMI server arrive event.
Currently, only one device is involved in the group and hence, single
device information is sent as part of MLO capability of host.
But, in future when multi device group abstraction is introduced, host
should send all the device information involved in the group as part
of QMI MLO host capability rather than single device. Hence, sending
QMI host capability immediately on server arrive of a device might not
be ideal for multi device group abstraction as the details of other
devices in the group would not be available.
Hence, once QMI server arrive event is received, request for QMI PHY
capabilities of device, and defer the host capability send for that device.
After QMI PHY capability is received for all the devices in the group
trigger the host capability event for the deferred devices in the group.
Hence, add changes to defer the QMI host capability event until the device
group is ready and then resume the QMI exchange for all the device with
host capabilities.

Currently, hardware abstractions (ah) of different radio bands are tightly
coupled to a single device (ab). But, with hardware device group abstraction
(ag), multiple radios across different devices in a group can form different
combinations of hardware abstractions (ah) within the group. Hence, the mapping
between ah to ab can be removed and instead it can be mapped with struct
ath12k_hw_group (ag).
Current mapping between struct ath12k_hw (ah), struct ath12k_base (ab) and struct
ath12k_hw_group (ag):
+------------------------------------------------+
| +-------------------------------------+ |
| | +---------------+ +---------------+ | |
| | |ath12k_hw (ah) | |ath12k_hw (ah) | | |
| | +---------------+ +---------------+ | |
| | | |
| | +-----------+ | +-----------+ | |
| | | ar (2GHz) | | | ar (5GHz) | | |
| | +-----------+ | +-----------+ | |
| | Dual band device-1 (ab) | |
| +-------------------------------------+ |
| ath12k_hw_group (ag) based on group id |
+------------------------------------------------+
After hardware device group abstraction moving ah array out of ab to ag:
+----------------------------------------------+
| +---------------+ +---------------+ |
| |ath12k_hw (ah) | |ath12k_hw (ah) | |
| +---------------+ +---------------+ |
| +-------------------------------------+ |
| | +-----------+ +-----------+ | |
| | | ar (2GHz) | | ar (5GHz) | | |
| | +-----------+ +-----------+ | |
| | Dual band device-1 (ab) | |
| +-------------------------------------+ |
| ath12k_hw_group (ag) based on group id |
+----------------------------------------------+
This decoupling of struct ath12k_hw (ah) from struct ath12k_base (ab) and
mapping it to struct ath12k_hw_group (ag) will help in forming different
combinations of multi-link devices.

Currently, mac allocate/register and core_pdev_create are initiated immediately
when QMI firmware ready event is received for a particular device. With
hardware device group abstraction, QMI firmware ready event can be received
simultaneously for different devices in the group and so, it should not be
registered immediately rather it has to be deferred until all devices in the
group has received QMI firmware ready.
To handle this, refactor the code of core start to have registering within
ath12k_core_hw_group_start() and unregistering in ath12k_core_hw_group_stop().

Currently, single device is probed, and once firmware is ready, the device
is registered to mac80211. For Multi-Link Operation, different bands of
different devices or same device are part of a single wiphy and for
this, hardware device group abstraction is needed.
Hardware device group abstraction - when there are multiple devices (with
single radio or dual radio) that are connected by any means of interface
for communicating between them, then these devices can be combined
together as a single group using a group id to form a group abstraction
and register to mac80211.
The grouping information of multiple devices would be based on device tree
during device probe (will be implemented in future patches). If no such
information is available, then a single device will be part of group abstraction
and registered to mac80211, else multiple devices advertised in device tree are
combined and then registered to mac80211.
For device group abstraction, a base structure ath12k_hw_group (ag) and the
helpers are implemented. These helpers are used during device probe and mapping
the group to the devices involved.
An illustration of how multiple devices might be combined together in
future based on group id:
+------------------------------------------------------------------------+
| +-------------------------------------+ +-------------------+ |
| | +-----------+ | | +-----------+ | | +-----------+ | |
| | | ar (2GHz) | | | | ar (5GHz) | | | | ar (6GHz) | | |
| | +-----------+ | | +-----------+ | | +-----------+ | |
| | ath12k_base (ab) | | ath12k_base (ab) | |
| | (Dual band device) | | | |
| +-------------------------------------+ +-------------------+ |
| ath12k_hw_group (ag) based on group id |
+------------------------------------------------------------------------+
In the above representation, two devices are combined into single group
based on group id.
Add base code changes where single device would be part of a group with an
invalid group id forming an group abstraction. Multi device grouping will
be introduced in future.

At present, the mlo_capable_flags in ath12k_base is used to indicate whether
the chip supports inter (QCN9274) or intra (WCN7850) chip MLO. However, it’s
possible that the chip supports neither, especially with older firmware
versions. Additionally, if intra chip MLO is not supported, inter chip MLO will
also be non-functional. Therefore, having two separate flags for this is
unnecessary.
Therefore, rename this flag to single_chip_mlo_supp. At the same time convert
it into a bool data type. Also, get rid of the enums defined earlier.
For the QCN9274 family of chipsets, this will be set only when firmware
advertises the support during the QMI exchange.
For the WCN7850 family of chipsets, since the event is not supported,
assumption is made that single chip MLO is supported.

When hardware device group abstraction is introduced, a group abstraction is
registered to mac80211 rather than a particular single device. So we cannot
set the device registered when the QMI firmware ready event is received, only
after all the devices in group have received the event. To do that set and
unset ATH12K_FLAG_REGISTERED flag inside ath12k_mac_register() and
ath12k_mac_unregister() respectively.

Previously a workaround was added to avoid syndrome 0xcdb051. It is
triggered when offload a rule with tunnel encapsulation, and
forwarding to another table, but not matching on the internal port in
firmware steering mode. The original workaround skips internal tunnel
port logic, which is not correct as not all cases are considered. As
an example, if vlan is configured on the uplink port, traffic can't
pass because vlan header is not added with this workaround. Besides,
there is no such issue for software steering. So, this patch removes
that, and returns error directly if trying to offload such rule for
firmware steering.

In a multi-PF netdev, each traffic channel creates its own resources
against a specific PF.
In the cited commit, where this support was added, the channel_param
logic was mistakenly kept unchanged, so it always used the primary PF
which is found at priv->mdev.
In this patch we fix this by moving the logic to be per-channel, and
passing the correct mdev instance.
This bug happened to be usually harmless, as the resulting cparam
structures would be the same for all channels, due to identical FW logic
and decisions.
However, in some use cases, like fwreset, this gets broken.
This could lead to different symptoms. Example:
Error cqe on cqn 0x428, ci 0x0, qn 0x10a9, opcode 0xe, syndrome 0x4,
vendor syndrome 0x32

Commit 7ed816be35ab ("eth: bnxt: use page pool for head frags") added a
page pool for header frags, which may be distinct from the existing pool
for the aggregation ring. Prior to this change, frags used in the TPA
ring rx_tpa were allocated from system memory e.g. napi_alloc_frag()
meaning their lifetimes were not associated with a page pool. They can
be returned at any time and so the queue API did not alloc or free
rx_tpa.
But now frags come from a separate head_pool which may be different to
page_pool. Without allocating and freeing rx_tpa, frags allocated from
the old head_pool may be returned to a different new head_pool which
causes a mismatch between the pp hold/release count.
Fix this problem by properly freeing and allocating rx_tpa in the queue
API implementation.

on a single tpa_info in prep for queue API using them.
There are 2 pairs of operations:
* bnxt_alloc_one_tpa_info()
* bnxt_free_one_tpa_info()
These alloc/free the tpa_info array itself.
* bnxt_alloc_one_tpa_info_data()
* bnxt_free_one_tpa_info_data()

Support for in-band signalling with Serdes links is uncertain. Some
PHYs do not support in-band for e.g. SGMII. Some PCS do not support
in-band for 2500Base-X. Some PCS require in-band for Base-X protocols.
Simply using what is in DT is insufficient when we have hot-pluggable
PHYs e.g. in the form of SFP modules, which may not provide the
in-band signalling.
In order to address this, we have introduced phy_inband_caps() and
pcs_inband_caps() functions to allow phylink to retrieve the
capabilities from each end of the PCS/PHY link. This commit adds code
to resolve whether in-band will be used in the various scenarios that
we have: In-band not being used, PHY present using SGMII or Base-X,
PHY not present. We also deal with no capabilties provided.

optical SFPs can be supported.
When a PCS does not provide a method, we allow inband negotiation to
be either on or off, making this a no-op until the pcs_inband_caps()
method is implemented by a PCS driver.

Add a method to query the PHY's in-band capabilities for a PHY
interface mode.
Where the interface mode does not have in-band capability, or the PHY
driver has not been updated to return this information, then
phy_inband_caps() should return zero. Otherwise, PHY drivers will
return a value consisting of the following flags:
LINK_INBAND_DISABLE indicates that the hardware does not support
in-band signalling, or can have in-band signalling configured via
software to be disabled.
LINK_INBAND_ENABLE indicates that the hardware will use in-band
signalling, or can have in-band signalling configured via software
to be enabled.
LINK_INBAND_BYPASS indicates that the hardware has the ability to
bypass in-band signalling when enabled after a timeout if the link
partner does not respond to its in-band signalling.
This reports the PHY capabilities for the particular interface mode,
not the current configuration.

There is an interdependence between the current link_an_mode and
pcs_neg_mode that some drivers rely upon to know whether inband or PHY
mode will be used.
In order to support detection of PCS and PHY inband capabilities
resulting in automatic selection of inband or PHY mode, we need to
cater for this, and support changing the MAC link_an_mode. However, we
end up with an inter-dependency between the current link_an_mode and
pcs_neg_mode.
To solve this, split the current link_an_mode into the requested
link_an_mode and active link_an_mode. The requested link_an_mode will
always be passed to phylink_pcs_neg_mode(), and the active link_an_mode
will be used for everything else, and only updated during
phylink_major_config(). This will ensure that phylink_pcs_neg_mode()'s
link_an_mode will not depend on the active link_an_mode that will,
in a future patch, depend on pcs_neg_mode.

The driver is currently using an ACL key block that is not supported by
Spectrum-4. This works because the driver is only using a single field
from this key block which is located in the same offset in the
equivalent Spectrum-4 key block.
The issue was discovered when the firmware started rejecting the use of
the unsupported key block. The change has been reverted to avoid
breaking users that only update their firmware.
Nonetheless, fix the issue by using the correct key block.

The exposed statistics allows easier debugging of cases when netconsole

Stats are not reset on enable/disable/change remote ip/etc, they

Currently, TX power is reported on interface/wdev level as

Add support to send tx power for all valid links of an MLD as

As far as userspace is concerned, there is no behavioral change
for Non-ML Interfaces. For ML interfaces, userspace should fetch
TX power that is nested inside NL80211_ATTR_MLO_LINKS, similar to
how channel info(NL80211_ATTR_WIPHY_FREQ) is fetched.
