Currently, the driver uses phylib to operate PHY by default.
On some boards, the PHY device is separated from the MAC device.
As a result, the hibmcge driver cannot operate the PHY device.
In this patch, the driver determines whether a PHY is available
based on register configuration. If no PHY is available,
the driver will use fixed_phy to register fake phydev.

Use the newly added of_reserved_mem_region_to_resource{_byname}()
functions to handle "memory-region" properties.
The error handling is a bit different for mtk_wed_mcu_load_firmware().
A failed match of the "memory-region-names" would skip the entry, but
then other errors in the lookup and retrieval of the address would not
skip the entry. However, that distinction is not really important.
Either the region is available and usable or it is not. So now, errors
from of_reserved_mem_region_to_resource() are ignored so the region is
simply skipped.

In LACP mode with broadcast_neighbor enabled, after LACP protocol
recovery, the port can transmit packets. However, if the bond port
doesn't send gratuitous ARP/ND packets to the switch, the switch
won't return packets through the current interface. This causes
traffic imbalance. To resolve this issue, when LACP protocol recovers,
send ARP/ND packets if broadcast_neighbor is enabled.

Stacking technology is a type of technology used to expand ports on
Ethernet switches. It is widely used as a common access method in
large-scale Internet data center architectures. Years of practice
have proved that stacking technology has advantages and disadvantages
in high-reliability network architecture scenarios. For instance,
in stacking networking arch, conventional switch system upgrades
require multiple stacked devices to restart at the same time.
Therefore, it is inevitable that the business will be interrupted
for a while. It is for this reason that "no-stacking" in data centers
has become a trend. Additionally, when the stacking link connecting
the switches fails or is abnormal, the stack will split. Although it is
not common, it still happens in actual operation. The problem is that
after the split, it is equivalent to two switches with the same
configuration appearing in the network, causing network configuration
conflicts and ultimately interrupting the services carried by the
stacking system.
To improve network stability, "non-stacking" solutions have been
increasingly adopted, particularly by public cloud providers and
tech companies like Alibaba, Tencent, and Didi. "non-stacking" is
a method of mimicing switch stacking that convinces a LACP peer,
bonding in this case, connected to a set of "non-stacked" switches
that all of its ports are connected to a single switch
(i.e., LACP aggregator), as if those switches were stacked. This
enables the LACP peer's ports to aggregate together, and requires
(a) special switch configuration, described in the linked article,
and (b) modifications to the bonding 802.3ad (LACP) mode to send
all ARP/ND packets across all ports of the active aggregator.
Note that, with multiple aggregators, the current broadcast mode
logic will send only packets to the selected aggregator(s).

Matcher size is dynamic: it starts at initial size, and then it grows
through rehash as more and more rules are added to this matcher.
When rules are deleted, matcher's size is not decreased. Rehash
approach is greedy. The idea is: if the matcher got to a certain size
at some point, chances are - it will get to this size again, so it is
better to avoid costly rehash operations whenever possible.
However, when all the rules of the matcher are deleted, this should
be viewed as special case. If the matcher actually got to the point
where it has zero rules, it might be an indication that some usecase
from the past is no longer happening. This is where some ICM can be
freed.
This patch handles this case: when a number of rules in a matcher
goes down to zero, the matcher's tables are shrunk to the initial
size.

Track and grow matcher sizes individually for RX and TX RTCs. This
allows RX-only or TX-only use cases to effectively halve the device
resources they use.

measured the number of pages the device requests, and memory usage as
reported by `free -h`.

Matchers were using the pool abstraction solely as a convenience
to allocate two STE ranges. The pool's core functionality, that
of allocating individual items from the range, was unused.
Matchers rely either on the hardware to hash rules into a table,
or on a user-provided index.
Remove the STE pool from the matcher and allocate the STE ranges
manually instead.

Use a dedicated "mmio-sram" node and the generic allocator
instead of open-coding SRAM allocation for DMA rings.
Keep support for legacy device trees but notify the user via a
warning to update, and let the ethernet driver create the
gen_pool in this case.

The previous commit unintentionally removed the code responsible for
enabling WoL via MMD3 register 0x8012 BIT5. As a result, Wake-on-LAN
(WoL) support for the QCA808X PHY is no longer functional.
The WoL (Wake-on-LAN) feature for the QCA808X PHY is enabled via MMD3
register 0x8012, BIT5. This implementation is aligned with the approach
used in at8031_set_wol().

Currently, ath12k driver maintains a counter to store the number of
stations connected to each radio. However, at certain times like
debugging, it is useful to know number of stations connected to any
one of the interface in that radio.
Add support to maintain a counter for number of stations connected to
each interface.

Currently, the HTT_H2T_MSG_TYPE_PPDU_STATS_CFG request uses bits
8 to 15 as the bitmask for HTT_PPDU_STATS_CFG_PDEV_ID for firmware
PPDU_STATS. However, bit 8 is reserved for SOC stats, and the actual
PDEV ID should be encoded using bits 9 to 15. This leads to incorrect
PDEV ID encoding in the request, causing it to either ignore the
request or apply it to the wrong PDEV.
Additionally, pdev_mask calculation is done as
pdev_mask = 1 << (i + 1); (i.e. i= num_rxmda_per_pdev)
but this is not valid for multiple pdevs(multi-MAC configurations)
with 1 rxdma per pdev, as this will mask the same value for all pdevs.
To correctly identify each and exact MAC in multi-MAC configurations,
the calculation should include ar->pdev_idx:
pdev_mask = 1 << i + ar->pdev_idx;
Due to these issues, the firmware does not send PPDU_STATS for the
intended PDEV, leading to inaccurate and incomplete statistics on the
host. This might trigger certain WARN_ON() conditions in host that
rely on these statistics.
Hence, change the bitmask for HTT_PPDU_STATS_CFG_PDEV_ID as bit 9
to 15 to properly fill the pdev id in request message and change
the pdev_mask calculation to consider ar->pdev_idx to mask pdev
correctly.

Ensure that all radios remain down when the driver operates in Factory
Test Mode (FTM). Reject any userspace attempts to bring up an
interface in this mode.
Currently, the driver allows userspace to bring up the interface even
though it operates in FTM mode, which violates FTM constraints and
leads to FTM command failures.
Hence, block the radio start when the driver is in FTM mode. Also,
remove ath12k_ftm_mode check from ath12k_drain_tx() because FTM mode
check is already handled in the caller function
(ath12k_mac_op_start()).

htt_ppdu_stats_user_cmpltn_common_tlv
Currently, tx_retries and tx_failed are updated only in mac80211 during
tx_completion path for sta->deflink. This works fine for non-ML
station but for multi-link (ML) station, these values should be updated
for sta->link[link_id] as per tx link_id. However, in tx_completion path
there is no way to determine the link_id for which packet is retried or
failed.
Therefore, update the tx_retries and tx_failed in arsta structure from
htt_ppdu_stats_user_cmpltn_common_tlv during
ath12k_update_per_peer_tx_stats() call to utilize the values from arsta.
Also, during 'iw dev xxxx station dump' populate the tx_retries and
tx_failed in station_info structure to ensure values are correctly
reflected.
