In order to support live migration, the ice driver will need to read
certain data from the Rx queue context. This is stored in the hardware in a
packed format.
Since we use <linux/packing.h> for the mapping between the packed hardware
format and the unpacked structure, it is trivial to enable unpacking
support via the unpack_fields() function.
Add the ice_unpack_rxq_ctx() function based on the unpack_fields() API.
Re-use the same field definitions from the packing implementation.
Add ice_copy_rxq_ctx_from_hw() to copy the Rx queue context data from the
hardware registers.
Use these to implement ice_read_rxq_ctx() which will return the Rx queue
context to the caller in its unpacked ice_rlan_ctx struct.
This will enable the migration logic access to the relevant data about the
Rx device queues. It can easily be copied to the target system as part of
the migration payload, where it will be used to configure the Rx queues.

JF device is frozen on API 77. This prevented us from bumping the
minimum FW API of SO (and get rid of older FWs). This is because SO can
be combined with JF and then FW API 77 should be used.
Now as we have separate FW API ranges for the mac and the crf, we can
define for JF its own FW API range. This will allow bumping the minimum
FW API of SO Independently.
Do that now.

It turns out that the fixup from vlv_fixup_mipi_sequences() is necessary
for some DSI panel's with version 2 mipi-sequences too.
Specifically the Acer Iconia One 8 A1-840 (not to be confused with the
A1-840FHD which is different) has the following sequences:
BDB block 53 (1284 bytes) - MIPI sequence block:
Sequence block version v2
Panel 0 *
Sequence 2 - MIPI_SEQ_INIT_OTP
GPIO index 9, source 0, set 0 (0x00)
Delay: 50000 us
GPIO index 9, source 0, set 1 (0x01)
Delay: 6000 us
GPIO index 9, source 0, set 0 (0x00)
Delay: 6000 us
GPIO index 9, source 0, set 1 (0x01)

Send DCS: Port A, VC 0, LP, Type 39, Length 5, Data ff aa 55 a5 80
Send DCS: Port A, VC 0, LP, Type 39, Length 3, Data 6f 11 00
...
Send DCS: Port A, VC 0, LP, Type 05, Length 1, Data 29
Delay: 120000 us
Sequence 4 - MIPI_SEQ_DISPLAY_OFF
Send DCS: Port A, VC 0, LP, Type 05, Length 1, Data 28
Delay: 105000 us
Send DCS: Port A, VC 0, LP, Type 05, Length 2, Data 10 00
Delay: 10000 us
Sequence 5 - MIPI_SEQ_ASSERT_RESET
Delay: 10000 us
GPIO index 9, source 0, set 0 (0x00)
Notice how there is no MIPI_SEQ_DEASSERT_RESET, instead the deassert
is done at the beginning of MIPI_SEQ_INIT_OTP, which is exactly what
the fixup from vlv_fixup_mipi_sequences() fixes up.
Extend it to also apply to v2 sequences, this fixes the panel not working
on the Acer Iconia One 8 A1-840.

Install beacon protection keys in hardware for AP modes only if hardware
supports it, as indicated by the WMI service bit
WMI_TLV_SERVICE_BEACON_PROTECTION_SUPPORT. Allow keyidx up to 7, since
beacon protection uses keyidx 6 and 7.
Control this feature by setting bit 0 of feature_enable_bitmap when sending
the WMI_BCN_TMPL_CMDID command to firmware.
Check for the beacon protection enabled bit in both tx and non-tx profiles
for MBSSID cases. If set in either profile, enable the beacon protection
feature in firmware for transmitted vif.

Packets delivered to mac80211 from the WBM error path currently do not
have the RX_FLAG_SKIP_MONITOR flag set in status->flag. As a result,
mac80211 performs unnecessary monitor mode checks on each packet, even
though these packets are not intended for monitor mode processing.
In regular rx path, this flag is explicitly set to avoid such overhead.
Align the WBM error path behavior by setting RX_FLAG_SKIP_MONITOR to
prevent redundant per-packet checks in mac80211.

In order to ensure the HTT DebugFS structs shared with firmware have
matching alignment, the structs should be packed. Most of the structs
are correctly packed, however the following are not:
ath12k_htt_tx_pdev_rate_stats_tlv
ath12k_htt_rx_pdev_rate_stats_tlv
ath12k_htt_rx_pdev_rate_ext_stats_tlv
So pack those structs.

The maximum bandwidth an interface can operate in is defined by the
configured country. However, currently, it is able to operate in
bandwidths greater than the allowed bandwidth. For example,
the Central African Republic (CF) supports a maximum bandwidth of 40 MHz
in both the 2 GHz and 5 GHz bands, but an interface is still able to
operate in bandwidths higher than 40 MHz. This issue arises because the
regulatory rules in the regd are not updated with these restrictions
received from firmware on the maximum bandwidth.
Hence, update the regulatory rules with unsupported bandwidth flags based
on the maximum bandwidth to ensure compliance with country-specific
regulations.

Before each I2C transfer using DMA, the I2C buffer is DMA'pped to make
sure the memory buffer is DMA'able. This is handle in the function
`stm32_i2c_prep_dma_xfer()`.
If the transfer fails for any reason the I2C buffer must be unmap.
Use the dma_callback to factorize the code and fix this issue.
Note that the `stm32f7_i2c_dma_callback()` is now called in case of DMA
transfer success and error and that the `complete()` on the dma_complete
completion structure is done inconditionnally in case of transfer
success or error as well as the `dmaengine_terminate_async()`.
This is allowed as a `complete()` in case transfer error has no effect
as well as a `dmaengine_terminate_async()` on a transfer success.
Also fix the unneeded cast and remove not more needed variables.

RQTs (Receive Queue Table) should redirect traffic to the channels' RQs
when they're active. Otherwise, redirect to the designated "drop RQ".
RQTs are created in "inactive" state, pointing to the "drop RQ".
In activate and de-activate flows, do not "deactivate" the rest of RQTs
(beyond the num of channels), as they are already inactive.
This cuts down unnecessary execution of FW commands (MODIFY_RQT), and
improves the latency of open/close channels or configuration change.

The VLAN insertion capability (`wqe_vlan_insert`) was never enabled on
all mlx5 devices. When VLAN TX offload is advertised but this
capability is not supported, the driver uses inline headers to insert
the VLAN tag.
To support this, the driver used to set the
`MLX5E_SQ_STATE_VLAN_NEED_L2_INLINE` bit to enforce L2 inline mode
when `wqe_vlan_insert` was not supported. Since the capability is
disabled on all devices, this logic was always active, and the SQ flag
has become redundant. L2 inline is enforced unconditionally for
VLAN-tagged packets.
The `skb_vlan_tag_present()` check in the else-if block of
`mlx5e_sq_xmit_wqe()` is never true by this point in the TX flow,
as the VLAN tag has already been inserted by the driver using inline
headers. As a result, this code is never executed.
Remove the redundant SQ state, dead VLAN insertion code block, and
related logic.

Broadcom PHYs featuring the BroadR-Reach two-wire link mode are usually
capable to operate in simplified MII mode, without TXER, RXER, CRS and
COL signals as defined for the MII. The absence of COL signal makes
half-duplex link modes impossible, however, the BroadR-Reach modes are
all full-duplex only.
Depending on the IC encapsulation, there exist MII-Lite-only PHYs such
as bcm54811 in MLP. The PHY itself is hardware-strapped to select among
multiple RGMII and MII-Lite modes, but the MII-Lite mode must be also
activated by software.
Add MII-Lite activation for bcm5481x PHYs.

Some Broadcom PHYs are capable to operate in simplified MII mode,
without TXER, RXER, CRS and COL signals as defined for the MII.
The MII-Lite mode can be used on most Ethernet controllers with full
MII interface by just leaving the input signals (RXER, CRS, COL)
inactive. The absence of COL signal makes half-duplex link modes
impossible but does not interfere with BroadR-Reach link modes on
Broadcom PHYs, because they are all full-duplex only.
Add MII-Lite interface mode, especially for Broadcom two-wire PHYs.

All memory in GVE is currently allocated without regard for the NUMA
node of the device. Because access to NUMA-local memory access is
significantly cheaper than access to a remote node, this change attempts
to ensure that page frags used in the RX path, including page pool
frags, are allocated on the NUMA node local to the gVNIC device. Note
that this attempt is best-effort. If necessary, the driver will still
allocate non-local memory, as __GFP_THISNODE is not passed. Descriptor
ring allocations are not updated, as dma_alloc_coherent handles that.
This change also modifies the IRQ affinity setting to only select CPUs
from the node local to the device, preserving the behavior that TX and
RX queues of the same index share CPU affinity.

The current logic in nicvf_change_mtu() writes the new MTU to
netdev->mtu using WRITE_ONCE() before verifying if the hardware
update succeeds. However on hardware update failure, it attempts
to revert to the original MTU using a direct assignment
(netdev->mtu = orig_mtu)
which violates the intended of WRITE_ONCE protection introduced in
commit 1eb2cded45b3 ("net: annotate writes on dev->mtu from
ndo_change_mtu()")
Additionally, WRITE_ONCE(netdev->mtu, new_mtu) is unnecessarily
performed even when the device is not running.
Fix this by:
Only writing netdev->mtu after successfully updating the hardware.
Skipping hardware update when the device is down, and setting MTU
directly. Remove unused variable orig_mtu.
This ensures that all writes to netdev->mtu are consistent with
WRITE_ONCE expectations and avoids unintended state corruption
on failure paths.

Add support to get/set frequency on pins. The frequency for input
pins (references) is computed in the device according this formula:
freq = base_freq * multiplier * (nominator / denominator)
where the base_freq comes from the list of supported base frequencies
and other parameters are arbitrary numbers. All these parameters are
16-bit unsigned integers.
The frequency for output pin is determined by the frequency of
synthesizer the output pin is connected to and divisor of the output
to which is the given pin belongs. The resulting frequency of the
P-pin and the N-pin from this output pair depends on the signal
format of this output pair.
The device supports so-called N-divided signal formats where for the
N-pin there is an additional divisor. The frequencies for both pins
from such output pair are computed:
P-pin-freq = synth_freq / output_div
N-pin-freq = synth_freq / output_div / n_div
For other signal-format types both P and N pin have the same frequency
based only synth frequency and output divisor.
Implement output pin callbacks to get and set frequency. The frequency
setting for the output non-N-divided signal format is simple as we have
to compute just new output divisor. For N-divided formats it is more
complex because by changing of output divisor we change frequency for
both P and N pins. In this case if we are changing frequency for P-pin
we have to compute also new N-divisor for N-pin to keep its current
frequency. From this and the above it follows that the frequency of
the N-pin cannot be higher than the frequency of the P-pin and the
callback must take this limitation into account.

Implement input pin state setting when the DPLL is running in automatic
mode. Unlike manual mode, the DPLL mode switching is not used here and
the implementation uses special priority value (15) to make the given
pin non-selectable.
When the user sets state of the pin as disconnected the driver
internally sets its priority in HW to 15 that prevents the DPLL to
choose this input pin. Conversely, if the pin status is set to
selectable, the driver sets the pin priority in HW to the original saved
value.

Although the pin priority make sense only if the DPLL is running in

can run in automatic mode while the other one not.

Implement input pin state setting if the DPLL is running in manual mode.
The driver indicates manual mode if the DPLL mode is one of ref-lock,
forced-holdover, freerun.
Use these modes to implement input pin state change between connected
and disconnected states. When the user set the particular pin as
connected the driver marks this input pin as forced reference and
switches the DPLL mode to ref-lock. When the use set the pin as
disconnected the driver switches the DPLL to freerun or forced holdover
mode. The switch to holdover mode is done if the DPLL has holdover
capability (e.g is currently locked with holdover acquired).

Enumerate all available DPLL channels and registers a DPLL device for
each of them. Check all input references and outputs and register
DPLL pins for them.
Number of registered DPLL pins depends on configuration of references
and outputs. If the reference or output is configured as differential
one then only one DPLL pin is registered. Both references and outputs
can be also disabled from firmware configuration and in this case
no DPLL pins are registered.
All registrable references are registered to all available DPLL devices
with exception of DPLLs that are configured in NCO (numerically
controlled oscillator) mode. In this mode DPLL channel acts as PHC and
cannot be locked to any reference.
Device outputs are connected to one of synthesizers and each synthesizer
is driven by some DPLL channel. So output pins belonging to given output
are registered to DPLL device that drives associated synthesizer.
Finally add kworker task to monitor async changes on all DPLL channels
and input pins and to notify about them DPLL core. Output pins are not
monitored as their parameters are not changed asynchronously by the
device.
