HDS options(tcp-data-split, hds-thresh) have dependencies between other
features like XDP. Basic dependencies are checked in the core API.
netdevsim is very useful to check basic dependencies.
The default tcp-data-split mode is UNKNOWN but netdevsim driver
returns ENABLED when ethtool dumps tcp-data-split mode.
The default value of HDS threshold is 0 and the maximum value is 1024.
ethtool shows like this.
ethtool -g eni1np1

Pre-set maximums:
...
HDS thresh: 1024

TCP data split: on

The bnxt_en driver has configured the hds_threshold value automatically
when TPA is enabled based on the rx-copybreak default value.
Now the hds-thresh ethtool command is added, so it adds an
implementation of hds-thresh option.
Configuration of the hds-thresh is applied only when
the tcp-data-split is enabled. The default value of
hds-thresh is 256, which is the default value of
rx-copybreak, which used to be the hds_thresh value.
The maximum hds-thresh is 1023.
# Example:
# ethtool -G enp14s0f0np0 tcp-data-split on hds-thresh 256
# ethtool -g enp14s0f0np0

NICs that uses bnxt_en driver supports tcp-data-split feature by the
name of HDS(header-data-split).
But there is no implementation for the HDS to enable by ethtool.
Only getting the current HDS status is implemented and The HDS is just
automatically enabled only when either LRO, HW-GRO, or JUMBO is enabled.
The hds_threshold follows rx-copybreak value. and it was unchangeable.
This implements `ethtool -G <interface name> tcp-data-split <value>`
command option.
The value can be <on> and <auto>.
The value is <auto> and one of LRO/GRO/JUMBO is enabled, HDS is
automatically enabled and all LRO/GRO/JUMBO are disabled, HDS is
automatically disabled.
HDS feature relies on the aggregation ring.
So, if HDS is enabled, the bnxt_en driver initializes the aggregation ring.
This is the reason why BNXT_FLAG_AGG_RINGS contains HDS condition.

The bnxt_en driver supports rx-copybreak, but it couldn't be set by
userspace. Only the default value(256) has worked.
This patch makes the bnxt_en driver support following command.
`ethtool --set-tunable <devname> rx-copybreak <value> ` and
`ethtool --get-tunable <devname> rx-copybreak`.
By this patch, hds_threshol is set to the rx-copybreak value.
But it will be set by `ethtool -G eth0 hds-thresh N`
in the next patch.

The lan969x switch device supports manual frame injection and extraction
to and from the switch core, using a number of injection and extraction
queues. This technique is currently supported, but delivers poor
performance compared to Frame DMA (FDMA).
This lan969x implementation of FDMA, hooks into the existing FDMA for
Sparx5, but requires its own RX and TX handling, as lan969x does not
support the same native cache coherency that Sparx5 does. Effectively,
this means that we are going to use the DMA mapping API for mapping and
unmapping TX buffers. The RX loop will utilize the page pool API for
efficient RX handling. Other than that, the implementation is largely
the same, and utilizes the FDMA library for DCB and DB handling.
Some numbers:

lan969x and therefore need to introduce new ops for FDMA functions:
init, deinit, xmit and poll. Assign the Sparx5 equivalents for these and
update the code throughout. Also add a 'struct net_device' argument to
the xmit() function, as we will be needing that for lan969x.

The function sparx5_fdma_tx_activate() is responsible for configuring
the TX FDMA instance and activating the channel. TX activation has
previously been done in the xmit() function, when the first frame is
transmitted. Now that we have separate functions for starting and
stopping the FDMA, it seems reasonable to move the TX activation to the
start function. This change has no implications on the functionality.

The two functions: sparx5_fdma_{start(),stop()} are responsible for a
number of things, namely: allocation and initialization of FDMA buffers,
activation FDMA channels in hardware and activation of the NAPI
instance.
This patch splits the buffer allocation and initialization into init and
deinit functions, and the channel and NAPI activation into start and
stop functions. This serves two purposes: 1) the start() and stop()
functions can be reused for lan969x and 2) prepares for future MTU
change support, where we must be able to stop and start the FDMA
channels and NAPI instance, without free'ing and reallocating the FDMA
buffers.

Fix use of DIV_ROUND_CLOSEST where a possibly negative value is divided
by an unsigned type by casting the unsigned type to the signed type of
the same size (st->r_sense_uohm[channel] has type of u32).
The docs on the DIV_ROUND_CLOSEST macro explain that dividing a negative
value by an unsigned type is undefined behavior. The actual behavior is
that it converts both values to unsigned before doing the division, for
example:
int ret = DIV_ROUND_CLOSEST(-100, 3U);
results in ret == 1431655732 instead of -33.

w/o inband
On a port with SGMII fixed-link at SPEED_1000, DW_VR_MII_DIG_CTRL1 gets
set to 0x2404. This is incorrect, because bit 2 (DW_VR_MII_DIG_CTRL1_2G5_EN)
is set.
It comes from the previous write to DW_VR_MII_AN_CTRL, because the "val"
variable is reused and is dirty. Actually, its value is 0x4, aka
FIELD_PREP(DW_VR_MII_PCS_MODE_MASK, DW_VR_MII_PCS_MODE_C37_SGMII).
Resolve the issue by clearing "val" to 0 when writing to a new register.
After the fix, the register value is 0x2400.
Prior to the blamed commit, when the read-modify-write was open-coded,
the code saved the content of the DW_VR_MII_DIG_CTRL1 register in the
"ret" variable.

Instead of marking individual interrupts as safe to be migrated in
arbitrary contexts, mark the interrupt chips, which require the interrupt
to be moved in actual interrupt context, with the new IRQCHIP_MOVE_DEFERRED
flag. This makes more sense because this is a per interrupt chip property
and not restricted to individual interrupts.
That flips the logic from the historical opt-out to a opt-in model. This is
simpler to handle for other architectures, which default to unrestricted
affinity setting. It also allows to cleanup the redundant core logic
significantly.
All interrupt chips, which belong to a top-level domain sitting directly on
top of the x86 vector domain are marked accordingly, unless the related
setup code marks the interrupts with IRQ_MOVE_PCNTXT, i.e. XEN.
No functional change intended.

This backend requests a NACK from the controller driver when it detects
an error. If that request gets ignored from some reason, subsequent
accesses will wrongly be handled OK. To fix this, an error now changes
the state machine, so the backend will report NACK until a STOP
condition has been detected. This make the driver more robust against
controllers which will sadly apply the NACK not to the current byte but
the next one.

When this controller is a target, the NACK handling had two issues.
First, the return value from the backend was not checked on the initial
WRITE_REQUESTED. So, the driver missed to send a NACK in this case.
Also, the NACK always arrives one byte late on the bus, even in the
WRITE_RECEIVED case. This seems to be a HW issue. We should then not
rely on the backend to correctly NACK the superfluous byte as well. Fix
both issues by introducing a flag which gets set whenever the backend
requests a NACK and keep sending it until we get a STOP condition.

This reverts commit 98d1fb94ce75f39febd456d6d3cbbe58b6678795.
The commit uses data nbits instead of addr nbits for dummy phase. This
causes a regression for all boards where spi-tx-bus-width is smaller
than spi-rx-bus-width. It is a common pattern for boards to have
spi-tx-bus-width == 1 and spi-rx-bus-width > 1. The regression causes
all reads with a dummy phase to become unavailable for such boards,
leading to a usually slower 0-dummy-cycle read being selected.
Most controllers' supports_op hooks call spi_mem_default_supports_op().
In spi_mem_default_supports_op(), spi_mem_check_buswidth() is called to
check if the buswidths for the op can actually be supported by the
board's wiring. This wiring information comes from (among other things)
the spi-{tx,rx}-bus-width DT properties. Based on these properties,
SPI_TX_* or SPI_RX_* flags are set by of_spi_parse_dt().
spi_mem_check_buswidth() then uses these flags to make the decision
whether an op can be supported by the board's wiring (in a way,
indirectly checking against spi-{rx,tx}-bus-width).
Now the tricky bit here is that spi_mem_check_buswidth() does:
if (op->dummy.nbytes &&
spi_check_buswidth_req(mem, op->dummy.buswidth, true))
return false;
The true argument to spi_check_buswidth_req() means the op is treated as
a TX op. For a board that has say 1-bit TX and 4-bit RX, a 4-bit dummy
TX is considered as unsupported, and the op gets rejected.
The commit being reverted uses the data buswidth for dummy buswidth. So
for reads, the RX buswidth gets used for the dummy phase, uncovering
this issue. In reality, a dummy phase is neither RX nor TX. As the name
suggests, these are just dummy cycles that send or receive no data, and
thus don't really need to have any buswidth at all.
Ideally, dummy phases should not be checked against the board's wiring
capabilities at all, and should only be sanity-checked for having a sane
buswidth value. Since we are now at rc7 and such a change might
introduce many unexpected bugs, revert the commit for now. It can be
sent out later along with the spi_mem_check_buswidth() fix.
Fixes: 98d1fb94ce75 ("mtd: spi-nor: core: replace dummy buswidth from addr to data")

ath.git patches for v6.14
This development cycle again featured multiple patchsets to ath12k to
support the new 802.11be MLO feature, this time including the device
grouping infrastructure, and the advertisement of MLO support to the
wireless core. However the MLO feature is still considered to be
incomplete.
In addition, there was the usual set of bug fixes and cleanups, mostly
in ath12k, but also in ath9k.

wiphy_unregister()/wiphy_free() has been recently decoupled from
wilc_netdev_cleanup() to fix a faulty error path in sdio/spi probe

The warning is triggered by the fact that there is still a
wireless_device linked to the wiphy we are unregistering, due to
wiphy_unregister() now being called after net device unregister (performed
in wilc_netdev_cleanup()). Fix this warning by moving wiphy_unregister()
after wilc_netdev_cleanup() is nominal paths (ie: driver removal).
wilc_netdev_cleanup() ordering is left untouched in error paths in probe
function because net device is not registered in those paths (so the
warning can not trigger), yet the wiphy can still be registered, and we
still some cleanup steps from wilc_netdev_cleanup().

For WCN6855, board ID specific NVM needs to be downloaded once board ID
is available, but the default NVM is always downloaded currently.
The wrong NVM causes poor RF performance, and effects user experience
for several types of laptop with WCN6855 on the market.
Fix by downloading board ID specific NVM if board ID is available.

The hdev->reset is never used now and the hdev->cmd_timeout actually
does reset. This patch changes the call path from
hdev->cmd_timeout -> vendor_cmd_timeout -> btusb_reset -> hdev->reset
, to
hdev->reset -> vendor_reset -> btusb_reset
Which makes it clear when we export the hdev->reset to a wider usage
e.g. allowing reset from sysfs.
This patch doesn't introduce any behavior change.

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
file.

The firmware-name property has been expanded to specify the names of NVM
and rampatch firmware for certain chips, such as the QCA6698 Bluetooth
chip. Although it shares the same IP core as the WCN6855, the QCA6698
has different RF components and RAM sizes, necessitating new firmware
files. This change allows for the configuration of NVM and rampatch in
DT.
Possible configurations:
firmware-name = QCA6698/hpnv21.bin, QCA6698/hpbtfw21.tlv;
firmware-name = QCA6698/hpnv21, QCA6698/hpbtfw21.tlv;

Different connectivity boards may be attached to the same platform. For
example, QCA6698-based boards can support either a two-antenna or
three-antenna solution, both of which work on the sa8775p-ride platform.
Due to differences in connectivity boards and variations in RF
performance from different foundries, different NVM configurations are
used based on the board ID.
Therefore, in the firmware-name property, if the NVM file has an
extension, the NVM file will be used. Otherwise, the system will first
try the .bNN (board ID) file, and if that fails, it will fall back to
the .bin file.
Possible configurations:
firmware-name = "QCA6698/hpnv21";
firmware-name = "QCA6698/hpnv21.bin";

When a Bluetooth raw socket is open, the HCI event related to SCO
connection changes are not dispatched to the hci_event module, and
the underlying Bluetooth controller's USB Interface 1 will not be
updated accordingly.
This patch adds `isoc_alt` sysfs attribute, allowing user space
to update the alternate setting of the USB interface alternate
setting as needed.
