The addr cam H2C command is to tell firmware the addr related info.
For RTL8922D and RTL8922A after firmware version 0.35.84.0, the addr cam
must be updated with update mode to avoid clearing previously set

The existing flow is doing BB pre-init before downloading BB MCU firmware,
because existing chip RTL8922A has BB MCU. However, the coming chips don't
have this, and BB pre-init configuring registers can affect downloading
WiFi-CPU firmware. Therefore, calling BB pre-init afterward for new coming
chips without BB MCU.
For existing WiFi 6 chips, no BB pre-init. For RTL8922A, don't change
the logic.

In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through
nl80211_tx_control_port() and triggers wake_tx_queue() in the driver.
Then, it sends nl80211_new_key() to configure a new key in mac80211.
However, in wake_tx_queue(), a workqueue is used to process the TX packet,
which might cause the driver to process the EAPOL packet later than
nl80211_new_key(). This results in the EAPOL packet 4/4 being transmitted
with the new key and IV, causing it to be dropped by the AP. Therefore,
needs to flush TX queue before deleting the old key to ensure that the
EAPOL 4/4 packet is transmitted using the old key.

mentions a use case involving callback adjust_link of struct
dsa_switch_driver. This struct doesn't exist any longer, and in general
usage of the legacy fixed PHY has been removed from DSA with the switch
to phylink.
Note: Supported and advertised modes are now set by phy_probe() when
the fixed PHY is attached to the netdev and bound to the genphy driver.

fbnic supports pause frames. When pause frames are enabled presumably
user expects lossless operation from the NIC. Make sure we configure
RDE (Rx DMA Engine) to DROP_NEVER mode to avoid discards due to delays
in fetching Rx descriptors from the host.
While at it enable DROP_NEVER when NIC only has a single queue
configured. In this case the NIC acts as a FIFO so there's no risk
of head-of-line blocking other queues by making RDE wait. If pause
is disabled this just moves the packet loss from the DMA engine to
the Rx buffer.
Remove redundant call to fbnic_config_drop_mode_rcq(), introduced by
commit 0cb4c0a13723 ("eth: fbnic: Implement Rx queue
alloc/start/stop/free"). This call does not add value as
fbnic_enable_rcq(), which is called immediately afterward, already
handles this.
Although we do not support autoneg at this time, preserve tx_pause in
.mac_link_up instead of fbnic_phylink_get_pauseparam()

Commit 84eaf4359c36 ("net: ethtool: add get_rx_ring_count callback to
optimize RX ring queries") added specific support for GRXRINGS callback,
simplifying .get_rxnfc.
Remove the handling of GRXRINGS in .get_rxnfc() by moving it to the new
.get_rx_ring_count() for both the mlx5 ethernet and IPoIB drivers.
The ETHTOOL_GRXRINGS handling was previously kept in .get_rxnfc() to
support "ethtool -x" when CONFIG_MLX5_EN_RXNFC=n. With the new
dedicated .get_rx_ring_count() callback, this is no longer necessary.
This simplifies the RX ring count retrieval and aligns mlx5 with the new
ethtool API for querying RX ring parameters.

accessing data

gs_host_frame. The length of the data after the header depends on the

The driver lacks the cleanup of failed transfers of URBs. This reduces the
number of available URBs per error by 1. This leads to reduced performance
and ultimately to a complete stop of the transmission.
If the sending of a bulk URB fails do proper cleanup:
- increase netdev stats
- mark the echo_sbk as free
- free the driver's context and do accounting
- wake the send queue

The `kvaser_usb_leaf_wait_cmd()` and `kvaser_usb_leaf_read_bulk_callback`
functions contain logic to zero-length commands. These commands are used
to align data to the USB endpoint's wMaxPacketSize boundary.
The driver attempts to skip these placeholders by aligning the buffer
position `pos` to the next packet boundary using `round_up()` function.
However, if zero-length command is found exactly on a packet boundary
(i.e., `pos` is a multiple of wMaxPacketSize, including 0), `round_up`
function will return the unchanged value of `pos`. This prevents `pos`
to be increased, causing an infinite loop in the parsing logic.
This patch fixes this in the function by using `pos + 1` instead.
This ensures that even if `pos` is on a boundary, the calculation is
based on `pos + 1`, forcing `round_up()` to always return the next
aligned boundary.

Commit dc82a33297fc ("veth: apply qdisc backpressure on full ptr_ring to
reduce TX drops") introduced a race condition that can lead to a permanently
stalled TXQ. This was observed in production on ARM64 systems (Ampere Altra
Max).
The race occurs in veth_xmit(). The producer observes a full ptr_ring and
stops the queue (netif_tx_stop_queue()). The subsequent conditional logic,
intended to re-wake the queue if the consumer had just emptied it (if
(__ptr_ring_empty(...)) netif_tx_wake_queue()), can fail. This leads to a
"lost wakeup" where the TXQ remains stopped (QUEUE_STATE_DRV_XOFF) and
traffic halts.
This failure is caused by an incorrect use of the __ptr_ring_empty() API
from the producer side. As noted in kernel comments, this check is not
guaranteed to be correct if a consumer is operating on another CPU. The
empty test is based on ptr_ring->consumer_head, making it reliable only for
the consumer. Using this check from the producer side is fundamentally racy.
This patch fixes the race by adopting the more robust logic from an earlier
version V4 of the patchset, which always flushed the peer:
(1) In veth_xmit(), the racy conditional wake-up logic and its memory barrier
are removed. Instead, after stopping the queue, we unconditionally call
__veth_xdp_flush(rq). This guarantees that the NAPI consumer is scheduled,
making it solely responsible for re-waking the TXQ.
This handles the race where veth_poll() consumes all packets and completes
NAPI *before* veth_xmit() on the producer side has called netif_tx_stop_queue.
The __veth_xdp_flush(rq) will observe rx_notify_masked is false and schedule
NAPI.
(2) On the consumer side, the logic for waking the peer TXQ is moved out of
veth_xdp_rcv() and placed at the end of the veth_poll() function. This
placement is part of fixing the race, as the netif_tx_queue_stopped() check
must occur after rx_notify_masked is potentially set to false during NAPI
completion.
This handles the race where veth_poll() consumes all packets, but haven't
finished (rx_notify_masked is still true). The producer veth_xmit() stops the
TXQ and __veth_xdp_flush(rq) will observe rx_notify_masked is true, meaning
not starting NAPI. Then veth_poll() change rx_notify_masked to false and
stops NAPI. Before exiting veth_poll() will observe TXQ is stopped and wake
it up.

Add support for the PHY LED controller in the MSCC VSC85xx driver. The
implementation provides LED brightness and hardware control through the
LED subsystem and integrates with the standard 'netdev' trigger.
Introduce new register definitions for the LED behavior register
(MSCC_PHY_LED_BEHAVIOR = 30) and the LED combine disable bits, which
control whether LEDs indicate link-only or combined link and activity
status. Implement a helper, vsc8541_led_combine_disable_set(), to update
these bits safely using phy_modify().
Add support for LED brightness control and hardware mode configuration.
The new callbacks implement the standard LED class operations, allowing
user control through sysfs. The brightness control maps to PHY LED force
on/off modes. The hardware control get and set functions translate
between the PHY-specific LED mode encodings and the LED subsystem
TRIGGER_NETDEV_* rules.
The combine feature is managed automatically based on the selected
rules. When both RX and TX activity are disabled, the combine feature is
turned off, causing LEDs to indicate link-only status. When either RX or
TX activity is enabled, the combine feature remains active and LEDs
indicate combined link and activity.
Register the LED callbacks for all VSC85xx PHY variants so that the LED
subsystem can manage their indicators consistently. Existing device tree
LED configuration and default behavior are preserved.

Unify the probe implementations of the VSC85xx PHY family into a single
vsc85xx_probe_common() helper. The existing probe functions for the
vsc85xx, vsc8514, vsc8574, and vsc8584 variants contained almost
identical initialization logic, differing only in configuration
parameters such as the number of LEDs, supported LED modes, hardware
statistics, and PTP support.
Introduce a vsc85xx_probe_config structure to describe the per-variant
parameters, and move all common setup code into the shared helper. Each
variant's probe function now defines a constant configuration instance
and calls vsc85xx_probe_common().
Also mark the default LED mode array parameter as const to match its
usage.

The vsc85xx_led_cntl_set() function currently performs a manual
read-modify-write sequence protected by the PHY lock to update the
LED mode register (MSCC_PHY_LED_MODE_SEL).
Replace this sequence with a call to phy_modify(), which already
handles read-modify-write operations with proper locking inside
the PHY core.

The function mlxsw_sp_flower_stats() calls mlxsw_sp_acl_ruleset_get() to
obtain a ruleset reference. If the subsequent call to
mlxsw_sp_acl_rule_lookup() fails to find a rule, the function returns
an error without releasing the ruleset reference, causing a memory leak.
Fix this by using a goto to the existing error handling label, which
calls mlxsw_sp_acl_ruleset_put() to properly release the reference.

The ->setup() method implemented by dwmac-loongson and dwmac-sun8i
allocate the mac_device_info structure, as does stmmac_hwif_init().
This makes no sense.
Have stmmac_hwif_init() always allocate this structure, and pass it to
the ->setup() method to initialise when it is provided. Rename this
method to "mac_setup" to more accurately describe what it is doing.

stmmac_reset() takes the stmmac_priv and an ioaddr. It has one call
site, which passes the priv pointer, and dereferences priv for the
ioaddr.
stmmac_reset() then checks whether priv is NULL. If it was, the caller
would have oopsed. Remove the checks for NULL, and move the dereference
for ioaddr into stmmac_reset().

The purpose of commit 703eec1b2422 ("virtio_net: fixing XDP for fully
checksummed packets handling") is to record the flags in advance, as
their value may be overwritten in the XDP case. However, the flags
recorded under big mode are incorrect, because in big mode, the passed
buf does not point to the rx buffer, but rather to the page of the
submitted buffer. This commit fixes this issue.
For the small mode, the commit c11a49d58ad2 ("virtio_net: Fix mismatched
buf address when unmapping for small packets") fixed it.

to use the ndo_hwtstamp callbacks.
Maud Spierings contributes a patch for the mcp251x driver that
converts it to use dev_err_probe().
The next 6 patches target the mcp251xfd driver and are by Gregor
Herburger and me. They add GPIO controller functionality to the
driver.
The final patch is by Chu Guangqing and fixes a typo in the bxcan
driver.

Use stmmac_get_phy_intf_sel() to decode the PHY interface mode to the
phy_intf_sel value, validate the result and use that to set the
control register to select the operating mode for the DWMAC core.
Note that this will allow GMII as well as MII as the phy_intf_sel
value is the same for both.

Convert dwmac-visconti to use the PHY_INTF_SEL_x definitions. The
original definitions used constant 0, BIT(0) (==1) and BIT(2) (==4)
to define these, but the values of the bits corresponds with the
PHY_INTF_SEL_x values, so it is highly likely that these are not
individual bits, but the PHY_INTF_SEL_x bitfield.
This removes this incorrect use of BIT().
