Add "aspeed,ast2700-mdio" compatible to the binding schema with a fallback
to "aspeed,ast2600-mdio".
Although the MDIO controller on AST2700 is functionally the same as the
one on AST2600, it's good practice to add a SoC-specific compatible for
new silicon. This allows future driver updates to handle any 2700-specific
integration issues without requiring devicetree changes or complex
runtime detection logic.
For now, the driver continues to bind via the existing
"aspeed,ast2600-mdio" compatible, so no driver changes are needed.

swp_l4_csum_mode controls how L4 transmit checksums are computed when
using Software Parser (SWP) hints for header locations.
Supported values:
1. default: device will choose between full_csum or l4_only. Driver
will discover the device's choice during initialization.
2. full_csum: calculate L4 checksum with the pseudo-header.
3. l4_only: calculate L4 checksum without the pseudo-header. Only
available when swp_l4_csum_mode_l4_only is set in
mlx5_ifc_nv_sw_offload_cap_bits.
Note that 'default' might be returned from the device and passed to
userspace, and it might also be set during a
devlink_param::reset_default() call, but attempts to set a value of
default directly with param-set will be rejected.
The l4_only setting is a dependency for PSP initialization in
mlx5e_psp_init().

Support querying and resetting to default param values.
Introduce two new devlink netlink attrs:
DEVLINK_ATTR_PARAM_VALUE_DEFAULT and
DEVLINK_ATTR_PARAM_RESET_DEFAULT. The former is used to contain an
optional parameter value inside of the param_value nested
attribute. The latter is used in param-set requests from userspace to
indicate that the driver should reset the param to its default value.
To implement this, two new functions are added to the devlink driver
api: devlink_param::get_default() and
devlink_param::reset_default(). These callbacks allow drivers to
implement default param actions for runtime and permanent cmodes. For
driverinit params, the core latches the last value set by a driver via
devl_param_driverinit_value_set(), and uses that as the default value
for a param.
Because default parameter values are optional, it would be impossible
to discern whether or not a param of type bool has default value of
false or not provided if the default value is encoded using a netlink
flag type. For this reason, when a DEVLINK_PARAM_TYPE_BOOL has an
associated default value, the default value is encoded using a u8
type.

Since commit 1b255e1bea ("tools: ynl: add ipv4-or-v6 display hint"), we
can display either IPv4 or IPv6 addresses for a single field based on the
address family. However, most dual-stack fields still use the ipv4 display
hint. This update changes them to use the new ipv4-or-v6 display hint and
converts IPv4-only fields to use the u32 type.

When a flow has many drops (1 % or more), and small RTT, adding 100 usec
before sending SACK stalls the sender relying on getting SACK
fast enough to keep the pipe busy.
Decrease the default to 10 usec.

Adds DEVLINK_ESWITCH_MODE_SWITCHDEV_INACTIVE attribute to UAPI and
documentation.
Before having traffic flow through an eswitch, a user may want to have the
ability to block traffic towards the FDB until FDB is fully programmed and
the user is ready to send traffic to it. For example: when two eswitches
are present for vports in a multi-PF setup, one eswitch may take over the
traffic from the other when the user chooses.
Before this take over, a user may want to first program the inactive
eswitch and then once ready redirect traffic to this new eswitch.
switchdev modes transition semantics:
legacy->switchdev_inactive: Create switchdev mode normally, traffic not
allowed to flow yet.
switchdev_inactive->switchdev: Enable traffic to flow.
switchdev->switchdev_inactive: Block traffic on the FDB, FDB and
representros state and content is preserved.
When eswitch is configured to this mode, traffic is ignored/dropped on
this eswitch FDB, while current configuration is kept, e.g FDB rules and
netdev representros are kept available, FDB programming is allowed.
Example:
# start inactive switchdev
devlink dev eswitch set pci/0000:08:00.1 mode switchdev_inactive
# setup TC rules, representors etc ..
# activate
devlink dev eswitch set pci/0000:08:00.1 mode switchdev

TCP SACK compression has been added in 2018 in commit
5d9f4262b7 ("tcp: add SACK compression").
It is working great for WAN flows (with large RTT).
Wifi in particular gets a significant boost _when_ ACK are suppressed.
Add a new sysctl so that we can tune the very conservative 5 % value
that has been used so far in this formula, so that small RTT flows
can benefit from this feature.
delay = min ( 5 % of RTT, 1 ms)
This patch adds new tcp_comp_sack_rtt_percent sysctl
to ease experiments and tuning.
Given that we cap the delay to 1ms (tcp_comp_sack_delay_ns sysctl),
set the default value to 33 %.
Quoting Neal Cardwell ( https://lore.kernel.org/netdev/CADVnQymZ1tFnEA1Q=vtECs0=Db7zHQ8=+WCQtnhHFVbEOzjVnQ@mail.gmail.com/ )
The rationale for 33% is basically to try to facilitate pipelining,
where there are always at least 3 ACKs and 3 GSO/TSO skbs per SRTT, so
that the path can maintain a budget for 3 full-sized GSO/TSO skbs "in
flight" at all times:
+ 1 skb in the qdisc waiting to be sent by the NIC next
+ 1 skb being sent by the NIC (being serialized by the NIC out onto the wire)
+ 1 skb being received and aggregated by the receiver machine's
aggregation mechanism (some combination of LRO, GRO, and sack
compression)
Note that this is basically the same magic number (3) and the same
rationales as:
(a) tcp_tso_should_defer() ensuring that we defer sending data for no
longer than cwnd/tcp_tso_win_divisor (where tcp_tso_win_divisor = 3),
and
(b) bbr_quantization_budget() ensuring that cwnd is at least 3 GSO/TSO
skbs to maintain pipelining and full throughput at low RTTs

GSW1xx switches which are based on the same hardware IP but connected
via MDIO instead of being memory-mapped.
Add compatible strings for MaxLinear GSW120, GSW125, GSW140, GSW141,
and GSW145 switches and adjust the schema to handle the different
connection methods with conditional properties.
Add MaxLinear GSW125 example showing MDIO-connected configuration.

Add support for standard tx-internal-delay-ps and rx-internal-delay-ps
properties on port nodes to allow fine-tuning of RGMII clock delays.
The GSWIP switch hardware supports delay values in 500 picosecond
increments from 0 to 3500 picoseconds, with a post-reset default of 2000
picoseconds for both TX and RX delays. The driver currently sets the
delay to 0 in case the PHY is setup to carry out the delay by the
corresponding interface modes ("rgmii-id", "rgmii-rxid", "rgmii-txid").
This corresponds to the driver changes that allow adjusting MII delays
using Device Tree properties instead of relying solely on the PHY
interface mode.

Add support for the maxlinear,rmii-refclk-out boolean property on port
nodes to configure the RMII reference clock to be an output rather than
an input.
This property is only applicable for ports in RMII mode and allows the
switch to provide the reference clock for RMII-connected PHYs instead
of requiring an external clock source.
This corresponds to the driver changes that read this Device Tree
property to configure the RMII clock direction.

Currently the i40e driver enforces its own internally calculated per-VF MAC
filter limit, derived from the number of allocated VFs and available
hardware resources. This limit is not configurable by the administrator,
which makes it difficult to control how many MAC addresses each VF may
use.
This patch adds support for the new generic devlink runtime parameter
"max_mac_per_vf" which provides administrators with a way to cap the
number of MAC addresses a VF can use:
- When the parameter is set to 0 (default), the driver continues to use
its internally calculated limit.
- When set to a non-zero value, the driver applies this value as a strict
cap for VFs, overriding the internal calculation.
Important notes:
- The configured value is a theoretical maximum. Hardware limits may
still prevent additional MAC addresses from being added, even if the
parameter allows it.
- Since MAC filters are a shared hardware resource across all VFs,
setting a high value may cause resource contention and starve other
VFs.
- This change gives administrators predictable and flexible control over
VF resource allocation, while still respecting hardware limitations.

Introduce the userspace entry point for PHY MSE diagnostics via
ethtool netlink. This exposes the core API added previously and
returns both capability information and one or more snapshots.
Userspace sends ETHTOOL_MSG_MSE_GET. The reply carries:
- ETHTOOL_A_MSE_CAPABILITIES: scale limits and timing information
- ETHTOOL_A_MSE_CHANNEL_* nests: one or more snapshots (per-channel
if available, otherwise WORST, otherwise LINK)
Link down returns -ENETDOWN.
Changes:
- YAML: add attribute sets (mse, mse-capabilities, mse-snapshot)
and the mse-get operation
- UAPI (generated): add ETHTOOL_A_MSE_* enums and message IDs,
ETHTOOL_MSG_MSE_GET/REPLY
- ethtool core: add net/ethtool/mse.c implementing the request,
register genl op, and hook into ethnl dispatch
- docs: document MSE_GET in ethtool-netlink.rst
The include/uapi/linux/ethtool_netlink_generated.h is generated
from Documentation/netlink/specs/ethtool.yaml.

Add a new state NAPI_STATE_THREADED_BUSY_POLL to the NAPI state enum to
enable and disable threaded busy polling.
When threaded busy polling is enabled for a NAPI, enable
NAPI_STATE_THREADED also.
When the threaded NAPI is scheduled, set NAPI_STATE_IN_BUSY_POLL to
signal napi_complete_done not to rearm interrupts.
Whenever NAPI_STATE_THREADED_BUSY_POLL is unset, the
NAPI_STATE_IN_BUSY_POLL will be unset, napi_complete_done unsets the
NAPI_STATE_SCHED_THREADED bit also, which in turn will make the kthread
go to sleep.
