net/sched: sch_cake: Fix incorrect qlen reduction in cake_drop
In cake_drop(), qdisc_tree_reduce_backlog() is used to update the qlen
and backlog of the qdisc hierarchy. Its caller, cake_enqueue(), assumes
that the parent qdisc will enqueue the current packet. However, this
assumption breaks when cake_enqueue() returns NET_XMIT_CN: the parent
qdisc stops enqueuing current packet, leaving the tree qlen/backlog
accounting inconsistent. This mismatch can lead to a NULL dereference
(e.g., when the parent Qdisc is qfq_qdisc).
This patch computes the qlen/backlog delta in a more robust way by
observing the difference before and after the series of cake_drop()
calls, and then compensates the qdisc tree accounting if cake_enqueue()
returns NET_XMIT_CN.
To ensure correct compensation when ACK thinning is enabled, a new

The cosmetic changes in this patch confirms that the spec is aligned
with the implementation. By using the generated version, it ensures
that they stay in sync.
Changes in the generated header:
* Trivial header guard rename.
* Trivial white space changes.
* Trivial comment changes.

* Drop __*_F_ALL constants (see [1]).
This patch adds a near[1] complete YNL specification for WireGuard,
documenting the protocol in a machine-readable format, rather than
comments in wireguard.h, and eases usage from C and non-C programming
languages alike.
The generated C library will be featured in a later patch, so in
this patch I will use the in-kernel python client for examples.
This makes the documentation in the UAPI header redundant, it is
therefore removed. The in-line documentation in the spec is based
on the existing comment in wireguard.h, and once released it will
be available in the kernel documentation at:

Vladimir Oltean says:
====================
DSA simple HSR offload
Provide a "simple" form of HSR offload for 8 DSA drivers (just the
NETIF_F_HW_HSR_DUP feature) based on the fact that their taggers use the
dsa_xmit_port_mask() function. This is in patches 6-13/15.
The helpers per se are introduced in patch 5/15, and documented in patch
15/15. Patch 14/15 is another small (and related) documentation update.
For HSR interlink ports the offloading rules are not quite so clear, and
for now we completely reject the offload. We can revise that once we see
a full offload implementation and understand what is needed.
To reject the offload, we need to know the port type, and patch 2/15
helps with that.
xrs700x is another driver which should have rejected offload based on
port type (patch 4/15). This is a bug fix submitted through net-next due
to the extra API required to fix it. If necessary, it could also be
picked up separately for backporting.
There is also patch 3/15, which makes the HSR offload like the others
supported by DSA: if we fall back to the software implementation, don't
call port_hsr_leave(), because by definition there won't be anything to
do.
A slightly unrelated change is patch 1/15, but I noticed this along the
way, and if I were to submit it separately, it would conflict with this
work (it would appear in patch 12/15's context).
Most of the driver additions are trivial. By far the most complex was
ocelot (which I could test). Microchip ksz (which I cannot test, and did
not patch) would also have some complexity. Essentially, ksz_hsr_join()
could fall back to a partial offload through the simple helpers, if the
full offload is not possible. But keeping track of which offload kind
was used is necessary later in ksz_hsr_leave(). This is left as homework
for interested developers.
With this patch set, one can observe a 50% reduction in transmitted
traffic over HSR interfaces.

Accelerate TX packet duplication with HSR rings.
This is only possible with the NPI-based "ocelot" tagging protocol, not
with "ocelot-8021q", because the latter does not use dsa_xmit_port_mask().
This has 2 implications:
- Depending on tagging protocol, we should set (or not set) the offload
feature flags. Switching tagging protocols is done with ports down, by
design. Additional calls to dsa_port_simple_hsr_join() can be put in
the ds->ops->change_tag_protocol() path, as I had originally tried,
but this would not work: dsa_user_setup_tagger() would later clear
the feature flag that we just set. So the additional call to
dsa_port_simple_hsr_join() should sit in the ds->ops->port_enable()
call.
- When joining a HSR ring and we are currently using "ocelot-8021q",
there are cases when we should return -EOPNOTSUPP (pessimistic) and
cases when we shouldn't (optimistic). In the pessimistic case, it is a
configuration that the port won't support even with the right tagging
protocol. Distinguishing between these 2 cases matters because if we
just return -EOPNOTSUPP regardless, we lose the dp->hsr_dev pointer
and can no longer replay the offload later for the optimistic case,
from felix_port_enable().
Vladimir Oltean [Sun, 30 Nov 2025 13:16:47 +0000 (15:16 +0200)]
net: dsa: add simple HSR offload helpers
It turns out that HSR offloads are so fine-grained that many DSA
switches can do a small part even though they weren't specifically
designed for the protocols supported by that driver (HSR and PRP).
Specifically NETIF_F_HW_HSR_DUP - it is simple packet duplication on
transmit, towards all (aka 2) ports members of the HSR device.
For many DSA switches, we know how to duplicate a packet, even though we
never typically use that feature. The transmit port mask from the
tagging protocol can have multiple bits set, and the switch should send
the packet once to every port with a bit set from that mask.
Nonetheless, not all tagging protocols are like this, and sometimes the
port is a single numeric value rather than a bit mask. For that reason,
and also because switches can sometimes change tagging protocols for
different ones, we need to make HSR offload helpers opt-in.
For devices that can do nothing else HSR-specific, we introduce
dsa_port_simple_hsr_join() and dsa_port_simple_hsr_leave(). These
functions monitor when two user ports of the same switch are part of the
same HSR device, and when that condition is true, they toggle the
NETIF_F_HW_HSR_DUP feature flag of both net devices.
Normally only dsa_port_simple_hsr_join() and dsa_port_simple_hsr_leave()
are needed. The dsa_port_simple_hsr_validate() helper is just to see
what kind of configuration could be offloadable using the generic
helpers. This is used by switch drivers which are not currently using
the right tagging protocol to offload this HSR ring, but could in
principle offload it after changing the tagger.

As discussed here:
https://lore.kernel.org/netdev/20240620090210.drop6jwh7e5qw556@skbuf/
the fact is that the xrs700x.c driver only supports offloading
HSR_PT_SLAVE_A and HSR_PT_SLAVE_B (which were the only port types at the
time the offload was written, _for this driver_).
Up until now, the API did not explicitly tell offloading drivers what
port has what role. So xrs700x can get confused and think that it can
support a configuration which it actually can't. There was a table in
the attached link which gave an example:
$ ip link add name hsr0 type hsr slave1 swp0 slave2 swp1 \
interlink swp2 supervision 45 version 1
HSR_PT_SLAVE_A HSR_PT_SLAVE_B HSR_PT_INTERLINK
----------------------------------------------------------------
user
space 0 1 2
requests
----------------------------------------------------------------
XRS700X
driver 1 2 -
understands
The switch would act as if the ring ports were swp1 and swp2.
Now that we have explicit hsr_get_port_type() API, let's use that to
work around the unintended semantical changes of the offloading API
brought by the introduction of interlink ports in HSR.

Since the introduction of HSR_PT_INTERLINK in commit 5055cccfc2d1 ("net:

types require different settings for hardware offload, which was not the
case before when we only had HSR_PT_SLAVE_A and HSR_PT_SLAVE_B. But
there is currently no way to know which port is which type, so create
the hsr_get_port_type() API function and export it.
When hsr_get_port_type() is called from the device driver, the port can
must be found in the HSR port list. An important use case is for this
function to work from offloading drivers' NETDEV_CHANGEUPPER handler,
which is triggered by hsr_portdev_setup() -> netdev_master_upper_dev_link().
Therefore, we need to move the addition of the hsr_port to the HSR port
list prior to calling hsr_portdev_setup(). This makes the error
restoration path also more similar to hsr_del_port(), where
kfree_rcu(port) is already used.

net: phy: phy-c45: add SQI and SQI+ support for OATC14 10Base-T1S PHYs
Add support for reading Signal Quality Indicator (SQI) and enhanced SQI+
from OATC14 10Base-T1S PHYs.
- Introduce MDIO register definitions for DCQ_SQI and DCQ_SQIPLUS.
- Add `genphy_c45_oatc14_get_sqi_max()` to return the maximum supported
SQI/SQI+ level.
- Add `genphy_c45_oatc14_get_sqi()` to return the current SQI or SQI+
value.
- Update `include/linux/phy.h` to expose the new APIs.
SQI+ capability is read from the Advanced Diagnostic Features Capability
register (ADFCAP). If SQI+ is supported, the driver calculates the value
from the MSBs of the DCQ_SQIPLUS register; otherwise, it falls back to
basic SQI (0-7 levels). This enables ethtool to report the SQI value for
OATC14 10Base-T1S PHYs.

net/mlx5e: Use standard unit definitions for bandwidth conversion
MLX5E_100MB and MLX5E_1GB defines are confusing, MLX5E_100MB is not
equal to 100 * MEGA, and MLX5E_1GB is not equal to one GIGA, as they
hide the Kbps rate conversion required for ieee_maxrate.
Replace hardcoded bandwidth conversion values with standard unit

MLX5E_100MB_TO_KB/MLX5E_1GB_TO_KB to clarify these are conversion

net: dsa: b53: fix ARL accesses for BCM5325/65 and allow VID 0
ARL entries on BCM5325 and BCM5365 were broken significantly in two
ways:
- Entries for the CPU port were using the wrong port id, pointing to a
non existing port.
- Setting the VLAN ID for entries was not done, adding them all to VLAN
0 instead.
While the former technically broke any communication to the CPU port,
with the latter they were added to the currently unused VID 0, so they
never became effective. Presumably the default PVID was set to 1 because
of these issues 0 was broken (and the root cause not found).
So fix writing and reading entries on BCM5325/65 by first fixing the CPU
port entries, then fixing setting the VLAN ID for entries.
Finally, re-allow VID 0 for BCM5325/65 to allow the whole 1-15 VLAN ID
range to be available to users, and align VLAN handling with all other
switch chips.

We currently use the mask 0xf for writing and reading b53_entry::port,
but this is only correct for unicast ARL entries. Multicast ARL entries
use a bitmask, and 0xf is not enough space for ports > 3, which includes
the CPU port.
So extend the mask accordingly to also fit port 4 (bit 4) and MII (bit
5). According to the datasheet the multicast port mask is [60:48],
making it 12 bit wide, but bits 60-55 are reserved anyway, and collide
with the priority field at [60:59], so I am not sure if this is valid.
Therefore leave it at the actual used range, [53:48].
The ARL search result register differs a bit, and there the mask is only
[52:48], so only spanning the user ports. The MII port bit is
contained in the Search Result Extension register. So create a separate
search result parse function that properly handles this.

net: pcs: lynx: accept in-band autoneg for 2500base-x
Testing in two circumstances:
1. back to back optical SFP+ connection between two LS1028A-QDS ports
with the SCH-26908 riser card
2. T1042 with on-board AQR115 PHY using "OCSGMII", as per
https://lore.kernel.org/lkml/aIuEvaSCIQdJWcZx@FUE-ALEWI-WINX/
strongly suggests that enabling in-band auto-negotiation is actually
possible when the lane baud rate is 3.125 Gbps.
It was previously thought that this would not be the case, because it
was only tested on 2500base-x links with on-board Aquantia PHYs, where
it was noticed that MII_LPA is always reported as zero, and it was
thought that this is because of the PCS.
Test case #1 above shows it is not, and the configured MII_ADVERTISE on
system A ends up in the MII_LPA on system B, when in 2500base-x mode
(IF_MODE=0).
Test case #2, which uses "SGMII" auto-negotiation (IF_MODE=3) for the
3.125 Gbps lane, is actually a misconfiguration, but it is what led to
the discovery.
There is actually an old bug in the Lynx PCS driver - it expects all
register values to contain their default out-of-reset values, as if the
PCS were initialized by the Reset Configuration Word (RCW) settings.
There are 2 cases in which this is problematic:
- if the bootloader (or previous kexec-enabled Linux) wrote a different
IF_MODE value
- if dynamically changing the SerDes protocol from 1000base-x to
2500base-x, e.g. by replacing the optical SFP module.
Specifically in test case #2, an accidental alignment between the
bootloader configuring the PCS to expect SGMII in-band code words, and
the AQR115 PHY actually transmitting SGMII in-band code words when
operating in the "OCSGMII" system interface protocol, led to the PCS
transmitting replicated symbols at 3.125 Gbps baud rate. This could only
have happened if the PCS saw and reacted to the SGMII code words in the
first place.
Since test #2 is invalid from a protocol perspective (there seems to be
no standard way of negotiating the data rate of 2500 Mbps with SGMII,
and the lower data rates should remain 10/100/1000), in-band auto-negotiation
for 2500base-x effectively means Clause 37 (i.e. IF_MODE=0).
Make 2500base-x be treated like 1000base-x in this regard, by removing
all prior limitations and calling lynx_pcs_config_giga().
This adds a new feature: LINK_INBAND_ENABLE and at the same time fixes
the Lynx PCS's long standing problem that the registers (specifically
IF_MODE, but others could be misconfigured as well) are not written by
the driver to the known valid values for 2500base-x.

But h5_link_control() only enqueues the packet and requires the caller
