AN8811HB needs a MCU soft-reset cycle before firmware loading begins.
Assert the MCU (hold it in reset) and immediately deassert (release)
via a dedicated PBUS register pair (0x5cf9f8 / 0x5cf9fc), accessed
through a registered mdio_device at PHY-addr+8.
Add __air_pbus_reg_write() as a low-level helper taking a struct
mdio_device *, create and register the PBUS mdio_device in
an8811hb_probe() and store it in priv->pbusdev, then implement
an8811hb_mcu_assert() / _deassert() on top of it. Add
an8811hb_remove() to unregister the PBUS device on teardown. Wire
both calls into an8811hb_load_firmware() and en8811h_restart_mcu()
so every firmware load or MCU restart on AN8811HB correctly sequences
the reset control registers.

phy_advertise_eee_all() copies supported_eee into advertising_eee
unconditionally, overwriting any filtering applied during phy_probe()
based on DT eee-broken-* properties or driver-populated
eee_disabled_modes. genphy_c45_ethtool_set_eee() calls this helper
when user space passes an empty advertisement, undoing the filtering.
Apply the same eee_disabled_modes mask in phy_advertise_eee_all() so
the filtering survives the copy, matching the pattern in phy_probe()
and phy_support_eee().

phy_support_eee() copies supported_eee into advertising_eee
unconditionally, overwriting any filtering applied during phy_probe()
based on DT eee-broken-* properties or driver-populated
eee_disabled_modes. MAC drivers that call phy_support_eee() after
probe (e.g. bcmgenet, fec, lan743x, lan78xx, r8169) then cause the PHY
to advertise EEE for modes the user marked as broken.
The symptom is that ethtool --show-eee on the local interface reports
"not supported" (supported & ~eee_disabled_modes is empty) while the
link partner sees EEE negotiated and active.
phy_probe() already filters advertising_eee via eee_disabled_modes
after calling of_set_phy_eee_broken(). Apply the same mask in
phy_support_eee() so the filtering survives the copy.

genphy_c45_an_config_eee_aneg() writes the EEE advertisement to the
auto-negotiation device's MMD register space (MDIO_MMD_AN, register
MDIO_AN_EEE_ADV). These registers are read by the link partner only
during auto-negotiation, so writing them while autoneg is disabled
cannot influence the link. On some PHYs (e.g. Broadcom BCM54213PE)
the write nevertheless reaches the chip and disturbs the receive
datapath.
Concretely, running
ethtool -s eth0 speed 100 duplex full autoneg off
ethtool --set-eee eth0 eee off
leaves eth0 with TX working and RX completely silent on a
Raspberry Pi 4 / CM4 board (bcmgenet + BCM54213PE in rgmii-rxid).
Switching back to autoneg recovers the link.
Prior to commit f26a29a038ee ("net: phy: ensure that genphy_c45_an_config_eee_aneg() sees new value of phydev->eee_cfg.eee_enabled"),
the disable path was effectively a no-op because the helper read
the stale eee_cfg.eee_enabled, so the underlying PHY behavior never
surfaced.
Bisected on rpi-6.12.y between commits 83943264 (good) and
effcbc88 (bad) to f26a29a038ee.

LAN8814 QSGMII soft reset was moved into the probe function to avoid
triggering it for each of 4 PHY-s in the package.
However, that broke QSGMII link between the MAC and PHY on most LAN8814
PHY-s, specificaly for us on the Microchip LAN969x switch.
Reading the QSGMII status registers it was visible that lanes were only
partially synced.
It looks like the reset timing is crucial, so lets move the reset back
into the .config_init function but guard it with phy_package_init_once()
to avoid it being triggered on each of 4 PHY-s in the package.
Change the probe function to use phy_package_probe_once() for coma and PtP
setup.

to HW queues for zero-copy operations and AF_XDP
- Number of code moves to help the compiler with inlining. Avoid
output arguments for returning drop reason where possible
- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints

As noted in the blamed commit, the AR8035 and other PHYs from this
family advertise the Extended Next Page support by default, which may be
understood by some partners as this PHY being multi-gig capable.
The fix is to disable XNP advertising, which is done by setting bit 12
of the Auto-Negotiation Advertisement Register (MII_ADVERTISE).
The blamed commit incorrectly uses MDIO_AN_CTRL1_XNP, which is bit 13 as per
802.3 : 45.2.7.1 AN control register (Register 7.0)
BIT 12 in MII_ADVERTISE is wrapped by ADVERTISE_RESV, used by some
drivers such as the aquantia one. 802.3 Clause 28 defines bit 12 as
Extended Next Page ability, at least in recent versions of the standard.
Let's add a define for it and use it in the at803x driver.

MDIO bus controllers are not required to wait for write transactions to
complete before returning as synchronization is often achieved by polling
status bits.
This can cause issues when disabling interrupts since an interrupt could
fire before the interrupt handler is unregistered and there's no status
bit to poll.
Add a phy_write_barrier() function and use it in phy_disable_interrupts()
to fix this issue. The write barrier just reads an MII register and
discards the value, which is enough to guarantee that previous writes have
completed.

Some PHYs (e.g. Broadcom BCM54xx, Realtek RTL8211F) implement
autonomous EEE where the PHY manages LPI signaling without forwarding
it to the MAC. This conflicts with MAC drivers that implement their own
LPI control.
Add a .disable_autonomous_eee callback to struct phy_driver and call it
from phy_support_eee(). When a MAC driver indicates it supports EEE via
phy_support_eee(), the PHY's autonomous EEE is automatically disabled so
the MAC can manage LPI entry/exit.

Add support for spread spectrum clocking (SSC) on RTL8211F(D)(I)-CG,
RTL8211FS(I)(-VS)-CG, RTL8211FG(I)(-VS)-CG PHYs. The implementation
follows EMI improvement application note Rev. 1.2 for these PHYs.
The current implementation enables SSC for both RXC and SYSCLK clock
signals. Introduce DT properties 'realtek,clkout-ssc-enable',
'realtek,rxc-ssc-enable' and 'realtek,sysclk-ssc-enable' which control
CLKOUT, RXC and SYSCLK SSC spread spectrum clocking enablement on these
signals.

Several GPON ONT SFP sticks based on Realtek RTL960x report
1000BASE-LX at 1300MBd in their EEPROM but can operate at 2500base-X.
On hosts capable of 2500base-X (e.g. Banana Pi R3 / MT7986), the
kernel negotiates only 1G because it trusts the incorrect EEPROM data.
Add quirks for:
- Hisense-Leox LXT-010S-H
- Hisense ZNID-GPON-2311NA
- HSGQ HSGQ-XPON-Stick
Each quirk advertises 2500base-X and ignores TX_FAULT during the
module's ~40s Linux boot time.
Tested on Banana Pi R3 (MT7986) with OpenWrt 25.12.1, confirmed
2.5Gbps link and full throughput with flow offloading.

Enable auto-downshift from 1000BASE-T to 100BASE-TX after 2 failed
auto-negotiation attempts by default. This ensures that links with
faulty or missing cable pairs (C and D) fall back to 100Mbps without
requiring userspace configuration.
The downshift count is stored in the driver's private data and applied
in config_init, so user changes via ethtool are preserved across
suspend/resume cycles.
Users can override or disable downshift at runtime:
ethtool --set-phy-tunable eth0 downshift off

PHY. This allows runtime configuration of the auto-downshift feature
via ethtool:
ethtool --set-phy-tunable eth0 downshift on count 3
The LAN88xx PHY supports downshifting from 1000BASE-T to 100BASE-TX
after 2-5 failed auto-negotiation attempts. Valid count values are
2, 3, 4 and 5.
This is based on an earlier downstream implementation by Phil Elwell.

Expose LED1 and LED2 pins via the PHY LED framework. Each pin has a
source mask (MASK_LOW + MASK_EXT registers) selecting which hardware
events light it, plus a CTL field in the shared 0xA83B register
(RMW; LED4 is firmware-controlled per the datasheet).
Hardware can offload per-speed link triggers (1000/2500/5000/10000),
RX/TX activity, and force-on. LINK_100 is accepted only alongside
LINK_1000: source bit 4 lights at both speeds and 100-alone isn't
representable, so the unrepresentable case falls to software.
The chip has five LED pins; only LED1/LED2 are exposed here as those
are the only ones characterized on tested hardware. LED4 is firmware-
controlled regardless of strap configuration.
Tested on TRENDnet TEG-S750 (LED1/LED2 wired to an antiparallel
bicolor LED): brightness_set via sysfs; netdev trigger offloaded=1
with amber lit at 100M/1G/2.5G and green lit at 10G via respective

The BCM84891 and BCM84892 are 10GBASE-T PHYs in the same family as the
BCM84881, sharing the register map and most callbacks. They add USXGMII
as a host interface mode.
bcm8489x_config_init() is separate from bcm84881_config_init(): it
allows only USXGMII (the only host mode available on the tested
hardware) and clears MDIO_CTRL1_LPOWER, which is set at boot on the
tested platform. Does not recur on ifdown/ifup, cable events, or
link-partner advertisement changes, so config_init is sufficient.
For USXGMII, read_status() skips the 0x4011 host-mode register: it
returns the same value regardless of negotiated copper speed (USXGMII
symbol replication). Speed comes from phy_resolve_aneg_linkmode() via
standard C45 AN resolution.
Tested on TRENDnet TEG-S750 (RTL9303 + 1x BCM84891 + 4x BCM84892)
running OpenWrt, where the MDIO controller driver is currently
OpenWrt-specific. Link verified at 100M, 1G, 2.5G, 10G.

This is a 2.5G copper module which appears to be based on a Motorcomm
YT8821 PHY. There doesn't seem to be a usable way to to access the PHY
(I2C address 0x56 provides only read-only C22 access, and Rollball is
also not working).
The module does not report the correct extended compliance code for
2.5GBase-T, and instead claims to support SONET OC-48 and Fibre Channel:
Identifier : 0x03 (SFP)
Extended identifier : 0x04 (GBIC/SFP defined by 2-wire interface ID)
Connector : 0x07 (LC)
Transceiver codes : 0x00 0x01 0x00 0x00 0x40 0x40 0x04 0x00 0x00
Transceiver type : FC: Multimode, 50um (M5)
Encoding : 0x05 (SONET Scrambled)
BR Nominal : 2500MBd
Despite this, the kernel still enables the correct 2500Base-X interface
mode. However, for the module to actually work, it is also necessary to
disable inband auto-negotiation.
Enable the existing "sfp_quirk_oem_2_5g" for this module, which handles
that and also sets the bit for 2500Base-T link mode.

In commit 8110633db49d7de2 ("net: sfp-bus: allow SFP quirks to override
Autoneg and pause bits") we moved the setting of Autoneg and pause bits
before the call to SFP quirk when parsing SFP module support.
Since the quirk for Ubiquiti U-Fiber Instant SFP module zeroes the
support bits and sets 1000baseX_Full only, the above mentioned commit
changed the overall computed support from
1000baseX_Full, Autoneg, Pause, Asym_Pause
to just
1000baseX_Full.
This broke the SFP module for mvneta, which requires Autoneg for
1000baseX since commit c762b7fac1b249a9 ("net: mvneta: deny disabling
autoneg for 802.3z modes").
Fix this by setting back the Autoneg, Pause and Asym_Pause bits in the
quirk.

In various places in the kernel, we modify the fwnode "flags" member
by doing either:
fwnode->flags |= SOME_FLAG;
fwnode->flags &= ~SOME_FLAG;
This type of modification is not thread-safe. If two threads are both
mucking with the flags at the same time then one can clobber the
other.
While flags are often modified while under the "fwnode_link_lock",
this is not universally true.
Create some accessor functions for setting, clearing, and testing the
FWNODE flags and move all users to these accessor functions. New
accessor functions use set_bit() and clear_bit(), which are
thread-safe.

The RTL8224 has a register to configure the polarity of every pair of
each port. It provides device designers more flexbility when wiring the
chip.
Unfortunately, the register is left in an unknown state after a reset.
Thus on devices where the bootloader don't initialize it, the driver has
to do it to detect and use a link.
The MDI polarity swap can be set in the device tree using the property
enet-phy-pair-polarity. The u32 value is a bitfield where bit[0..3]
control the polarity of pairs A..D.

The RTL8224 has a register to configure a pair swap (from ABCD order to
DCBA) providing PCB designers more flexbility when wiring the chip. The
swap parameter has to be set correctly for each of the 4 ports before
the chip can detect a link.
After a reset, this register is (unfortunately) left in a random state,
thus it has to be initialized. On most of the devices the bootloader
does it once for all and we can rely on the value set, on some other it
is not and the kernel has to do it.
The MDI pair swap can be set in the device tree using the property
enet-phy-pair-order. The property is set to 0 to keep the default order
(ABCD), or 1 to reverse the pairs (DCBA).
