Extend the Lantiq GSWIP device tree binding to also cover MaxLinear
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,

Currently the MII clk vs. data delay is configured based on the PHY
interface mode.
In addition to that add support for setting up MII delays using the
standard Device Tree properties 'tx-internal-delay-ps' and
'rx-internal-delay-ps', using the values determined by the PHY interface
mode as default to maintain backward compatibility with legacy device
trees.

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.

On standalone switch ICs the link parameters of the CPU port need to
be setup just like user ports. The destinction in the driver to not
carry out link parameter setup for the CPU port does make sense for
in-SoC switches on which the CPU port is internally connected to the
SoC's Ethernet MAC.
Set link parameters also for the CPU port unless it is an internal
interface. Note that the internal TP PHYs anyway cannot be used as
CPU ports, hence it doesn't matter that they are now also covered by
that condition.

net: bridge: fix two MST bugs
Patch 01 fixes a race condition that exists between expired fdb deletion
and port deletion when MST is enabled. Learning can happen after the
port's state has been changed to disabled which could lead to that
port's memory being used after it's been freed. The issue was reported
by syzbot, more information in patch 01. Patch 02 fixes an issue with
MST's static key which Ido spotted, we can have multiple bridges with MST
and a single bridge can erroneously disable it for all.

syzbot reported[1] a use-after-free when deleting an expired fdb. It is
due to a race condition between learning still happening and a port being
deleted, after all its fdbs have been flushed. The port's state has been
toggled to disabled so no learning should happen at that time, but if we
have MST enabled, it will bypass the port's state, that together with VLAN
filtering disabled can lead to fdb learning at a time when it shouldn't
happen while the port is being deleted. VLAN filtering must be disabled
because we flush the port VLANs when it's being deleted which will stop
learning. This fix adds a check for the port's vlan group which is
initialized to NULL when the port is getting deleted, that avoids the port
state bypass. When MST is enabled there would be a minimal new overhead
in the fast-path because the port's vlan group pointer is cache-hot.

Liang reported an issue where setting a slave’s actor_port_prio to
predefined values such as 0, 255, or 65535 would cause a system crash.
The problem occurs because in bond_opt_parse(), when the provided value
matches a predefined table entry, the function returns that table entry,
which does not contain slave information. Later, in
bond_option_actor_port_prio_set(), calling bond_slave_get_rtnl() leads
to a NULL pointer dereference.
Since actor_port_prio is defined as a u16 and initialized to the default
value of 255 in ad_initialize_port(), there is no need for the
bond_actor_port_prio_tbl. Using the BOND_OPTFLAG_RAWVAL flag is sufficient.

KSZ9477/KSZ9897 and LAN937X families of switches use a reserved multicast
address table for some specific forwarding with some multicast addresses,
like the one used in STP. The hardware assumes the host port is the last
port in KSZ9897 family and port 5 in LAN937X family. Most of the time
this assumption is correct but not in other cases like KSZ9477.
Originally the function just setups the first entry, but the others still
need update, especially for one common multicast address that is used by
PTP operation.
LAN937x also uses different register bits when accessing the reserved
table.

At present IDPF supports only 0x1452 and 0x145C as PF and VF device IDs
on our current generation hardware. Future hardware exposes a new set of
device IDs for each generation. To avoid adding a new device ID for each
generation and to make the driver forward and backward compatible,
make use of the IDPF PCI programming interface to load the driver.
Write and read the VF_ARQBAL mailbox register to find if the current
device is a PF or a VF.
PCI SIG allocated a new programming interface for the IDPF compliant
ethernet network controller devices. It can be found at:
https://members.pcisig.com/wg/PCI-SIG/document/20113

which supports the IDPF PCI programming interface.

net: stmmac: socfpga: Add Agilex5 platform support and enhancements
This patch series adds support for the Agilex5 EMAC platform to the
dwmac-socfpga driver.
The series includes:
- Platform configuration for Agilex5 EMAC
- Enabling Time-Based Scheduling (TBS) for Tx queues 6 and 7
- Enabling TCP Segmentation Offload(TSO)
- Adding hardware-supported cross timestamping using the SMTG IP,
allowing precise synchronization between MAC and system time via
PTP_SYS_OFFSET_PRECISE.
====================

Cross timestamping is supported on Agilex5 platform with Synchronized
Multidrop Timestamp Gathering(SMTG) IP. The hardware cross-timestamp
result is made available the applications through the ioctl call
PTP_SYS_OFFSET_PRECISE, which inturn calls stmmac_getcrosststamp().
Device time is stored in the MAC Auxiliary register. The 64-bit System
time (ARM_ARCH_COUNTER) is stored in SMTG IP. SMTG IP is an MDIO device
with 0xC - 0xF MDIO register space holds 64-bit system time.
This commit is similar to following commit for Intel platforms:

Agilex5 HPS EMAC uses the dwxgmac-3.10a IP, unlike previous socfpga
platforms which use dwmac1000 IP. Due to differences in platform
configuration, Agilex5 requires a distinct setup.
Introduce a setup_plat_dat() callback in socfpga_dwmac_ops to handle
platform-specific setup. This callback is invoked before
stmmac_dvr_probe() to ensure the platform data is correctly
configured. Also, implemented separate setup_plat_dat() callback for
current socfpga platforms and Agilex5.

The driver calls mfd_add_devices() but fails to call mfd_remove_devices()
in error paths after successful MFD device registration and in the remove

Replace mfd_add_devices with devm_mfd_add_devices to automatically
manage the device resources.

net/mlx5e: SHAMPO fixes for 64KB page size
This series by Dragos contains fixes for HW-GRO issues found on systems

====================

The MLX5E_SHAMPO_WQ_HEADER_PER_PAGE and
MLX5E_SHAMPO_LOG_MAX_HEADER_ENTRY_SIZE macros are used directly in
several places under the assumption that there will always be more
headers per WQE than headers per page. However, this assumption doesn't
hold for 64K page sizes and higher MTUs (> 4K). This can be first
observed during header page allocation: ksm_entries will become 0 during
alignment to MLX5E_SHAMPO_WQ_HEADER_PER_PAGE.
This patch introduces 2 additional members to the mlx5e_shampo_hd struct
which are meant to be used instead of the macrose mentioned above.
When the number of headers per WQE goes below
MLX5E_SHAMPO_WQ_HEADER_PER_PAGE, clamp the number of headers per
page and expand the header size accordingly so that the headers
for one WQE cover a full page.
All the formulas are adapted to use these two new members.

mlx5e_hw_gro_skb_has_enough_space() uses a formula to check if there is
enough space in the skb frags to store more data. This formula is
incorrect for 64K page sizes and it triggers early GRO session
termination because the first fragment will blow up beyond
GRO_LEGACY_MAX_SIZE.
This patch adds a special case for page sizes >= GRO_LEGACY_MAX_SIZE
(64K) which uses the skb->len instead. Within this context,
the check is safe from fragment overflow because the hardware
will continuously fill the data up to the reservation size of 64K
and the driver will coalesce all data from the same page to the same
fragment. This means that the data will span one fragment or at most
two for such a large page size.
It is expected that the if statement will be optimized out as the
check is done with constants.

HW-GRO is broken on mlx5 for 64K page sizes. The patch in the fixes tag
didn't take into account larger page sizes when doing an align down
of max_ksm_entries. For 64K page size, max_ksm_entries is 0 which will skip
mapping header pages via WQE UMR. This breaks header-data split
and will result in the following syndrome:
mlx5_core 0000:00:08.0 eth2: Error cqe on cqn 0x4c9, ci 0x0, qn 0x1133, opcode 0xe, syndrome 0x4, vendor syndrome 0x32

mlx5_core 0000:00:08.0 eth2: ERR CQE on RQ: 0x1133
Furthermore, the function that fills in WQE UMRs for the headers
(mlx5e_build_shampo_hd_umr()) only supports mapping page sizes that
fit in a single UMR WQE.
This patch goes back to the old non-aligned max_ksm_entries value and it
changes mlx5e_build_shampo_hd_umr() to support mapping a large page over
multiple UMR WQEs.
This means that mlx5e_build_shampo_hd_umr() can now leave a page only
partially mapped. The caller, mlx5e_alloc_rx_hd_mpwqe(), ensures that
there are enough UMR WQEs to cover complete pages by working on
ksm_entries that are multiples of MLX5E_SHAMPO_WQ_HEADER_PER_PAGE.

The ICSSG driver does the initial FDB configuration which
includes setting the control registers. Other run time
management like learning is managed by the PRU's. The default
FDB hash size used by the firmware is 512 slots, which is
currently missing in the current driver. Update the driver
FDB config to include FDB hash size as well.
Please refer trm [1] 6.4.14.12.17 section on how the FDB config
register gets configured. From the table 6-1404, there is a reset
field for FDB_HAS_SIZE which is 4, meaning 1024 slots. Currently
the driver is not updating this reset value from 4(1024 slots) to
3(512 slots). This patch fixes this by updating the reset value
to 512 slots.

One GRO-cell device's NAPI callback can nest into the GRO-cell of
another device if the underlying device is also using GRO-cell.
This is the case for IPsec over vxlan.
These two GRO-cells are separate devices. From lockdep's point of view
it is the same because each device is sharing the same lock class and so
it reports a possible deadlock assuming one device is nesting into
itself.
Hold the bh_lock only while accessing gro_cell::napi_skbs in
gro_cell_poll(). This reduces the locking scope and avoids acquiring the
same lock class multiple times.

Add support for Factory Test TLV commands
ath11k:
Add support for Tx Power insertion
ath12k:
Add support for BSS color change
And of course there is the usual set of cleanups and bug fixes across
the entire family of "ath" drivers.
We do expect to have one more pull request before the v6.19 merge
window to pull in the refactored ath12k driver from the ath12k-ng
branch.
