Now that the differences in ARL entry formats are neatly contained into
functions per chip family, wrap them into an ops struct and add wrapper
functions to access them.

When converting the Renesas network drivers to use flags from enum
hwtstamp_rx_filters to control when to timestamp packages instead of a
driver specific schema with bit-wise flags an error was made.
The bit-wise driver specific flags correct logic to set get_ts was:
q: RAVB_BE + tstamp_rx_ctrl: 0 => 0
q: RAVB_NC + tstamp_rx_ctrl: 0 => 0
q: RAVB_BE + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_V2_L2_EVENT => 0
q: RAVB_NC + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_V2_L2_EVENT => 1
q: RAVB_BE + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_ALL => 1
q: RAVB_NC + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_ALL => 1
The converted logic to use enum flags mapped tstamp_rx_ctrl as
0 to HWTSTAMP_FILTER_NONE
RAVB_RXTSTAMP_TYPE_V2_L2_EVENT to HWTSTAMP_FILTER_PTP_V2_L2_EVENT
RAVB_RXTSTAMP_TYPE_ALL to HWTSTAMP_FILTER_ALL
But the logic was incorrectly changed to:
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_NONE => 1 (error)
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_NONE => 0
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_PTP_V2_L2_EVENT => 0
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_PTP_V2_L2_EVENT => 1
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_ALL => 1
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_ALL => 0 (error)
This change restores the converted flag check to the correct logic of
the bit-wise driver specific flags.

Add mlx5_fs_set_root_dev() function which swaps the root namespace
core device with another one for a given table_type.
It is intended for usage only by RDMA_TRANSPORT tables in case of LAG
configuration, to allow the creation of tables during LAG always
through the LAG master device, which is valid since during LAG the
master is allowed to manage the RDMA_TRANSPORT tables of its slaves.
In addition move the table_type enum to global include to allow its use
in a downstream patch in the RDMA driver.

Intel Wired LAN Driver Updates 2025-11-06 (i40, ice, iavf)
Mohammad Heib introduces a new devlink parameter, max_mac_per_vf, for
controlling the maximum number of MAC address filters allowed by a VF. This
allows administrators to control the VF behavior in a more nuanced manner.
Aleksandr and Przemek add support for Receive Side Scaling of GTP to iAVF
for VFs running on E800 series ice hardware. This improves performance and
scalability for virtualized network functions in 5G and LTE deployments.

The lan8814 is a quad-phy and it is using QSGMII towards the MAC.
The problem is that everytime when one of the ports is configured then
the PCS is reseted for all the PHYs. Meaning that the other ports can
loose traffic until the link is establish again.
To fix this, do the reset one time for the entire PHY package.

Once the netshaper is created for MANA, the current bandwidth
is reported in debugfs like this:
$ sudo ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/net_shaper.yaml \
--do set \
--json '{"ifindex":'3',
"handle":{ "scope": "netdev", "id":'1' },
"bw-max": 200000000 }'
None
$ sudo cat /sys/kernel/debug/mana/1/vport0/current_speed
200
After the shaper is deleted, it is expected to report
the maximum speed supported by the SKU. But currently it is
reporting 0, which is incorrect.
Fix this inconsistency, by resetting apc->speed to apc->max_speed
during deletion of the shaper object. This will improve
readability and debuggability.

EN7581 and AN7583 SoCs are capable of DMA mapping non-linear tx skbs on
non-consecutive DMA descriptors. This feature is useful when multiple
flows are queued on the same hw tx queue since it allows to fully utilize
the available tx DMA descriptors and to avoid the starvation of
high-priority flow we have in the current codebase due to head-of-line
blocking introduced by low-priority flows.

as the translating code can be removed while at the same time making it
clear the flags are not flags written to hardware registers.

The struct rcar_gen4_ptp_private provides two fields for convenience of
its users, tstamp_tx_ctrl and tstamp_rx_ctrl. These fields are not used
by the rcar_gen4_ptp driver itself but only by the drivers using it.
Upcoming work will enable the RAVB driver currently only supporting gPTP
on pre-Gen4 SoCs to use the Gen4 implementation as well. To facilitate
this the convenience of having these fields in struct
rcar_gen4_ptp_private becomes a problem as the RAVB driver already have
it's own driver specific fields for the same thing.
Move the fields from struct rcar_gen4_ptp_private to each driver using
the Gen4 gPTP clocks own private data structures. There is no functional
change.

simplifying .get_rxnfc.
Remove the handling of GRXRINGS in .get_rxnfc() by moving it to the new
.get_rx_ring_count().
Given that tg3_get_rxnfc() only handles ETHTOOL_GRXRINGS, then this
function becomes useless now, and it is removed.
This also fixes the behavior for devices without MSIX support.
Previously, the function would return -EOPNOTSUPP, but now it correctly
returns 1.
The functionality remains the same: return the current queue count
if the device is running, otherwise return the minimum of online
CPUs and TG3_RSS_MAX_NUM_QS.

Extend the iavf driver to support Receive Side Scaling (RSS)
configuration for GTP (GPRS Tunneling Protocol) flows using ethtool.
The implementation introduces new RSS flow segment headers and hash field
definitions for various GTP encapsulations, including:
- GTPC
- GTPU (IP, Extension Header, Uplink, Downlink)
- TEID-based hashing
The ethtool interface is updated to parse and apply these new flow types
and hash fields, enabling fine-grained traffic distribution for GTP-based
mobile workloads.
This enhancement improves performance and scalability for virtualized
network functions (VNFs) and user plane functions (UPFs) in 5G and LTE
deployments.

Consolidate updates to the Protocol Type (PTYPE) bitmap definitions
across multiple flow types in the Intel ICE driver to support GTP
(GPRS Tunneling Protocol) encapsulated traffic.
Enable improved Receive Side Scaling (RSS) configuration for both user
and control plane GTP flows.
Cover a wide range of protocol and encapsulation scenarios, including:
- MAC OFOS and IL
- IPv4 and IPv6 (OFOS, IL, ALL, no-L4)
- TCP, SCTP, ICMP
- GRE OF
- GTPC (control plane)
Expand the PTYPE bitmap entries to improve classification and
distribution of GTP traffic across multiple queues, enhancing
performance and scalability in mobile network environments.

This commit implements the core RSS context management and configuration
logic for GTP (GTPU) protocol support in VF RSS operations.
Key implementation features:
- GTPU hash context management with pre/post processing functions
- Context index calculation and mapping for different GTPU scenarios
- Integration with main RSS configuration flow via wrapper functions
- Support for IPv4/IPv6 GTPU RSS configurations
- Rollback mechanism for handling RSS rule conflicts
- Hash context reset and cleanup functionality
The implementation provides comprehensive GTPU RSS support by:
1. Adding ice_add_rss_cfg_pre_gtpu() for preprocessing GTPU contexts
2. Adding ice_add_rss_cfg_post_gtpu() for postprocessing configurations
3. Adding ice_calc_gtpu_ctx_idx() for context index calculation
4. Integrating GTPU logic into ice_add_rss_cfg_wrap() and
ice_rem_rss_cfg_wrap()
5. Supporting context tracking in VF hash_ctx structures
This completes the GTP RSS infrastructure enabling VFs to configure
RSS hashing on GTP-encapsulated traffic.

Add driver for the MaxLinear GSW1xx family of Ethernet switch ICs which
are based on the same IP as the Lantiq/Intel GSWIP found in the Lantiq VR9
and Intel GRX MIPS router SoCs. The main difference is that instead of
using memory-mapped I/O to communicate with the host CPU these ICs are
connected via MDIO (or SPI, which isn't supported by this driver).
Implement the regmap API to access the switch registers over MDIO to allow
reusing lantiq_gswip_common for all core functionality.
The GSW1xx also comes with a SerDes port capable of 1000Base-X, SGMII and
2500Base-X, which can either be used to connect an external PHY or SFP
cage, or as the CPU port. Support for the SerDes interface is implemented
in this driver using the phylink_pcs interface.

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.

When adding FDB entries to the MAC bridge table on GSWIP 2.2 or later it
is needed to set an (undocumented) bit to mark the entry as valid. If this
bit isn't set for entries in the MAC bridge table, then those entries won't
be considered as valid MAC addresses.

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.
