net: stmmac: remove unnecessary of_get_phy_mode() calls
This series removes unnecessary of_get_phy_mode() calls from the stmmac
glue drivers. stmmac_probe_config_dt() / devm_stmmac_probe_config_dt()
already gets the interface mode using device_get_phy_mode() and stores
it in plat_dat->phy_interface.
Therefore, glue drivers using of_get_phy_mode() are just duplicating
the work that has already been done.
This series adjusts the glue drivers to remove their usage of
of_get_phy_mode().

sun8i was using of_get_phy_mode() to set plat_dat->mac_interface, which
defaults to plat_dat->phy_interface when the mac-mode DT property is
not present. As nothing in arch/*/boot/dts sets the mac-mode property,
it is highly likely that these two will be identical, and thus there
is no need for this glue driver to set plat_dat->mac_interface.

tcp_in_quickack_mode() is called from input path for small packets.
It calls __sk_dst_get() which reads sk->sk_dst_cache which has been
put in sock_read_tx group (for good reasons).
Then dst_metric(dst, RTAX_QUICKACK) also needs extra cache line misses.
Cache RTAX_QUICKACK in icsk->icsk_ack.dst_quick_ack to no longer pull
these cache lines for the cases a delayed ACK is scheduled.
After this patch TCP receive path does not longer access sock_read_tx
group.

====================
udp_tunnel: GRO optimizations
The UDP tunnel GRO stage is source of measurable overhead for workload
based on UDP-encapsulated traffic: each incoming packets requires a full
UDP socket lookup and an indirect call.
In the most common setups a single UDP tunnel device is used. In such
case we can optimize both the lookup and the indirect call.
Patch 1 tracks per netns the active UDP tunnels and replaces the socket
lookup with a single destination port comparison when possible.
Patch 2 tracks the different types of UDP tunnels and replaces the
indirect call with a static one when there is a single UDP tunnel type
active.
I measure ~5% performance improvement in TCP over UDP tunnel stream
tests on top of this series.

It's quite common to have a single UDP tunnel type active in the
whole system. In such a case we can replace the indirect call for
the UDP tunnel GRO callback with a static call.
Add the related accounting in the control path and switch to static
call when possible. To keep the code simple use a static array for
the registered tunnel types, and size such array based on the kernel
config.

Most UDP tunnels bind a socket to a local port, with ANY address, no
peer and no interface index specified.
Additionally it's quite common to have a single tunnel device per
namespace.
Track in each namespace the UDP tunnel socket respecting the above.
When only a single one is present, store a reference in the netns.
When such reference is not NULL, UDP tunnel GRO lookup just need to
match the incoming packet destination port vs the socket local port.
The tunnel socket never sets the reuse[port] flag[s]. When bound to no
address and interface, no other socket can exist in the same netns
matching the specified local port.
Matching packets with non-local destination addresses will be
aggregated, and eventually segmented as needed - no behavior changes
intended.
Note that the UDP tunnel socket reference is stored into struct
netns_ipv4 for both IPv4 and IPv6 tunnels. That is intentional to keep
all the fastpath-related netns fields in the same struct and allow
cacheline-based optimization. Currently both the IPv4 and IPv6 socket
pointer share the same cacheline as the `udp_table` field.

Implement `mlx5_esw_qos_node_update_parent()` and

node reassignment.
Don't allow reassignment of nodes with active rate objects.
Update `esw_qos_node_set_parent()` to handle cases where
the parent is NULL. A NULL parent indicates that the scheduling element
is attached to the root scheduling element, and since only rate nodes
can be connected to the root, this update is now necessary.

Intel Wired LAN Driver Updates 2025-03-10 (ice, ixgbe)
For ice:
Paul adds generic checksum support for E830 devices.
Karol refactors PTP code related to E825C; simplifying PHY register info
struct, utilizing GENMASK, removing unused defines, etc.
For ixgbe:
Piotr adds PTP support for E610 devices.
Jedrzej adds reporting when overheating is detected on E610 devices.
The following are changes since commit 8ef890df4031121a94407c84659125cbccd3fdbe:
net: move misc netdev_lock flavors to a separate header
and are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE

E610 NICs unlike the previous devices utilising ixgbe driver
are notified in the case of overheating by the FW ACI event.
In event of overheat when threshold is exceeded, FW suspends all
traffic and sends overtemp event to the driver. Then driver
logs appropriate message and disables the adapter instance.
The card remains in that state until the platform is rebooted.
This approach is a solution to the fact current version of the
E610 FW doesn't support reading thermal sensor data by the
SW. So give to user at least any info that overtemp event
has occurred, without interface disappearing from the OS
without any note.

Minor PTP register refactor, including logical grouping E825C 1-step
timestamping registers. Remove unused register definitions
(PHY_REG_GPCS_BITSLIP, PHY_REG_REVISION).
Also, apply preferred GENMASK macro (instead of ICE_M) for register
fields definition affected by this patch.

E830 supports raw receive and generic transmit checksum offloads.
Raw receive checksum support is provided by hardware calculating the
checksum over the whole packet, regardless of type. The calculated
checksum is provided to driver in the Rx flex descriptor. Then the driver
assigns the checksum to skb->csum and sets skb->ip_summed to
CHECKSUM_COMPLETE.
Generic transmit checksum support is provided by hardware calculating the
checksum given two offsets: the start offset to begin checksum calculation,
and the offset to insert the calculated checksum in the packet. Support is
advertised to the stack using NETIF_F_HW_CSUM feature.
E830 has the following limitations when both generic transmit checksum
offload and TCP Segmentation Offload (TSO) are enabled:
1. Inner packet header modification is not supported. This restriction
includes the inability to alter TCP flags, such as the push flag. As a
result, this limitation can impact the receiver's ability to coalesce
packets, potentially degrading network throughput.
2. The Maximum Segment Size (MSS) is limited to 1023 bytes, which prevents
support of Maximum Transmission Unit (MTU) greater than 1063 bytes.
Therefore NETIF_F_HW_CSUM and NETIF_F_ALL_TSO features are mutually
exclusive. NETIF_F_HW_CSUM hardware feature support is indicated but is not
enabled by default. Instead, IP checksums and NETIF_F_ALL_TSO are the
defaults. Enforcement of mutual exclusivity of NETIF_F_HW_CSUM and
NETIF_F_ALL_TSO is done in ice_set_features(). Mutual exclusivity
of IP checksums and NETIF_F_HW_CSUM is handled by netdev_fix_features().
When NETIF_F_HW_CSUM is requested the provided skb->csum_start and
skb->csum_offset are passed to hardware in the Tx context descriptor
generic checksum (GCS) parameters. Hardware calculates the 1's complement
from skb->csum_start to the end of the packet, and inserts the result in
the packet at skb->csum_offset.

====================
net: phy: Rework linkmodes handling in a dedicated file
This is V5 of the phy_caps series. In a nutshell, this series reworks the way
we maintain the list of speed/duplex capablities for each linkmode so that we
no longer have multiple definition of these associations.
That will help making sure that when people add new linkmodes in
include/uapi/linux/ethtool.h, they don't have to update phylib and phylink as
well, making the process more straightforward and less error-prone.
It also generalises the phy_caps interface to be able to lookup linkmodes
from phy_interface_t, which is needed for the multi-port work I've been working
on for a while.
This V5 addresse Russell's and Paolo's reviews, namely :
- Error out when encountering an unknown SPEED_XXX setting
It prints an error and fails to initialize phylib. I've tested by
introducing a dummy 1.6T speed, I guess it's only a matter of time
before that actually happens :)
- Deal more gracefully with the fixed-link settings, keeping some level of
compatibility with what we had before by making sure we report a
single BaseT mode like before.

Phylink has internal code to get the MAC capabilities of a given PHY
interface (what are the supported speed and duplex).
Extract that into phy_caps, but use the link_capa for conversion. Add an
internal phylink helper for the link caps -> mac caps conversion, and
use this in phylink_caps_to_linkmodes().

phylink_caps_to_linkmodes() is used to derive a list of linkmodes that
can be conceivably exposed using a given set of speeds and duplex
through phylink's MAC capabilities.
This list can be derived from the link_caps array in phy_caps, provided
we convert the MAC capabilities into a LINK_CAPA bitmask first.
Introduce an internal phylink helper phylink_caps_to_link_caps() to
convert from MAC capabilities into phy_caps, then phy_caps_linkmodes()
to do the link_caps -> linkmodes conversion.
This avoids having to update phylink for every new linkmode.

phylink allows MAC drivers to report the capabilities in terms of speed,
duplex and pause support. This is done through a dedicated set of enum
values in the form of the MAC_ capabilities. They are very close to what
the LINK_CAPA_xxx can express, with the difference that LINK_CAPA don't
have any information about Pause/Asym Pause support.
To prepare converting phylink to using the phy_caps, add the mapping
between MAC capabilities and phy_caps. While doing so, we move the
phylink_caps_params array up a bit to simplify future commits.

When phylink creates a fixed-link configuration, it finds a matching
linkmode to set as the advertised, lp_advertising and supported modes
based on the speed and duplex of the fixed link.
Use the newly introduced phy_caps_lookup to get these modes instead of
phy_lookup_settings(). This has the side effect that the matched
settings and configured linkmodes may now contain several linkmodes (the
intersection of supported linkmodes from the phylink settings and the
linkmodes that match speed/duplex) instead of the one from
phy_lookup_settings().

When configuring PHY advertising with autoneg disabled, we lookd for an
exact linkmode to advertise and configure for the requested Speed and
Duplex, specially at or over 1G.
Using phy_caps_lookup allows us to build a list of the supported
linkmodes at that speed that we can advertise instead of the first mode
that matches.
