Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.

Core & protocols:

- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT

- Use flex array for netdevice priv area, ensure its cache alignment

- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful

- Support scheduling transmission of packets based on CLOCK_TAI

- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets

- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address

- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync

- Improve TCP compliance with RFC 9293 for simultaneous connect()

- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it

- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled

- Introduce IPPROTO_SMC for selecting SMC when socket is created

- Allow UDP GSO transmit from devices with no checksum offload

- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding

- nf_tables: shrink memory consumption for transaction objects

Things we sprinkled into general kernel code:

- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]

- Add IRQ information in sysfs for auxiliary bus

- Introduce guard definition for local_lock

- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures

BPF:

- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered

- Add new kfuncs for a generic, open-coded bits iterator

- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head

- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules

- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs

- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter

- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs

Driver API:

- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose

- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits

- Track additional RSS contexts in the core, make sure configuration
changes don't break them

- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths

- Support updating firmware on SFP modules

Tests and tooling:

- mptcp: use net/lib.sh to manage netns

- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints

- openvswitch: make test self-contained (don't depend on OvS CLI
tools)

net: ti: icssg-prueth: Split out common object into module

icssg_prueth.c and icssg_prueth_sr1.c drivers use multiple common .c
files. These common objects are getting added to multiple modules. As a
result when both drivers are enabled in .config, below warning is seen.

drivers/net/ethernet/ti/Makefile: icssg/icssg_common.o is added to multiple modules: icssg-prueth icssg-prueth-sr1
drivers/net/ethernet/ti/Makefile: icssg/icssg_classifier.o is added to multiple modules: icssg-prueth icssg-prueth-sr1

drivers/net/ethernet/ti/Makefile: icssg/icssg_ethtool.o is added to multiple modules: icssg-prueth icssg-prueth-sr1

Fix this by building a new module (icssg.o) for all the common objects.
Both the driver can then depend on this common module.

Some APIs being exported have emac_ as the prefix which may result into
confusion with other existing APIs with emac_ prefix, to avoid
confusion, rename the APIs being exported with emac_ to icssg_ prefix.

This also fixes below error seen when both drivers are built.

Merge branch 'introduce-switch-mode-support-for-icssg-driver'

MD Danish Anwar says:

====================
Introduce switch mode support for ICSSG driver

This series adds support for switch-mode for ICSSG driver. This series
also introduces helper APIs to configure firmware maintained FDB
(Forwarding Database) and VLAN tables. These APIs are later used by ICSSG
driver in switch mode.

Now the driver will boot by default in dual EMAC mode. When first ICSSG
interface is added to bridge driver will still be in EMAC mode. As soon as
second ICSSG interface is added to same bridge, switch-mode will be
enabled and switch firmwares will be loaded to PRU cores. The driver will
remain in dual EMAC mode if ICSSG interfaces are added to two different
bridges or if two different interfaces (One ICSSG, one other) is added to
the same bridge. We'll only enable is_switch_mode flag when two ICSSG
interfaces are added to same bridge.

We start in dual MAC mode. Let's say lan0 and lan1 are ICSSG interfaces

ip link add name br0 type bridge
ip link set lan0 master br0

At this point, we get a CHANGEUPPER event. Only one port is a member of
the bridge, so we will still be in dual MAC mode.

ip link set lan1 master br0

We get a second CHANGEUPPER event, the second interface lan1 is also ICSSG
interface so we will set the is_switch_mode flag and when interfaces are
brought up again, ICSSG switch firmwares will be loaded to PRU Cores.

There are some other cases to consider as well.

ip link add name br0 type bridge
ip link add name br1 type bridge

ip link set lan0 master br0
ip link set ppp0 master br0

Here we are adding lan0 (ICSSG) and ppp0 (non ICSSG) to same bridge, as
they both are not ICSSG, we will still be running in dual EMAC mode.

ip link set lan1 master br1
ip link set vpn0 master br1

Here we are adding lan1 (ICSSG) and vpn0 (non ICSSG) to same bridge, as
they both are not ICSSG, we will still be running in dual EMAC mode.

This is v6 of the series.

Changes from v5 to v6:
*) Removed __packed from structures in icssg_config.h file.
*) Added RB tags of Andrew Lunn <andrew@lunn.ch> to patch 2/3 and patch
3/3 of this series.

Changes from v4 to v5:
*) Rebased on 6.10-rc1.
*) Dropped the RFC tag.

Changes from v3 to v4:
*) Added RFC tag as net-next is closed now.
*) Modified the driver to remove the need of bringing interfaces up / down
for enabling / disabling switch mode. Now switch mode can be enabled
without bringig interfaces up / down as requested by Andrew Lunn
<andrew@lunn.ch>
*) Modified commit message of patch 3/3.

Changes from v2 to v3:
*) Dropped RFC tag.
*) Used ether_addr_copy() instead of manually copying mac address using
for loop in patch 1/3 as suggested by Andrew Lunn <andrew@lunn.ch>
*) Added helper API icssg_fdb_setup() in patch 1/3 to reduce code
duplication as suggested by Andrew Lunn <andrew@lunn.ch>
*) In prueth_switchdev_stp_state_set() removed BR_STATE_LEARNING as
learning without forwarding is not supported by ICSSG firmware.
*) Used ether_addr_equal() wherever possible in patch 2/3 as suggested
by Andrew Lunn <andrew@lunn.ch>
*) Fixed typo "nit: s/prueth_switchdevice_nb/prueth_switchdev_nb/" in
patch 2/3 as suggested by Simon Horman <horms@kernel.org>
*) Squashed "#include "icssg_mii_rt.h" to patch 2/3 from patch 3/3 as
suggested by Simon Horman <horms@kernel.org>
*) Rebased on latest net-next/main.

Changes from v1 to v2:
*) Removed TAPRIO support patch from this series.
*) Stopped using devlink for enabling switch-mode as suggested by Andrew L
*) Added read_poll_timeout() in patch 1 / 3 as suggested by Andrew L.
