a7408b56e5 ynl: support binary and integer sub-type for indexed-array
Add binary and integer sub-type support for indexed-array to display bond
arp and ns targets. Here is what the result looks like:

 # ip link add bond0 type bond mode 1 \
   arp_ip_target 192.168.1.1,192.168.1.2 ns_ip6_target 2001::1,2001::2
 # ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/rt_link.yaml \
   --do getlink --json '{"ifname": "bond0"}' --output-json | jq '.linkinfo'

    "arp-ip-target": [
      "192.168.1.1",
      "192.168.1.2"
    ],
    [...]
    "ns-ip6-target": [
      "2001::1",
      "2001::2"
    ],

aa6485d813 ynl: rename array-nest to indexed-array
Some implementations, like bonding, has nest array with same attr type.
To support all kinds of entries under one nest array. As discussed[1],
let's rename array-nest to indexed-array, and assuming the value is
a nest by passing the type via sub-type.

0e9c127729 ethtool: add interface to read Tx hardware timestamping statistics
Multiple network devices that support hardware timestamping appear to have
common behavior with regards to timestamp handling. Implement common Tx
hardware timestamping statistics in a tx_stats struct_group. Common Rx
hardware timestamping statistics can subsequently be implemented in a
rx_stats struct_group for ethtool_ts_stats.

1d056bf9a4 netlink: specs: define ethtool header flags
When interfacing with the ethtool commands it's handy to
be able to use the names of the flags. Example:

    ethnl.pause_get({"header": {"dev-index": cfg.ifindex,
                                "flags": {'stats'}}})

Note that not all commands accept all the flags,
but the meaning of the bits does not change command
to command.

====================
wireless-next patches for v6.10

The first "new features" pull request for v6.10 with changes both in
stack and in drivers. The big thing in this pull request is that
wireless subsystem is now almost free of sparse warnings. There's only
one warning left in ath11k which was introduced in v6.9-rc1 and will
be fixed via the wireless tree.

Realtek drivers continue to improve, now we have support for RTL8922AE
and RTL8723CS devices. ath11k also has long waited support for P2P.

This time we have a small conflict in iwlwifi, Stephen has an example
merge resolution which should help with fixing the conflict:

 * RTL8922AE Wi-Fi 7 PCI device support

rtw88
 * RTL8723CS SDIO device support

iwlwifi
 * don't support puncturing in 5 GHz
 * support monitor mode on passive channels
 * BZ-W device support
 * P2P with HE/EHT support

ath11k
 * P2P support for QCA6390, WCN6855 and QCA2066

929107d3d2 dt-bindings: net: dwmac: Document STM32 property st,ext-phyclk
The Linux kernel dwmac-stm32 driver currently supports three DT
properties used to configure whether PHY clock are generated by
the MAC or supplied to the MAC from the PHY.

Originally there were two properties, st,eth-clk-sel and
st,eth-ref-clk-sel, each used to configure MAC clocking in
different bus mode and for different MAC clock frequency.
Since it is possible to determine the MAC 'eth-ck' clock
frequency from the clock subsystem and PHY bus mode from
the 'phy-mode' property, two disparate DT properties are
no longer required to configure MAC clocking.

Linux kernel commit 1bb694e208 ("net: ethernet: stmmac: simplify phy modes management for stm32")
introduced a third, unified, property st,ext-phyclk. This property
covers both use cases of st,eth-clk-sel and st,eth-ref-clk-sel DT
properties, as well as a new use case for 25 MHz clock generated
by the MAC.

The third property st,ext-phyclk is so far undocumented,
document it.

Below table summarizes the clock requirement and clock sources for
supported PHY interface modes.
 __________________________________________________________________________

7003de8a22 dt-bindings: bluetooth: add 'qcom,local-bd-address-broken'
Several Qualcomm Bluetooth controllers lack persistent storage for the
device address and instead one can be provided by the boot firmware
using the 'local-bd-address' devicetree property.

The Bluetooth bindings clearly states that the address should be
specified in little-endian order, but due to a long-standing bug in the
Qualcomm driver which reversed the address some boot firmware has been
providing the address in big-endian order instead.

The only device out there that should be affected by this is the WCN3991
used in some Chromebooks.

Add a 'qcom,local-bd-address-broken' property which can be set on these
platforms to indicate that the boot firmware is using the wrong byte
order.

Note that ChromeOS always updates the kernel and devicetree in lockstep
so that there is no need to handle backwards compatibility with older
devicetrees.

ca7e324e8a compiler_types: add Endianness-dependent __counted_by_{le,be}
Some structures contain flexible arrays at the end and the counter for
them, but the counter has explicit Endianness and thus __counted_by()
can't be used directly.

To increase test coverage for potential problems without breaking
anything, introduce __counted_by_{le,be}() defined depending on
platform's Endianness to either __counted_by() when applicable or noop
otherwise.
Maybe it would be a good idea to introduce such attributes on compiler
level if possible, but for now let's stop on what we have.

6e9b01909a net: remove gfp_mask from napi_alloc_skb()
__napi_alloc_skb() is napi_alloc_skb() with the added flexibility
of choosing gfp_mask. This is a NAPI function, so GFP_ATOMIC is
implied. The only practical choice the caller has is whether to
set __GFP_NOWARN. But that's a false choice, too, allocation failures
in atomic context will happen, and printing warnings in logs,
effectively for a packet drop, is both too much and very likely
non-actionable.

This leads me to a conclusion that most uses of napi_alloc_skb()
are simply misguided, and should use __GFP_NOWARN in the first
place. We also have a "standard" way of reporting allocation
failures via the queue stat API (qstats::rx-alloc-fail).

The direct motivation for this patch is that one of the drivers
used at Meta calls napi_alloc_skb() (so prior to this patch without
__GFP_NOWARN), and the resulting OOM warning is the top networking
warning in our fleet.

Pull x86 fixes from Thomas Gleixner:

 - Ensure that the encryption mask at boot is properly propagated on
   5-level page tables, otherwise the PGD entry is incorrectly set to
   non-encrypted, which causes system crashes during boot.

 - Undo the deferred 5-level page table setup as it cannot work with
   memory encryption enabled.

 - Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset
   to the default value but the cached variable is not, so subsequent
   comparisons might yield the wrong result and as a consequence the
   result prevents updating the MSR.

 - Register the local APIC address only once in the MPPARSE enumeration
   to prevent triggering the related WARN_ONs() in the APIC and topology
   code.

 - Handle the case where no APIC is found gracefully by registering a
   fake APIC in the topology code. That makes all related topology
   functions work correctly and does not affect the actual APIC driver
   code at all.

 - Don't evaluate logical IDs during early boot as the local APIC IDs
   are not yet enumerated and the invoked function returns an error
   code. Nothing requires the logical IDs before the final CPUID
   enumeration takes place, which happens after the enumeration.

 - Cure the fallout of the per CPU rework on UP which misplaced the
   copying of boot_cpu_data to per CPU data so that the final update to
   boot_cpu_data got lost which caused inconsistent state and boot
   crashes.

 - Use copy_from_kernel_nofault() in the kprobes setup as there is no
   guarantee that the address can be safely accessed.

 - Reorder struct members in struct saved_context to work around another
   kmemleak false positive

 - Remove the buggy code which tries to update the E820 kexec table for
   setup_data as that is never passed to the kexec kernel.

 - Update the resource control documentation to use the proper units.

 - Fix a Kconfig warning observed with tinyconfig

Pull networking fixes from Jakub Kicinski:
 "Including fixes from CAN, netfilter, wireguard and IPsec.

  I'd like to highlight [ lowlight? - Linus ] Florian W stepping down as
  a netfilter maintainer due to constant stream of bug reports. Not sure
  what we can do but IIUC this is not the first such case.

  Current release - regressions:

   - rxrpc: fix use of page_frag_alloc_align(), it changed semantics and
     we added a new caller in a different subtree

   - xfrm: allow UDP encapsulation only in offload modes

  Current release - new code bugs:

   - tcp: fix refcnt handling in __inet_hash_connect()

   - Revert "net: Re-use and set mono_delivery_time bit for userspace
     tstamp packets", conflicted with some expectations in BPF uAPI

  Previous releases - regressions:

   - ipv4: raw: fix sending packets from raw sockets via IPsec tunnels

   - devlink: fix devlink's parallel command processing

   - veth: do not manipulate GRO when using XDP

   - esp: fix bad handling of pages from page_pool

  Previous releases - always broken:

   - report RCU QS for busy network kthreads (with Paul McK's blessing)

   - tcp/rds: fix use-after-free on netns with kernel TCP reqsk

   - virt: vmxnet3: fix missing reserved tailroom with XDP

  Misc:

   - couple of build fixes for Documentation"
