Implement SCM_PIDFD, a new type of CMSG type analogical to SCM_CREDENTIALS,
but it contains pidfd instead of plain pid, which allows programmers not
to care about PID reuse problem.
We mask SO_PASSPIDFD feature if CONFIG_UNIX is not builtin because
it depends on a pidfd_prepare() API which is not exported to the kernel
modules.

mlxsw: Cleanups in router code
This patchset moves some router-related code from spectrum.c to
spectrum_router.c where it should be. It also simplifies handlers of
netevent notifications.
- Patch #1 caches router pointer in a dedicated variable. This obviates the
need to access the same as mlxsw_sp->router, making lines shorter, and
permitting a future patch to add code that fits within 80 character
limit.
- Patch #2 moves IP / IPv6 validation notifier blocks from spectrum.c
to spectrum_router, where the handlers are anyway.
- In patch #3, pass router pointer to scheduler of deferred work directly,
instead of having it deduce it on its own.
- This makes the router pointer available in the handler function
mlxsw_sp_router_netevent_event(), so in patch #4, use it directly,
instead of finding it through mlxsw_sp_port.
- In patch #5, extend mlxsw_sp_router_schedule_work() so that the
NETEVENT_NEIGH_UPDATE handler can use it directly instead of inlining
equivalent code.
- In patches #6 and #7, add helpers for two common operations involving
a backing netdev of a RIF. This makes it unnecessary for the function
mlxsw_sp_rif_dev() to be visible outside of the router module, so in
patch #8, hide it.

This code handles NETEVENT_DELAY_PROBE_TIME_UPDATE, which is invoked every
time the delay_probe_time changes. mlxsw router currently only maintains
one timer, so the last delay_probe_time set wins.
Currently, mlxsw uses mlxsw_sp_port_lower_dev_hold() to find a reference to
the router. This is no longer necessary. But as a side effect, this makes
sure that only updates to "interesting netdevices" (ones that have a
physical netdevice lower) are projected.
Retain that side effect by calling mlxsw_sp_port_dev_lower_find_rcu() and
punting if there is none. Then just proceed using the router pointer that's
already at hand in the helper.
Note that previously, the code took and put a reference of the netdevice.
Because the mlxsw_sp pointer is now obtained from the notifier block, the
port pointer (non-) NULL-ness is all that's relevant, and the reference
does not need to be taken anymore.

by default. The counters visible in ethtool -S are also affected,

ice: Improve miscellaneous interrupt code
Jacob Keller says:
This series improves the driver's use of the threaded IRQ and the
communication between ice_misc_intr() and the ice_misc_intr_thread_fn()
which was previously introduced by commit 1229b33973 ("ice: Add low
latency Tx timestamp read").
First, a new custom enumerated return value is used instead of a boolean for
ice_ptp_process_ts(). This significantly reduces the cognitive burden when
reviewing the logic for this function, as the expected action is clear from
the return value name.
Second, the unconditional loop in ice_misc_intr_thread_fn() is removed,
replacing it with a write to the Other Interrupt Cause register. This causes
the MAC to trigger the Tx timestamp interrupt again. This makes it possible
to safely use the ice_misc_intr_thread_fn() to handle other tasks beyond
just the Tx timestamps. It is also easier to reason about since the thread
function will exit cleanly if we do something like disable the interrupt and
call synchronize_irq().
Third, refactor the handling for external timestamp events to use the
miscellaneous thread function. This resolves an issue with the external
time stamps getting blocked while processing the periodic work function
task.
Fourth, a simplification of the ice_misc_intr() function to always return
IRQ_WAKE_THREAD, and schedule the ice service task in the
ice_misc_intr_thread_fn() instead.
Finally, the Other Interrupt Cause is kept disabled over the thread function
processing, rather than immediately re-enabled.
Special thanks to Michal Schmidt for the careful review of the series and
pointing out my misunderstandings of the kernel IRQ code. It has been
determined that the race outlined as being fixed in previous series was
actually introduced by this series itself, which I've since corrected.

The second pull request for v6.5. We have support for three new
Realtek chipsets, all from different generations. Shows how active
Realtek development is right now, even older generations are being
worked on.
Note: We merged wireless into wireless-next to avoid complex conflicts
between the trees.
Major changes:
rtl8xxxu
* RTL8192FU support
rtw89
* RTL8851BE support
rtw88
* RTL8723DS support
ath11k
* Multiple Basic Service Set Identifier (MBSSID) and Enhanced MBSSID
Advertisement (EMA) support in AP mode
iwlwifi
* support for segmented PNVM images and power tables
* new vendor entries for PPAG (platform antenna gain) feature
cfg80211/mac80211
* more Multi-Link Operation (MLO) support such as hardware restart
* fixes for a potential work/mutex deadlock and with it beginnings of
the previously discussed locking simplifications

tools: ynl-gen: code gen improvements before ethtool
I was going to post ethtool but I couldn't stand the ugliness
of the if conditions which were previously generated.
So I cleaned that up and improved a number of other things
ethtool will benefit from.

Netlink specs support both events and notifications (former can
define their own message contents). Plug in missing code to
generate types, parsers and include events into notification
tables.

Don't modify the raw dicts (as loaded from YAML) to pretend
that the notify attributes also exist on the ops. This makes
the code easier to follow.

Common notification handler was supposed to be a way for the user
to parse the notifications from a socket synchronously.
I don't think we'll end up using it, ynl_ntf_check() works for
all known use cases.

Reading attr type with mnl_attr_get_type() for each condition
leads to most conditions being longer than 80 chars.
Avoid this by reading the type to a variable on the stack.

Code gen currently prints:
}
else if (...
This is really ugly. Fix it by delaying printing of closing
brackets in anticipation of else coming along.
