wifi: rtw88: add WQ_PERCPU to alloc_workqueue users
Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
For more details see the Link tag below.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

Add support for the Enhanced Privacy Protection Key Exchange (EPPKE)

We already use textwrap when printing "doc" section about an attribute,
but only to indent the text. Switch to using fill() to split and indent
all the lines. While at it indent the text by 2 more spaces, so that it
doesn't align with the name of the attribute.
Before (I'm drawing a "box" at ~60 cols here, in an attempt for clarity):

It's a little hard to make sense of the output of --list-attrs,
it looks like a wall of text. Sprinkle a little bit of formatting -
make op and attr names bold, and Enum: / Flags: keywords italics.

wifi: mac80211: improve station iteration ergonomics
Right now, the only way to iterate stations is to declare an
iterator function, possibly data structure to use, and pass all
that to the iteration helper function. This is annoying, and
there's really no inherent need for it.
Add a new for_each_station() macro that does the iteration in
a more ergonomic way. To avoid even more exported functions, do
the old ieee80211_iterate_stations_mtx() as an inline using the
new way, which may also let the compiler optimise it a bit more,
e.g. via inlining the iterator function.

wl1251: Replace strncpy with strscpy in wl1251_acx_fw_version
strncpy() is deprecated [1] for NUL-terminated destination buffers since
it does not guarantee NUL termination. Remove the manual NUL termination
and replace strncpy() with strscpy() to ensure NUL termination of the
destination buffer.
Using strscpy_pad() to retain the NUL-padding behavior of strncpy() is
not needed because ->fw_ver is only used as a C-string.

====================
bnxt_en: Updates for net-next
This patchset updates the driver with a FW interface update to support
FEC stats histogram and NVRAM defragmentation. Patch #2 adds PTP
cross timestamps [1]. Patch #3 adds FEC histogram stats. Patch #4 adds
NVRAM defragmentation support that prevents FW update failure when NVRAM
is fragmented. Patch #5 improves RSS distribution accuracy when certain
number of rings is in use. The last patch adds ethtool
.get_link_ext_state() support.
====================
Map the link_down_reason from the FW to the ethtool link_ext_state
when it is available. Also log it to the link down dmesg when it is
available. Add 2 new link_ext_state enums to the UAPI:

bnxt_en: Use a larger RSS indirection table on P5_PLUS chips
The driver currently uses a chip supported RSS indirection table size
just big enough to cover the number of RX rings. Each table with 64
entries requires one HW RSS context. The HW supported table sizes are
64, 128, 256, and 512 entries. Using the smallest table size can cause
unbalanced RSS packet distributions. For example, if the number of
rings is 48, the table size using existing logic will be 64. 32 rings
will have a weight of 1 and 16 rings will have a weight of 2 when
set to default even distribution. This represents a 100% difference in
weights between some of the rings.
Newer FW has increased the RSS indirection table resource. When the
increased resource is detected, use the largest RSS indirection table
size (512 entries) supported by the chip. Using the same example
above, the weights of the 48 rings will be either 10 or 11 when set to
default even distribution. The weight difference is only 10%.
If there are thousands of VFs, there is a possiblity that we may not
be able to allocate this larger RSS indirection table from the FW, so
we add a check to fall back to the legacy scheme.
