asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

This will allow the low level driver to take different actions for
different flows.

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the
channel context handling.

When compiling with clang 16.0.6 and CONFIG_FORTIFY_SOURCE=y, I've
noticed the following (somewhat confusing due to absence of an actual
source code location):

__read_overflow2_field(q_size_field, size);
The compiler actually complains on 'plfxlc_get_et_strings()' where
fortification logic inteprets call to 'memcpy()' as an attempt to copy
the whole 'et_strings' array from its first member and so issues an
overread warning. This warning may be silenced by passing an address
of the whole array and not the first member to 'memcpy()'.

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device. (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)
Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.
Rephrase the text in the kernel source where the word ordering is
wrong.

urbs does not be freed in exception paths in __lf_x_usb_enable_rx().
That will trigger memory leak. To fix it, add kfree() for urbs within
"error" label. Compile tested only.

mac80211 is fully switching over to the internal TX queue (iTXQ)
implementation. Update all drivers not yet providing the now mandatory
wake_tx_queue() callback.
As an side effect the netdev interfaces of all updated drivers will
switch to the noqueue qdisc.

GCC is upset that we check the return value of plfxlc_usb_dev()
even tho it can't be NULL:
drivers/net/wireless/purelifi/plfxlc/usb.c: In function ‘resume’:
drivers/net/wireless/purelifi/plfxlc/usb.c:840:20: warning: the comparison will always evaluate as ‘true’ for the address of ‘dev’ will never be NULL [-Waddress]
840 | if (!pl || !plfxlc_usb_dev(pl))
| ^
plfxlc_usb_dev() returns an address of one of the members of pl,
so it's safe to drop these checks.

This is a driver for pureLiFi X, XL, XC devices which use light to transmit
data, so they are not compatible with normal Wi-Fi devices. The driver uses
separate NL80211_BAND_LC band to distinguish from Wi-Fi. The driver is based
on 802.11 softMAC Architecture and uses native 802.11 for configuration and
management. Station and Ad-Hoc modes are supported.
The driver is compiled and tested in ARM, x86 architectures and compiled in
powerpc architecture. This driver implementation has been based on the zd1211rw
driver.
