MIN() is not used, MAX is only used once and can be replaced with the
max() version in libkern.h which operates on u_ints.

These examples show expected behavior of indent(1). They are meant to be used
together with a regression test mechanism, either Kyua, a Makefile or perhaps
something else. The mechanism should in essence do this:
indent -P${test}.pro < ${test}.0 > ${test}.0.run
and compare ${test}.0.stdout to ${test}.0.run. If the files differ or the exit
status isn't 0, the test failed.
* ${test}.pro is an indent(1) profile: a list of options passed through a file.
The program doesn't complain if the file doesn't exist.
* ${test}.0 is a C source file which acts as input for indent(1). It doesn't
have to have any particular formatting, since it's the output that matters.
* ${test}.0.stdout contains expected output. It doesn't have to be formatted in
Kernel Normal Form as the point of the tests is to check for regressions in
the program and not to check that it always produces KNF.

Aliases are normally given names that include a key that's unique for each
input object file. This, for example, ensures that aliases for identically
named local symbols in different object files don't conflict. However, in
some cases the static linker will leave an undefined alias after merging
identical weak symbols, resulting in a link error. A non-unique name allows
the aliases to be merged as well.

Refresh upstream driver before impending conversion to iflib.
Major new features:
- Support for Fortville-based 25G adapters
- Support for I2C reads/writes
(To prevent getting or sending corrupt data, you should set
dev.ixl.0.debug.disable_fw_link_management=1 when using I2C
[this will disable link!], then set it to 0 when done. The driver implements
the SIOCGI2C ioctl, so ifconfig -v works for reading I2C data,
but there are read_i2c and write_i2c sysctls under the .debug sysctl tree
[the latter being useful for upper page support in QSFP+]).
- Addition of an iWARP client interface (so the future iWARP driver for
X722 devices can communicate with the base driver).
- Compiling this option in is enabled by default, with "options IXL_IW" in
GENERIC.

If a file opened over a vnode has an advisory lock set at close,
vn_closefile() acquires additional vnode use reference to prevent
freeing the vnode in vn_close(). Side effect is that for device
vnodes, devfs_close() sees that vnode reference count is greater than
one and refuses to call d_close(). Create internal version of
vn_close() which can avoid dropping the vnode reference if needed, and
use this to execute VOP_CLOSE() without acquiring a new reference.
Note that any parallel reference to the vnode would still prevent
d_close call, if the reference is not from an opened file, e.g. due to
stat(2).

This implements hardware assisted quiet IE support. Quiet time is
an optional interval on DFS channels (but doesn't have to be DFS
only channels! sigh) where the station and AP can be quiet in order
to allow for channel utilisation measurements. Typically that's
stuff like radar detection, spectral scan, other-BSS frame sniffing,
checking how busy the air is, etc.
The hardware implements it as one of the generic timers, which is
supplied a period, offset from the trigger period and duration
to stay quiet. The AP can announce quiet time configurations which
change, and so this code also tracks that.
Implementation details:
* track the current quiet time IE
* compare the new one against the previous one - if only the TBTT
counter changes, don't update things
* If tbttcount=1 then program it into the hardware - that is when
it is easiest to program the correct starting offset (one TBTT +
configured offset).
* .. later on check to see if it can be done on any tbttcount
* If the IE goes away then remove the quiet timer and clear the
config
* Upon reset, state change, new beacon - clear quiet time IE
and just let it resync from the next beacon.
History:
This was work done initially by sibridgetech.com in 2011/2012/2013
as part of some FreeBSD wifi DFS contracting work they had for a
third party. They implemented the net80211 quiet time IE pieces
and had some test code for the station side which didn't entirely
use the timers correctly.
I figured out how to use the timers correctly without stopping/starting
the transmit DMA engine each time. When done correctly, the timer
just needs to be programmed once and left alone until the next
configuration change.
So, thanks to Himali Patel and Parthiv Shah for their work way
back then. I finally figured it out and finished it!
TODO:
* Now, I'd rather net80211 did the quiet time IE tracking and parsing,
pushing configurations into the driver is needed. I'll look at
doing that in a subsequent update.
* This doesn't handle multiple quiet time IEs, which will currently
just mess things up. I'll look into supporting that in the future
(at least by only obeying "one" of them, and then ignoring
subsequent IEs in a beacon/probe frame.)
* This also implements the STA side and not the AP side - the AP
side will come later, and involves taking various other intervals
into account (eg the beacon offset for multi-VAP modes, the
SWBA time, etc, etc) as well as obtaining the configuration when
a beacon is configured/generated rather than "hearing" an IE.
* .. investigate supporting quiet IE in mesh, tdma, ibss modes
* .. investigate supporting quiet IE for non-DFS channels
(so this can be done for say, 2GHz channels.)
* Chances are i should commit NULL methods for the ar5210, ar5211 HALs..
Tested:
* AR9380, STA mode - announcing quiet, removing quiet, changing quite
time config, whilst doing iperf testing;
* AR9380, AP mode.

excessive, but it minimizes diffs vs OpenZFS.

quiet IE - otherwise call the NULL method once, and then don't waste
time calling NULL
* on the beacon generation side - force a beacon regeneration each time
quiet time is enabled/disabled. Without this, enabling/disabling quiet
time IE would cause the beacon contents to be corrupted since none of
the "move contents around" logic (like for CSA and TIM handling) is implemented.
This changes the size of ieee80211_node so it requires a kernel recompile,
but no userland recompile.

using the ACPI C1/mwait sleep method.
Previously, the mwait instruction would return when an interrupt was
pending; however, the idle loop did not actually enable interrupts when
this occurred. This led to a situation where the idle loop could quickly
spin through the C1/mwait sleep method a number of times when an interrupt
was pending. (Eventually, the situation corrected itself when something
other than an interrupt triggered the idle loop to either enable interrupts
or schedule another thread.)

The primary end-goal of this drop is ease future merges with NetBSD and
collaborate further with the NetBSD project.
The goal was (largely, not completely as some items are still oustanding
in the NetBSD GNATS system) achieved by doing the following:
- Pushing as many changes required to port contrib/netbsd-tests
back to NetBSD as possible, then pull the upstream applied changes
back in to FreeBSD.
- Diff reduce with upstream where possible by:
-- Improving libnetbsd header, etc compat glue.
-- Using _SED variables to modify test scripts on the fly for items
that could not be upstreamed to NetBSD.
As a bonus for this work, this change also introduces testcases for
uniq(1).
Many thanks to Christos for working with me to get many of the changes
back into the NetBSD project.
