e4e7938ae5 Stick the if_drv_flags access (check and modify) behind the ifq lock.
Although access to the flags to check/set OACTIVE is racy due to how
the default if_start() function works, this should remove any races
with read/modify/write between threads.

b09e37a185 Fix a panic introduced in a previous commit - non-beaconing modes (eg STA)
don't setup the avp mcast queue.

This is a bit annoying though - it turns out the mcast queue isn't
initialised for STA mode but it's then touched to see whether anything
is in it.  That should be fixed in a subsequent commit.

5f3818a56e Revert r175376 and tune cpufreq(4) frequency comparison logic instead.
Instead of using 25MHz equality threshold, look for the nearest value when
handling dev.cpu.0.freq sysctl and for exact match when it is expected.

ACPI may report extra level with frequency 1MHz above the nominal to
control Intel Turbo Boost operation. It is not a bug, but feature:
dev.cpu.0.freq_levels: 2934/106000 2933/95000 2800/82000 ...
In this case value 2933 means 2.93GHz, but 2934 means 3.2-3.6GHz.

I've found that my Core i7-870 based system has Intel Turbo Boost disabled
by default and without this change it was absolutely invisible and hard
to control.

7199b6f7ee Fix wrong asresp frame parsing in iwi_checkforqos().
After 8.0-RELEASE, iwi(4) doesn't send any data frames in infrastructure
mode.

Bacause of the condition `while (frm < efrm)', IEEE80211_VERIFY_LENGTH()
was checking item length beyond the ieee80211_frame region, and returned
from iwi_checkforqos() without setting flags, capinfo and associd.

In infrastructure mode associd is required, so this problem causes
discarding mbuf in ieee80211_start().

6bfe9e8ccf Optimize tls_get_addr_common(). The change provides around 30% speedup
for TLS microbenchmark using global-dynamic TLS model on amd64 (which is
default for PIC dso objects).

Split the slow path into tls_get_addr_slow(), for which inlining is
disabled. This prevents the registers spill on tls_get_addr_common()
entry.

Provide static branch hint to the compiler, indicating that slow path
is not likely to be taken.

While there, do some minimal style adjustments.

9c85ff9164 Don't flood the cabq/mcastq with frames.
In a very noisy 2.4GHz environment (with HT/40 enabled, making it worse)
I saw the following occur:

* the air was considered "busy" a lot of the time;
* the cabq time is quite short due to staggered beacons being enabled;
* it just wasn't able to keep up TX'ing CABQ frames;
* .. and the cabq would swallow up all the TX ath_buf's.

This patch introduces a twiddle which allows the maximum cabq depth to be
set, forcing further frames to be dropped.

It defaults to the TX buffer count at the moment, so the default behaviour
isn't changed.

I've also started fleshing out a similar setup for the data path, so
it doesn't swallow up all the available TX buffers and preventing management
frames (such as ADDBA) out.

c5940c30a7 Document that we may end up with some suboptimal handling of data
frames with stations in power saving mode.

I'm not (yet) sure how to handle TX'ing aggregates frames to stations
that are in power saving mode, or whether that's even a feasible thing
to do. So in order to (mostly) not forget, leave a couple of comments
in the code.

The code presently assumes that the aggregation TID state for an ath_node
is locked not by the ath_node lock or a node+TID lock, but behind the
hardware queue said TID maps to.  This assumption is going to be
incorrect for stations in power saving mode as we'll be TX'ing frames
on the multicast queue.

In any case, I'm afraid its a "later problem". :/

24c8f29cf4 Partially undo r228693, by removing NO_WFORMAT.clang in fsdb's Makefile,
and fixing the format string in sbin/fsdb/fsdbutil.c instead.

Note the remark "Work around a problem with format string warnings and
ntohs macros" was actually incorrect.  The DIP(dp, di_nlink) macro
invocation actually returned an int, due to its ternary expression, even
though the di_nlink members of struct ufs1_dinode and struct ufs2_dinode
are both defined as int16_t.

6aa83769fd After r232745, which makes sure __bswap16(), ntohs() and htons() return
__uint16_t, we can partially undo r228668.

Note the remark "Work around a clang false positive with format string
warnings and ntohs macros (see LLVM PR 11313)" was actually incorrect.

Before r232745, on some arches, the ntohs() macros did in fact return
int, not uint16_t, so clang was right in warning about the %hu format
string.

63d094a7e2 Add casts to __uint16_t to the __bswap16() macros on all arches which
