This is a subset of what's in the linux 802.11ac implementation.
I've verified that the bits that mention an 802.11ac draft are
still the same in 802.11ac-2013 and noted it accordingly.
This is for the most part one big no-op.
Obtained from: 802.11ac-2013.pdf
* Implement a new ratectl method, which defaults to returning nothing;
* Add a top level sysctl (net.wlan.X.rate_stats) to extract it;
* Add ratectl info for the 'amrr' module.
Tested:
* urtwn(4), STA mode

For hz=1000 any number, greater than 4194 causes integer overflow;
this change casts the number to uint64_t before operating with it.

m is not guaranteed to be valid after m_cat() returns. The effects of this
are most noticeable when INVARIANTS is enabled, since m's header length
field is given a value of 0xdeadc0de by the trash dtor.

Drivers should set their own filters via ic_scan_start()/ic_scan_end()
callbacks; and we don't need frames other than beacons or probe responses.
(Note: this was a noop since r287197 due to promiscuous mode with bridge
workaround)

- In case, when we are doing <smth> -> INIT (FEXT_REINIT) -> <smth2>
state transition, cancel_scan() may be called in the first transition.
Reenqueue second state transition, so things will be executed in order.
- Discard any AUTH+ state transition request when INIT -> SCAN
transition is not done.
- Allow to track discarded state transitions via 'state' debugging
category.
Tested with:
* RTL8188EU, HOSTAP mode.
* RTL8188CUS, STA mode.
* Intel 3945BG, IBSS and STA modes.

scan_curchan_task() functions)
(This part should fix the problem, described in
https://lists.freebsd.org/pipermail/freebsd-wireless/2016-January/006420.html)
- Rename ss_scan_task into ss_scan_start (better describes it's
current purpose)
- Utilize taskqueue_*_timeout() functions instead of current mechanism:
* reschedule scan_curchan_task() via taskqueue_enqueue_timeout()
for every 'maxdwell' msecs (will replace infinite loop + sleeping
for 'maxdwell' period via cv_wait());
* rerun the task immediately when an external event occurs
(instead of waking it up via cv_signal())
Also, use mtx_sleep() to wait for null frame transmission
(allows to drop conditional variable).

* Intel 3945BG, STA mode;
* RTL8188EU, STA mode.

we're assuming hz=1000 and not gracefully handling when it isn't.
The math involved will return 0 for hz < 1000, which it is on some
platforms and on DragonflyBSD.
This doesn't fix it, it:
* converts one manual use over to use the macro, and
* comments where it needs some thought/fixing.
I'll think about this a bit more before fixing it.

wpa_supplicant actually calls the wpa ioctl with cipher 0 as part
of the teardown process and this returns an ioctl error.
It's required as part of the (hopefully!) upcoming encrypted
IBSS support which does indeed do the above as part of interface
setup and then exits ungracefully when it gets an ioctl error.
(I'll fix wpa_supplicant in a later commit as part of other work.)
I've seen some cases where we get stuck in a loop constantly trying to
negotiate A-MPDU TX which is definitely not supposed to happen.
This will let me see if it's something funky with the retry count or
not.
This call may be used when device cannot continue to operate normally
(e.g., throws firmware error, watchdog timer expires)
and need to be restarted.
