This is "STA invalid". I saw it during some 4965 testing (kern/183260)
and I still have no idea what is causing it.

Some firmware versions seem to get very unhappy if they're sent btcoex
commands when they don't actually have bluetooth hardware in them.
So, disable sending them those commands.
Tested:
* 5100 (which has bluetooth, no problems)
* 4965 (which doesn't have bluetooth, but didn't seem to crash)
* 6200 (no bluetooth, seems to get unhappy being sent bluetooth commands.)
index lookups.
* My recent(ish) change to iwn(4) and the net80211 rate control API to
support 11n rates broke the link quality table use. So, until I or
someone else decides to fix it, let's just disable it for now.
* Teach iwn_tx_data_raw() to use the iwn_rate_to_plcp() function.
* Eliminate two uses of the net80211 rate index lookup functions - they
are only for legacy rates and they're not needed here.
This fixes some invalid looking rate control TX issues that showed up
on my 4965 but it doesn't fix the two TX hangs I've noticed. Those look
like DMA related issues.
Tested:
* 4965, STA mode
* 5100, STA mode
command register. The lazy BAR allocation code in FreeBSD sometimes
disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR. Thus, the bit is no longer
a reliable indication of capability, and should not be checked. This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.
This changes fixes some recent reports of disk controllers and their
associated drives/enclosures disappearing during boot.

Whilst here, add a few extra fields in preparation for further iwn(4)

there are 1x1 NICs that report they support 2 transmit/receive chains..
if so then we'll have to update this.

* Add 802.11n 2ghz and 5ghz tables, including legacy rates and up to
MCS23 rates (3x3.)
* Populate the rate code -> rate index lookup table with MCS _and_
normal rates, but _not_ the basic rate flag. Since the basic rate flag
is the same as the MCS flag, we can only use one.
* Introduce some accessor inlines that do PLCP and rate table lookup/access
and enforce that it doesn't set the basic rate bit. They're not
designed for MCS rates, so it will panic.
* Start converting drivers that use the rate table stuff to use the
accessor inlines and strip the basic flag.
* Teach AMRR about basic 11n - it's still as crap for MCS as it is
being used by iwn, so it's not a step _backwardS_.
* Convert iwn over to accept 11n MCS rates rather than 'translate' legacy
to MCS rates. It doesn't use a lookup table any longer; instead it's a
function which takes the current node (for HT parameters) and the
rate code, and returns the hardware PLCP code to use.
Tested:
* ath - it's a no-op, and it works that way
* iwn - both 11n and non-11n
It's not enabled by default in net80211 so this is a no-op unless
if you enable it (ifconfig wlan0 powersave).
Tested:
* iwn0: <Intel WiFi Link 5100> mem 0xf4300000-0xf4301fff irq 17 at device 0.0 on pci3
TODO:
* .. test on all the other NICs
* See if I have to disable it during scan and such
* Make it configurable live, rather than only after it's done its initial

the TX queue is empty, there won't be a TX done notification, effectly
resulting in an mbuf leak. The correct way to handle this is to free
up mbufs on both BA and TX done notifications up to the last sent seqno.

probe requests at 1Mbps while being associated on a 5GHz channel. Sending
those at 6Mbps does work, so use that instead during a background scan.
This workaround allows us to re-enable background scan support for the
4965 adapters.
Also, just enabling one antenna on 5GHz results in better reception of
beacons:

Due to roam:rssi thresholds set to 7 by default it might have been
impossible to associate to that network. While here use
IEEE80211_IS_CHAN_5GHZ() to determine the band.
The version is used to check if a module is already preset, not setting

The other queues, especially the command queue, uses the FIFO mode
which doesn't require the byte count table because queued entries are
processed in order.
