494571986b add 0x8b, lifted from Linux iwlegacy/commands.h
This is "STA invalid". I saw it during some 4965 testing (kern/183260)
and I still have no idea what is causing it.

8cf53c1244 Begin fleshing out a knob to enable/disable bluetooth coexistence.
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.)

2e6fe9b630 Temporarily disable multi-rate retry (link quality) and eliminate rate
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

c68534f1d5 Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI
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.

4030a4b2a3 Cap the number of streams supported to two for now.
I haven't yet reviewed the Intel driver(s) in more depth to see if
there are 1x1 NICs that report they support 2 transmit/receive chains..
if so then we'll have to update this.

Tested:

* Intel 4965, which is a 2x2 device with 3 RX and 2 TX chains.

f8bf74f232 Implement basic 802.11n awareness in the PHY and AMRR rate control code.
* 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

* Make it configurable live, rather than only after it's done its initial

bf6998c568 The firmware of 4965 series adapters seems to die while trying to send
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
