* 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
receive calibration.

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.

appropriate state handling takes place, not doing so results in the
device doing nothing until manual intervention.

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:

vs
test 00:26:5a:c6:14:1a 40 54M -92:-95 200 E WME HTCAP ATH
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
it results in:

module_register: module pci/ipw already exists!
Module pci/ipw failed to register: 17
while trying to load the module due to an entry in loader.conf. With this
commit we get the expected:
module ipw already present!

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.

- instead of calling iwn_plcp_signal() for every frame, map the expected
value directly within wn->ridx
- concat plcp, rflags and xrflags, there is no clean byte boundary within
the flags, for example the antenna setting uses bit 6, 7 and 8
- there is still need for a custom rate to plcp mapping, as those expected
by the hardware are not conform to the std
On legacy channels every once in a while the firmware throws a SYSASSERT
on line 208. On HT channels though this does always happen and I'm not
aware of any workaround currently.
