802.11 duplicate detection. Upon looking at the standard, we discover
that 802.11-2007 says:
"A receiving QoS STA is also required to keep only the most recent
cache entry per<Address 2, TID, sequence-number> triple, storing only
the most recently received fragment number for that triple. A receiving
STA may omit tuples obtained from broadcast/multicast or ATIM frames
from the cache."
To fix this, we just disable duplicate detection for multicast/broadcast
frames.

queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.

* WPA-None requires ap_scan=2:
The major difference between ap_scan=1 (default) and 2 is, that no
IEEE80211_IOC_SCAN* ioctls/functions are called, though, there is a
dependency on those. For example the call to wpa_driver_bsd_scan()
sets the interface UP, this never happens, therefore the interface
must be marked up in wpa_driver_bsd_associate(). IEEE80211_IOC_SSID
also is not called, which means that the SSID has not been set prior
to the IEEE80211_MLME_ASSOC call.
* WPA-None has no support for sequence number updates, it doesn't make
sense to check for replay violations..
* I had some crashes right after the switch to RUN state, issue is
that sc->sc_lastrs was not yet defined.

This framework allows drivers to abstract the rate control algorithm and
just feed the framework with the usable parameters. The rate control
framework will now deal with passing the parameters to the selected
algorithm. Right now we have AMRR (the default) and RSSADAPT but there's
no way to select one with ifconfig, yet.
The objective is to have more rate control algorithms in the net80211
stack so all drivers[0] can use it. Ideally, we'll have the well-known
sample rate control algorithm in the net80211 at some point so all
drivers can use it (not just ath).
[0] all drivers that do rate control in software, that is.
