fcd9500f91 Fix some net80211 enum nits:
- ic_vap_create() uses an ieee80211_opmode argument
- ieee80211_rate2media() takes an ieee80211_phymode argument
- ieee80211_plcp2rate() takes an ieee80211_phytype argument
- cast to enum ieee80211_protmode and ieee80211_roamingmode to silence

bd56e71b4b Pull ieee80211_ratectl_node_init() calls from drivers into net80211.
This fixes hostap mode for at least ral(4) and run(4), because there is
no sufficient call into drivers which could be used initialize the node
related ratectl variables.

a7c6aabdc3 Instead of using the AMRR ratectl algo as default for drivers which have
the IEEE80211_C_RATECTL flag set, default to NONE for all drivers. Only if
a driver calls ieee80211_ratectl_init() check if the NONE algo is still
selected and try to use AMRR in that case. Drivers are still free to use
any other algo by calling ieee80211_ratectl_set() prior to the
ieee80211_ratectl_init() call.

After this change it is now safe to assume that a ratectl algo is always
available and selected, which renders the IEEE80211_C_RATECTL flag pretty
much useless. Therefore revert r211314 and 211546.

03286b3576 Initializes the ratectl for a node when the state is changed to RUN.
This prevents a kernel fault by dividing with zero because the initial
rate was 0 and didn't be initialized.

68cd814a8a Fixes NULL pointer reference that it's occurred when the state is
changed to RUN because ic->ic_newassoc isn't set anywhere now.  In the
previous bwi_newassoc() is used to initialize AMRR rate routines.

e50d35e6c6 Add new tunable 'net.link.ifqmaxlen' to set default send interface
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.

b6108616ac net80211 rate control framework (net80211 ratectl).
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.

37c3e5226c In bwi_newstate, only zero the bssid when we stop a STA. And only
when we've not stopped the card.  It hangs the system when we touch
the CSR after bwistop.

This fixes the hanging on kldunload.

5463c4a485 Overhaul monitor mode handling:
o replace DLT_IEEE802_11 support in net80211 with DLT_IEEE802_11_RADIO
  and remove explicit bpf support from wireless drivers; drivers now
  use ieee80211_radiotap_attach to setup shared data structures that
  hold the radiotap header for each packet tx/rx
o remove rx timestamp from the rx path; it was used only by the tdma support
  for debugging and was mostly useless due to it being 32-bits and mostly
  unavailable
o track DLT_IEEE80211_RADIO bpf attachments and maintain per-vap and
  per-com state when there are active taps
o track the number of monitor mode vaps
o use bpf tap and monitor mode vap state to decide when to collect radiotap
  state and dispatch frames; drivers no longer explicitly directly check
  bpf state or use bpf calls to tap frames
o handle radiotap state updates on channel change in net80211; drivers
  should not do this (unless they bypass net80211 which is almost always
  a mistake)
o update various drivers to be more consistent/correct in handling radiotap
o update ral to include TSF in radiotap'd frames
o add promisc mode callback to wi

12e36acb09 Bring in Andrew Thompson's port of Sepherosa Ziehau's bwi driver for
Broadcom BCM43xx chipsets.  This driver uses the v3 firmware that
needs to be fetched separately.  A port will be committed to create
the bwi firmware module.

The driver matches the following chips: Broadcom BCM4301, BCM4307,
BCM4306, BCM4309, BCM4311, BCM4312, BCM4318, BCM4319

The driver works for 802.11b and 802.11g.

Limitations:
	This doesn't support the 802.11a or 802.11n portion of radios.
	Some BCM4306 and BCM4309 cards don't work with Channel 1, 2 or 3.
	Documenation for this firmware is reverse engineered from
		 http://bcm.sipsolutions.net/
	V4 of the firmware is needed for 11a or 11n support
		 http://bcm-v4.sipsolutions.net/
	Firmware needs to be fetched from a third party, port to be committed

# I've tested this with a BCM4319 mini-pci and a BCM4318 CardBus card, and
# not connected it to the build until the firmware port is committed.
