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.

1b6b62c900 Fixes for monitor mode:
- Do not call iwn_calib_reset() for monitor mode. We do not want to query
  information and do runtime calibration while in monitor mode. Poking the
  firmware with adjustments for calibration results in firmware asserts.
  This could happened on RUN -> RUN transition only.
- Adjust blink rate for monitor mode. It's supposed to not freak out and
  turn off after a while.
- While here, remove one useless assignment of calib.state, it gets
  overwritten later in the function.

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.

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.

578fece5ff Revert iwn channel-argument handling of set_txpower() to r201822
Pass the channel argument as a real argument and not through
RXON.  The RXON version seems to have problem with both the older
228.57.2.23 firmware and the latest 228.61.2.24 version resulting
in device initialization errors like:

  wpa_supplicant[2928]: Failed to initiate AP scan.
  kernel: firmware error log:
  kernel: error type      = "SYSASSERT" (0x00000005)
  kernel: program counter = 0x0000147C
  kernel: source line     = 0x0000058B

  ...
  kernel: iwn0: iwn_config: could not set TX power
  kernel: iwn0: iwn_init_locked: could not configure device, error 35

By passing the current channel to hal->set_txpower() the firmware
error is fixed, at least for the 4965 chipset of my Thinkpad and
the ones tested by Bernhard.

o replace DLT_IEEE802_11 support in net80211 with DLT_IEEE802_11_RADIO

  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

  unavailable
o track DLT_IEEE80211_RADIO bpf attachments and maintain per-vap and

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

  a mistake)

5efea30f03 Create a taskqueue for each wireless interface which provides a serialised
sleepable context for net80211 driver callbacks. This removes the need for USB
and firmware based drivers to roll their own code to defer the chip programming
for state changes, scan requests, channel changes and mcast/promisc updates.
When a driver callback completes the hardware state is now guaranteed to have
been updated and is in sync with net80211 layer.

This nukes around 1300 lines of code from the wireless device drivers making
them more readable and less race prone.

The net80211 layer has been updated as follows
 - all state/channel changes are serialised on the taskqueue.
 - ieee80211_new_state() always queues and can now be called from any context
 - scanning runs from a single taskq function and executes to completion. driver
   callbacks are synchronous so the channel, phy mode and rx filters are
   guaranteed to be set in hardware before probe request frames are
   transmitted.

  header contents
o move fast-frame aggregation from ath to net80211 (conditional on
  IEEE80211_SUPPORT_SUPERG):
  - aggregation is now done in ieee80211_start; it is enabled when the
    packets/sec exceeds ieee80211_ffppsmin (net.wlan.ffppsmin) and frames
    are held on a staging queue according to ieee80211_ffagemax
    (net.wlan.ffagemax) to wait for a frame to combine with
  - drivers must call back to age/flush the staging queue (ath does this
    on tx done, at swba, and on rx according to the state of the tx queues
    and/or the contents of the staging queue)
  - remove fast-frame-related data structures from ath
  - add ieee80211_ff_node_init and ieee80211_ff_node_cleanup to handle
    per-node fast-frames state (we reuse 11n tx ampdu state)
o change ieee80211_encap calling convention to include an explicit vap
  so frames coming through a WDS vap are recognized w/o setting M_WDS

With these changes any device able to tx/rx 3Kbyte+ frames can use fast-frames.

9f2c7365ab We can not call iwn_start directly in the interrupt

iwn_start assumes that we do not have that mutex held.

Resolve this issue with what we do for other NICs by
splitting the iwn_start procedure into two parts,
iwn_start() do the locking, and iwn_start_locked()
assumes that the mutex is being held.  This resolves
panic when WITNESS is enabled.
