786b72c5bc Shuffle code around a bit. Mostly to group functional connected things,
others to get the same order as the OpenBSD code.

5fd12c76a8 Rename some stuff in favour of the OpenBSD names:
- prefer EDCA over WME
- qid for a TXQ ID
- reg for register values

4e61a8e57c Fix WME/QoS handling:
- move the TX queue selection into iwn_tx_data/iwn_tx_data_raw
- extract traffic identifier and use it
- do not expect ACKs for frames marked as such

baa8b4ad20 Remove if_ierrors which do not necessarily indicate a RX error, also
do account send packets. While here use the IWN_TX_FAIL constant.

3096855e8c Instead of hardcoding TX rates and using that to fill the retry table

b558f70709 Fixes for firmware handling:

9289984d4b Instead of trying to figure out which rxon.flags to clear, restart
from scratch. Remove htole16() calls, rxon.chan is an uint8_t,
ieee80211_chan2ieee() does return an ic_ieee as an int, but I heavily
doubt a htole16() will buy us anything here.

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.

2d5c617a52 For 6000 series and newer devices the DC calibration results are no
longer requested of the boot firmware. Instead of sending those results
to the runtime firmware the firmware is told to do the DC calibration
itself.

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.

- unobscure some of the code by moving it into its own functions
- get rid of some magic numbers
- create similar structure as the reference driver has, this should
  make further syncs easier

2e3a546047 Add a workaround for a bug in the firmware regarding the transition
from passive to active scans. Basicly disable it by increasing the
amount packets to be received to an amount which can't be reached
