bf6998c568 The firmware of 4965 series adapters seems to die while trying to send
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:
test            00:26:5a:c6:14:1a   40   54M -71:-95  200 E    WME HTCAP ATH
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.

129145a426 Add module version to iwi/ipw/wpi and iwn.
The version is used to check if a module is already preset, not setting
it results in:

can't re-use a leaf (ipw)!
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!

4f6760821e Only update the scheduler's byte count table for aggregation queues.
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.

1647639a26 Prepare for transmitting frames at MCS rates:
- 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

c9ce626212 Disable background scan support for 4965 adapters.
On legacy channels every once in a while the firmware throws a SYSASSERT

aware of any workaround currently.

9ff2129fbe Pull some features out of the firmware:
- If a ENH_SENS TLV section exit the firmware is capable of doing
  enhanced sensitivity calibration.
- Newer devices/firmwares have more calibration commands therefore
  hardcoding the noise gain/reset commands no longer works. It is
  supposed to use the next index after the newest calibration type
  support. Read the command index of the TLV section if available.

9dd0e40b62 Add some new features:

- set the IWN_FLAG_HAS_11N bit if the EEPROM says the device has 11n
  support.
