d22a753788 We need to defer passing the DELBA request to the firmware until the aggr

94f926381b Fix a TX aggregation issue, if after the last compressed BA notification
the TX queue is empty, there won't be a TX done notification, effectly
resulting in an mbuf leak. The correct way to handle this is to free
up mbufs on both BA and TX done notifications up to the last sent seqno.

fe30cce04e Use suspend/resume methods provided by net80211. This ensures that the

7d5ab4d392 On state changes from RUN to anything else the AGGR sessions are

8d184570b3 The DC calibration result obtained during initialization can't be
passed over to the runtime firmware on 6050 devices. Instead let
the runtime firmware do the calibration itself. This fixes support

0d22f0d915 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 -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.

aafd4acbe2 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!

a58fc6f0fd 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

8cc008f8dd 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
