f7f5c0102c [iwm] No need for iwm_assoc() in AUTH->ASSOC transition.
* Hence no need to keep stuff in separate iwm_assoc() function, just
  inline the stuff into iwm_newstate().

b80e7ca55b [iwm] Properly implement iwm_wme_update callback function.
* Inspired by iwn(4) and Linux iwlwifi.

* Read wme parameters into a buffer within struct iwm_vap in
  iwm_wme_update().

* If we aren't associated yet, the new settings will soon be sent
  by iwm_mvm_mac_ctxt_changed() during association.

* If we are already associated, explicitly call iwm_mvm_mac_ctxt_changed()
  from iwm_wme_update() to send the new settings to the firmware.

* Change iwm_mvm_ac_to_tx_fifo mapping, to fit the freebsd net80211
  WME stream class numbering, instead of Linux's enum ieee80211_ac_numbers.

702287e43a [iwm] Process multiple frames per RX buffer.
* Factor out iwm_handle_rxb() function from iwm_notif_intr().

* Removing the IWM_FH_RCSR_CHNL0_RX_CONFIG_SINGLE_FRAME_MSK flag allows
  the device to put multiple frames (both command responses and 80211
  frames) into a single RX buffer.

* Uses m_copym() to split up the receive buffers when multiple 80211
  frames are received in one RX buffer. The effect is basically the same
  as when using m_split(), but we want to keep the original mbuf around
  when calling iwm_mvm_rx_rx_mpdu() to make error handling a bit easier
  for now.

* Contains a small optimization to avoid the m_copym() when only a single
  80211 frame is received in one RX buffer (i.e. matching the existing
  behaviour).

  fw_has_api now uses the isset macro instead of a simple logical-and.

bdba683047 [if_iwm] Partly sync if_iwm_binding.c to Linux iwlwifi code.
* Store macid and color values in struct iwm_vap, to avoid hardcoded
  constants a bit.

* Add iwm_mvm_binding_remove_vif() function (will be used in disconnecting
  from an access point without resetting the whole device).

* Not adding code from Linux iwlwifi yet, to handle one PHY context to
  be bound to several VAPs/virtual-interfaces, it's definitely not needed
  in the near future.

c44c4d8d92 [iwm] Allow listening on both chains/atennas to get diversity.
This might improve throughput slightly when far from the accesspoint,
apparently by allowing the firmware to listen on either of the two
antennas (if there are two, i.e. on 7260/7265/8260), whichever has
a better reception.

08e1076cf6 [iwm] Add basic powermanagement support via ifconfig wlan0 powersave.
* The DEVICE_POWER_FLAGS_CAM_MSK flag was removed in the upstream iwlwifi
  in Linux commit ceef91c89480dd18bb3ac51e91280a233d0ca41f.

* Add sc_ps_disabled flag to struct iwm_softc, which corresponds to
  mvm->ps_disabled in struct iwl_mvm in Linux iwlwifi.

* Adds a hw.iwm.power_scheme tunable which corresponds to the power_scheme
  module parameter in Linux iwlwifi. Set this to 1 for completely
  disabling power management, 2 (default) for balanced powermanagement,
  and 3 for lowerpower mode (which does dtim period skipping).

* Imports the constants.h file from iwlwifi as if_iwm_constants.h.

* This doesn't allow changing the powermanagement setting while connected,
  also one can only choose between enabled and disabled powersaving with
  ifconfig (so switching between balanced and low-power mode requires
  rebooting to change the tunable).

* After any changes to powermanagement (i.e. "ifconfig wlan0 powersave" to
  enable powermanagement, or "ifconfig wlan0 -powersave" for disabling
  powermanagement), one has to disconnect and reconnect to the accespoint
  for the change to take effect.

f631357540 net80211 drivers: fix rate setup for EAPOL frames, obtain Tx parameters
directly from the node.

- Use ni_txparms directly instead of calculating them manually every time
- Move M_EAPOL flag check upper; otherwise it may be skipped due to
'ucastrate' / 'mcastrate' check
- Use 'mgtrate' for control frames too (see ifconfig(8), mgtrate parameter)
- Add few more M_EAPOL checks where it was missing (zyd(4), ural(4),
urtw(4))
- Few unrelated cleanups

Tested with:
 - Intel 6205 (iwn(4)), STA mode;
 - WUSB54GC (rum(4)), HOSTAP mode + RTL8188EU (rtwn(4)), STA mode.

* In iwm_scan_end, if the scan is still running, we now abort it, in order
  to keep the firmware scanning state in sync.

* Try to make things a bit simpler, by reacting on the
  IWM_SCAN_OFFLOAD_COMPLETE and IWM_SCAN_COMPLETE_UMAC notifications,
  instead of IWM_SCAN_ITERATION_COMPLETE and
  IWM_SCAN_ITERATION_COMPLETE_UMAC. This should be fine since we always
