* Firmware versions 21 and 22 generate some IWM_DEBUG_LOG_MSG notifications,
which seem to be harmless. Avoid spamming the system log with
"frame ... UNHANDLED (this should not happen)" messages.

* If device family is 8000 then iwm_pcie_load_cpu_sections()
won't be called at all (iwm_pcie_load_cpu_sections_8000() is
called in that case) so this piece of code never gets called.

* LAR can be disabled with the hw.iwm.lar.disable tunable now.
* On Family 8000 devices we need to check the lar_enabled flag from
nvm_data in addition to the TLV_CAPA_LAR_SUPPORT flag from the firmware.
* Add a separate IWM_DEBUG_LAR debugging flag.

* This change also fixes a possible issue in the existing smart-fifo code,
which set the IWM_SF_CFG_DUMMY_NOTIF_OFF bit on AC8260 chipsets, although
that's only used in iwlwifi for Family 8000 chipsets connected via SDIO
interface.

* Since a RUN -> INIT/SCAN transition seems to immediately destroy the
ieee80211_node for the AP, we can't read the in_assoc value from there.
Instead just directly pass that information via a boolean_t argument.
* Adds iwm_mvm_rm_sta_id() function, which just unconditionally removes
the station from the firmware.
* The iwm_mvm_rm_sta() function shouldn't actually remove the station from
firmware when we are still associated (i.e. during a RUN -> INIT/SCAN
transition).
* So when disassociating we will first call iwm_mvm_rm_sta() to drain the
queues/fifos. Later during disassociation we will then use
iwm_mvm_rm_sta_id() to actually remove the station.

* Add a per-vap ps_disabled flag, and use it for a workaround which fixes
an association issue when powersaving is enabled.
* Compute flag that should correpsond to the mvmif->bss_conf.ps flag in
Linux's iwlwifi (e.g. this disallows powersaving when not associated
yet).

* Power management handling is per-vap, not per-node, so we should pass
the iwm_vap in these arguments.

* Otherwise we would never update powersaving settings until we complete
an association, after the first authentication attempt.
* This corresponds to what Linux iwlwifi seems to do.

* Tear down the relevant firmware state (i.e. the station, the vif binding)
in these transition cases.
* Before this case would leave the firmware state lying around, resulting
in errors and firmware panics in the subsequent association attempts.

* This adds iwm_mvm_rm_sta(), which will be used to tear down firmware
state for better/cleaner iwm_newstate() handling.
* Makes iwm_enable_txq() and iwm_mvm_flush_tx_path() non-static, add
the declarations to if_iwm_util.h for now.

* Hence no need to keep stuff in separate iwm_assoc() function, just
inline the stuff into iwm_newstate().

* 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.

* 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).

* 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.

* 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.

IWM_UCODE_TLV_FLAGS_D3_CONTINUITY_API,

* Also remove definitions and code for dealing with the v1 time-event api.
* Remove unneeded calc_rssi() function.

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.

* Adds IWM_DEBUG_TEMP debug message type, for printing messages related
to temperature sensors and thermal/TDP infos.
* The firmware regularly sends us DTS measurement notifications, so just
print the temperature value as a debugging message.
(Adrian's addition):
* Eventually this can be used by the driver to limit transmit rate / power to
try and do some thermal throttling.
