* iwm_xmit_queue_drain() calls ieee80211_free_node(), removing a possible
memory leak, compared to using just mbufq_drain().
* Remove duplicate mbufq_drain() from iwm_mvm_rm_sta(), this should be
handled in the caller.

* Limiting the channel list with "ifconfig wlan0 chanlist ..." now will
actually set the list of channels scanned by iwm.
Tested:
* Intel 7260, STA mode, setting chanlist to 1-14 and 36-254, and indeed it does what
it should!
It turns out the /next/ dragonflybsd git actually uses the scan channel list,
so just kick this along to make the next commit easier.

From the original commit:
==
* Actually look at the first channel in the list. If it's a 2.4GHz channel,
set IWM_PHY_BAND_24 flag. The IWM_PHY_BAND_5 flag is 0 anyway, so we
don't need to look further.
* While there factor out the iwm_mvm_rrm_scan_needed() tlv capability check.

However, this only really does the latter. The sc_ic channel list isn't the
scan channel list, it's the /whole list/ for the set of active channels,
so I don't know what the right thing to do is here.
So I'll commit this as an intermediary commit and we'll have to revisit whether
to finish the refactor as-is.
Tested:
* Intel 7260, STA mode

* 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.

* This fixes cases where the group id of wide commands got lost, e.g. this
happened to the IWM_SCAN_ABORT_UMAC command.

* 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.
Obtained from: dragonflybsd.git 62a4e7957a736b4de38938b02fa7eb9b45bc5d0d
* 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.
Obtained from: dragonflybsd.git 85d1c6190c4c3564b1a347f253e823aa95c202b2
* 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).

* Fixes oversight from commit 757eecf0e6c92745aa2eee95811e573c8300850e.
fw_has_api now uses the isset macro instead of a simple logical-and.

* 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.

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.

* 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.

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