With multiple VIFS ath10k, and probably others, tries to find the
minimum txpower for all vifs and uses that when setting txpower in
the firmware.
If a second vif is added and starts to scan, it's txpower is not
initialized yet and it set to zero.
ath10k had a patch to ignore zero values, but then it is impossible
to actually set txpower to zero.
So, instead initialize the txpower to INT_MIN in mac80211, and let
drivers know that means the power has not been set and so should
be ignored.
This should fix regression in:

On the first wiphy, hw->priv will point to struct mt76_dev, which contains a
struct mt76_phy at the start. For the secondary wiphy, hw->priv will point
to a mt76_phy encapsulated in a driver specific struct
To simplify access to struct mt76_phy members from drivers, the driver specific
device struct is changed to add a union of struct mt76_dev and struct mt76_phy
as the first element

The logic for checking required NVM sections was recently fixed in
commit b3f20e098293 ("iwlwifi: mvm: fix NVM check for 3168
devices"). However, with that fixed the else is now taken for 3168
devices and within the else clause there is a mandatory check for the
PHY_SKU section. This causes the parsing to fail for 3168 devices.
The PHY_SKU section is really only mandatory for the IWL_NVM_EXT
layout (the phy_sku parameter of iwl_parse_nvm_data is only used when
the NVM type is IWL_NVM_EXT). So this changes the PHY_SKU section
check so that it's only mandatory for IWL_NVM_EXT.

Some tests shows that using AMSDU to aggregate TCP ACKs to specific
APs will degrade the throughput on 2.4G band in 20MHz bandwidth
(< 10 Mbps, should be ~100 Mbps for 2x2). Also found that there's
barely no negative impact if we disable TX AMSDU on 2.4G to connect
to other APs. So it seems like we can just tell mac80211 to not to
aggregate MSDUs when transmitting on 2.4G band.
Note that we still can TX AMSDU on 5G band and benefit from it by
having 50 ~ 70 Mbps throughput improvement.

According to some experiments, the original RF register protection
setting of 8822c cannot perfectly make sure that there is no hardware
PI write (direct) during direct write. Modify the setting so that the
hardware block of PI would be turned off via rtw8822c_rstb_3wire()
during the direct write, to avoid RF register racing.
Note that 8822b uses SIPI write (indirect), so 8822b does not
have such problem.

Driver could possibly be dead-locked while canceling works with
*_sync() with mutex lock held. Those cancel_delayed_work_sync()
functions will wait until the work is done, but if we hold the
lock, they will never acquire the lock.
To prevent this, simply release the lock and acquire again after
the works have been canceled. And to avoid the works being queued
again, check if the device is at RTW_FLAG_RUNNING state, otherwise
just return and do nothing.

When driver is coming up, mac80211 will set changed as ~0 (0xffffffff),
and driver could enter IDLE state (power off) before switching channel or
other config event. So move rtw_enter_ips() to the last, to make sure the
driver completed the config events before going to IDLE state.
So, moves leave/enter IPS config to be first/last one according to flag
IEEE80211_CONF_IDLE. If there're more configureations we want to add in
the future, they must locate between leave/enter IPS.

Most part of scan command data is always present, so no need
to keep it in TLV. Simplify scan command processing moving
most part of its parameters into a fixed part of
qlink_cmd_scan message.
Use fixed dwell time values for normal scan when device is not
connected, and allow wireless card decide on dwell times by
itself if it's operating as a STA and is connected. When
connected, card can select dwell times dynamically based on
traffic conditions to get best results.

Use MAJOR.MINOR format for QLink firmware protocol. MAJOR part is
incremented when backward compatibility is broken. Normally this
part should not be incremented unless there is a good reason for
that. MINOR part is incremented each time when new features are
added to qlink.h, e.g. new TLVs, events, commands. These changes
should not break backward compatibility. For instance, older
firmware versions may not be able to parse new flags or send new
types of events, but this does not impact normal system operations.
As part of initialization sequence, driver requests protocol version
from firmware and refuses to start in case there is a mismatch in MAJOR
part of the version.
