RTL8812AU uses one set of TX power tracking tables for RFE 3, and
another set for everything else.
Move pwr_track_tbl from struct rtw_chip_info to struct rtw_rfe_def in
order to load the right set of tables for each RFE (RF front end) type.

All the chips supported so far have a TX page size of 128 bytes.
Change the type of the page_size member of struct rtw_chip_info from u8
to u16 in order to support RTL8821AU (page size of 256 bytes) and
RTL8812AU (page size of 512 bytes). Also change the types of several
related variables and function parameters from u8 to u16.
The TX page size is used, among other things, to construct the beacon,
null data, QOS null data, and PS poll templates which are uploaded to
the chip's reserved page. Each template needs to be aligned on a
multiple of the TX page size. Power saving can't work if the TX page
size is wrong.

txagc_remnant_ofdm member of struct rtw_dm_info should be different for
each RF path, so make it an array of size RTW_RF_PATH_MAX (4).
Until now all the chips using this had only one RF path, but RTL8812AU
has two, and RTL8814AU has four.

RTL8811AU fails to perform the 4-way handshake when the AP is too far
because it transmits the EAPOL frames at MCS9 and when that doesn't
work it retries 48 times with the same rate, to no avail.
Retrying 48 times with the same rate seems pointless. Set the
appropriate field in the TX descriptor to allow it to use lower rates
when retrying.
Set it for RTL8723D and RTL8703B because they interpret this field the
same way as RTL8811A.
The newer RTL8822C, RTL8822B, RTL8821C seem to interpret this field in
the TX descriptor differently, so leave it alone for those chips.
Tested with RTL8811AU and RTL8723DU.

Setting of channel and TX power depend on channel contexts, but original
code cannot handle combination of MCC (multi-channel concurrency) and MLO
well. So according to active interfaces, we generate a table for current
channel contexts. And then based on entity mode, we get the corresponding
channel context to apply during channel or TX power setting. When MLO is
supported, there will be dual-PHY and we will apply the channel context of
the 2nd link to the 2nd PHY.

To set channel well for combination of MCC (multi-channel concurrency) and
impending MLO support, we need a method to manage relation between active
interfaces and channel contexts. If an interface owns at least one active
link, we call it an active interface. We add a list to manage active ones.
Basically, the list follows the active order except for the below case. To
be compatible with legacy behavior, the first interface that owns the first
channel context will put at the first entry in the list when recalculating.
Besides, MCC can also select and fill roles based on the above active list.

To prevent chip overheating, reduce TX duty as the mechanism of thermal
protection. When temperature is raising over a threshold, send a firmware
command to reduce TX duty. If temperature is still raising, higher level
is adopted to have lower active duration.
The equation and unit of thermal values are different from chip to chip,
so define constant thresholds of thermal value to corresponding absolute
temperature of 110 and 120 degree Celsius.
Latter patch will decide which thermal threshold is adopted, and current
is still not enable thermal protection.

Register wiphy after reading out chipid, so the chipid can be
used to determine chip features and not advertise WPA3/SAE
support to userspace on WILC3000. Note that wilc_netdev_cleanup()
will deregister the wiphy in fail path.

The wilc_create_wiphy() is not used outside of cfg80211.c .
Make the function static and remove its entry from cfg80211.h

Add error handling to chip_wakeup() and propagate the errors throughout
the entire driver. Add error handling to acquire_bus()/release_bus() and
host_sleep_notify()/host_wakeup_notify() functions as a result as well.
Fill the error handling to all call sites.

Neither chip_allow_sleep()/chip_wakeup() is used outside of wlan.c .
Make both functions static and remove both the exported symbol and
entries from wlan.h .
Make chip_allow_sleep() return error code in preparation for the
follow up patches.
Move acquire_bus() and release_bus() to avoid forward declaration
of chip_allow_sleep()/chip_wakeup().

Reduce the use of wilc_get_chipid(), use cached chip ID wherever
possible. Remove duplicated partial chip ID read implementations
from the driver. Update wilc_get_chipid() to always read the chip
ID out of the hardware and update the cached chip ID, and make it
return a proper return value instead of a chipid. Call wilc_get_chipid()
early to make the cached chip ID available to various sites using
is_wilc1000() to access the cached chip ID.

Document compatible string for the WILC3000 chip. The chip is similar
to WILC1000, except that the register layout is slightly different and
it does not support WPA3/SAE.

The WILC3000 can suspend and enter low power state. According to local
measurements, the WILC3000 consumes the same amount of power if the slot
is powered up and WILC3000 is suspended, and if the WILC3000 is powered
off. Use the former option, keep the WILC3000 powered up as that allows
for things like WoWlan to work.
Note that this is tested on WILC3000 only, not on WILC1000 .

to employ the ';' as a statement separator, except when ',' are
