To avoid aggregating rate control probing packets with other traffic, and to
ensure that the probing rate gets used, probing packets get assigned a different
internal queueing priority.
This causes packets to be transmitted in a different order, which is compensated
by the receiver side reordering.
However, if A-MPDU is disabled, this reordering can become visible to upper
layers on the receiver side. Disable the priority change if A-MPDU is disabled.

When the hardware falls back to lower rates for a transmit attempt, only the
first status report will show the number of retries correctly. The frames
that follow will report the correct final rate, but number of retries set to 0.
This can cause the rate control module to vastly underestimate the number of
retransmissions per rate.
To fix this, we need to keep track of the initial requested tx rate per packet
and pass it to the status information.
For frames with tx status requested, this is simple: use the rate configured
in info->control.rates[0] as reference.
For no-skb tx status information, we have to encode the requested tx rate in
the packet id (and make it possible to distinguish it from real packet ids).
To do that, reduce the packet id field size by one bit, and use that bit to
indicate packet id vs rate.
This change also improves reporting by filling the status rate array with
rates from first rate to final rate, taking the same steps as the hardware
fallback table. This matters in corner cases like MCS8 on HT, where the
fallback target is MCS0, not MCS7.

Add a structure for power parameters including base,
offset, limit and a function to get tx power parameters.
Then, refine flow to get tx power index through the
function.

Since this macro definition has different values in different chipset,
the current defined macro value is for 8822b. This will cause the
settings of 8822c be incorrect.
Remove RTW_MAX_POWER_INDEX and use max_power_index in struct rtw_chip_info
to make sure the value of different chipset is right.

Support more regulatory domains including IC, KCC,
ACMA, CHILE, UKRAINE, and MEXICO. Corresponding tx
power limits for these regulatory domains are added
in tx power limit table. Besides, tx power limits in
some case are also updated to follow RF v20 for better
tx power indexes.
Channel plan mapping table are upgraded to consider
more 2G and 5G channel plans combination cases. It
allow us to identify different situations more accuratly
by channel plan IDs. In addition, mapping table for
country code and channel plan ID and mapping table
for country code and tx power limit are also updated
to follow RF v20. It allow the new enrties in tx power
limit table to be applied correctly.

If phy rate is decreased, sub bandwidth may be chosen by RA.
We consider possible power limits and apply the min one;
otherwise, the tx power index may be larger than spec.
And we cross-reference power limits of vht and ht with
20/40M bandwidth in 5G to avoid values are not assigned.

limit for the world-wide power settings.

Tx power limit is stored separately by 2G and 5G.
But driver did not get tx power limit from 5G and causes incorrect tx
power. Check if the channel is beyond 2G and get the corresponding tx
power limit.
