Sometimes, BB might encounter RX problem on OFDM 6M. It's not quite
easy to happen, but if it happens, we will keep getting stuck on RX.
And, since we cannot properly receive layer 2 ACK, it also casues TX
problem, e.g. constantly retrying TX. Eventually, after some time, we
would get disconnected due to abnormal behavior.
Update break setting and phy status parsing time to make BB get out
of stuck state faster.

In current flow, FW is asynchronously loaded after alloc_hw(). It defers
the decision on FW feature map. It makes things difficult for us to decide
whether to hook chanctx ops, which should be decided while alloc_hw() is
calling. Still, asynchronous gets its advantages. So, we want to resolve
this without dropping them.
Based on multi-FW flag, RTW89_MFW_SIG, we can determine runtime FW is
multi-FW (MFW) or single FW (SFW). Both of them have a quite small chunk
for header at the head. The difference is that MFW doesn't describe version
code in its header while SFW does. So, we plan to extend MFW header for
version code. After that, in both cases, we can determine FW feature map by
just FW header. And, according to the map, we can decide chanctx.
So, we call request_partial_firmware_into_buf() to request a quite small
chunk before alloc_hw() to get a early FW feature map without affecting
things much and only use early map to decide whether to hook chanctx ops.
It means that if non-extended MFW is used at runtime, driver just acts
without chanctx as before. If extended MFW or SFW, which supports required
FW features, is used at runtime, driver can hook chanctx ops to mac80211 if
chip has configured support_chanctx_num > 0.
Besides, key point for now to support single one chanctx is whether HW scan
is supported at runtime. So, we configure all chip's support_chanctx_num to
1, and check if HW scan is supported at runtime via early FW feature map.

Some HW features are required if we hook chanctx ops to mac80211. With it,
mac80211 would expect the HW-supported variant ops exists on some behavior,
e.g. HW scan. But, HW features may depend on chip's FW or its development.
Besides, how many chanctx can be supported also depends on chip design.
We can neither decide whether to generally support chanctx ops nor how many
chanctx can be supported.
So, support_chanctx_num is added under chip info to deal with this by chip.
For now, all chip configure support_chanctx_num as 0. We haven't really
hook chanctx ops yet. So, chip can run without mac80211 chanctx as before.

Support mac80211 chanctx series ops. Still, currently support
single channel. Based on this premise, things should be similar
to before. So, we haven't dealt with relationship between vif
and chanctx in depth. Instead, we leave both ::assign_vif()
and ::unassign_vif() as noops for now.

After supporting more than one channel, we need entity mode to decide
how to set current channel(s) on the sub-entities. This decision may
happen on set_channel() and rtw89_core_set_chip_txpwr().
For now, we support single one channel and use only first HW entry,
i.e. RTW89_SUB_ENTITY_0, RTW89_MAC_0, RTW89_PHY_0. Without something
unexpected, the entity mode should always be RTW89_ENT_MODE_SCC after
recalcated, where SCC means single channel concurrency. So, an assert
is added in set_channel() and rtw89_core_set_chip_txpwr().

While idle, we need a default chandef to set channel for things,
such as scan. Before support of mac80211 chanctx, mac80211 would
configure a default one on ieee80211_hw::conf::chandef. And we
just queried it whenever we did set channel. However, after support
of mac80211 chanctx, the flow won't work like before.
Besides, we don't now query chandef from ieee80211_hw::conf::chandef
either. So, similar to mac80211 without using chanctx, we configure
the default chandef with ieee80211_channel of index 0 in 2GHz.
Although we have not added the support of mac80211 chanctx here,
this configuration should be compatible before that. So, we commit
this ahead.

Originally, we didn't support mac80211 chanctx, so it's expected that
ieee80211_hw::conf::chandef would be filled by mac80211. And then, we
could just query it whenever we need the current chandef.
However, we are planing to support mac80211 chanctx. After that, the
above assumption would be broken. So, we adjust a bit ahead to reduce
future works about mac80211 chanctx.
After this, we don't query ieee80211_hw::conf::chandef directly, and
we add a map, entity_map, to HAL to indicate which chandef came from
stack. And it will later be used to recalcate entity mode.

For future support on multiple channels, it would be disturbing if we
still allow scattered leaf functions of TX power to query and manage
channel related control by themselves.
So, query rtw89_chan only on top functions. Then, pass it via functions
to make sure that the values coming from the same struct rtw89_chan.
Besides, fix rtw8852a_set_txpwr_offset() from rtw8852a_set_txpwr_ctrl()
to rtw8852a_set_txpwr(). TX power offset should consider current band,
so move it to chip_ops::set_txpwr() which will be called every time that
channel is set.

Sometimes we need to write current rtw89_chan outside set_channel(),
e.g. during HW scan, we adjust it to align FW process through C2H.
However, we don't have full parameters to fill entire rtw89_chan.
And it will breakage if we update only part of current rtw89_chan.
That is what we don't want to see because most flows throughout
driver treat rtw89_chan as a whole.
So, we divide struct rtw89_chan to basic part and derived part. The
basic part contains the parameters which we are always able to know.
And the derived part will be calculated by the basic part. Then, a
central function, rtw89_chan_create(), is added to deal with this.

We are planning to support mac80211 chanctx. To reduce future works,
the driver architecture is adjusted first to isolate related things.
According to chip, our HW may have multiple sub-entities to support
multiple mac80211 chanctx. Struct rtw89_chan has been introduced for
things about channel/band/subband/... Now introduce struct rtw89_chan_rcd
to record difference after assigning new one of struct rtw89_chan.
We will implement and support chanctx with single channel first, i.e.
only use entry in RTW89_SUB_ENTITY_0, before handling dual channels.
Our hierarchy in planning will become as the following.
DEV
-> HAL
---> entity (manage status across sub-entities)
-----> sub-entity[*] (support mac80211 chanctx)
where each sub-entity contains one struct rtw89_chan.

Introduce struct rtw89_chan ahead to encapsulate stuffs from struct
rtw89_channel_params. These stuffs have a clone in HAL and are used
throughout driver. After multiple channels support, it's expected that
each channel instance has a configuration of them. So, we refine them
with struct rtw89_chan by precise type first, and will re-arrange HAL
by struct rtw89_chan in the following as well.
(No logic has changed.)

We need to invoke the callback of the changed band at the first
set_channel() after every power-off. Originally, we forced the
channel to be 0 when doing power-off, and then determined things
by comparing channel with 0.
However, deciding on such things by channel might be confusing.
It's also confusing to use this kind of decision when we consider
multiple channels in the follow-up patches. So, another flag,
entity_active, is added ahead to HAL to deal with this.
Besides, we also need to check if entity is active when we set
TX power.

to fit those demands. Separate the registered scan IE length by IC so
settings can be independent.
Since old firmware uses fewer page number, define a firmware feature to
be compatible with various firmware version.

The function alloc_workqueue() in rtw_core_init() can fail, but
there is no check of its return value. To fix this bug, its return value
should be checked with new error handling code.

SER (system error recovery) L1 (level 1) has a step-by-step handshake
process with FW. These handshakes still rely on B_AX_HS0ISR_IND_INT_EN.
So, even already during recovery, we enable this bit in IMR.

When the driver fails at ieee80211_alloc_hw() at the probe time, the
driver will free the 'hw' which is not allocated, causing a bug.
The following log can reveal it:
[ 15.981294] BUG: KASAN: user-memory-access in mutex_is_locked+0xe/0x40

The DPK is a kind of RF calibration whose algorithm is to fine tune
parameters and calibrate, and check the result. If the result isn't good
enough, it could adjust parameters and try again.
This issue is to read and show the result, but it could be a negative
calibration result that causes divisor 0 and core dump. So, fix it by
phy_div() that does division only if divisor isn't zero; otherwise,
zero is adopted.
