From: Ching-Te Ku <ku920601@realtek.com>
MLO link combinations such as MLD2L1R_NONMLD let the firmware switch
the WL RF-path binding at runtime between 2+0, 0+2 and 1+1, instead of
keeping it fixed for the lifetime of the link. struct
rtw89_btc_wl_mlo_info already carries mrcx_mode, mrcx_act_hwb_map and
mrcx_bt_slot_rsp to describe that runtime state, and
rtw89_fw_h2c_cxdrv_mlo_v2() already forwards them to the firmware, but
nothing in the driver ever wrote these three fields. _set_bind_info()
and _set_coex_binding() both read mrcx_act_hwb_map to resolve which
HW-band a given WL RF-path currently serves while in this mode, and
with the field always zero they always resolved to the same band,
regardless of what the firmware actually switched to.
Add rtw89_btc_ntfy_mrcx_info(), a notify entry a caller can use to push
the current RF-path switch state into those three fields and let the
coex engine react to it. Mirroring the driver's existing per-HW-band
link_mode array, a mode change updates whichever MAC index the active
HW-band map selects, and a dual-band-MCC link mode is required before
any change is applied, since the RF-path binding is only ambiguous in
that state. A dedicated reason code and notify counter are added for
this entry so it can be told apart from other re-run triggers in coex
dumps.
This only adds the coex-internal entry point; nothing in the driver
calls it yet, since the trigger for a firmware-side RF-path switch
needs to be wired up from the MLO channel-context code.

Currently, we reclaim TXBD only when the available resource is 0.
When two ACs share the same DMA channel, the lower-priority AC
occupies the whole channel, which affects the higher-priority
AC's throughput.
Add RTW89_PCI_TXBD_RECLAIM_TH to reclaim early once the
available resource falls below it, improving TX
fairness between ACs sharing a DMA channel.

Instead of deriving the CCK RX gain compensation from BW20/BW40 gain bias
and CCK RPL offset fields, write the calibration efuse gain value directly
to the efuse bias field.

The thermal trim value in efuse can be -16 and +16 for productions.
Correct the range accordingly. Otherwise, wrong trim value 0 is adopted.

From: Zong-Zhe Yang <kevin_yang@realtek.com>
The RTW89_QUIRK_DISABLE_2GHZ only blocked registering NL80211_BAND_2GHZ
in wiphy->bands, but didn't handle other SW logic. Other SW flow still
determined things based on chip->support_bands, and caused inconsistent
behavior.
Introduce supported_bands bitmap which is set by intersection of quirks
and chip->support_bands when initializing core. Besides, initialize quirks
when allocating HW.

Previously, because all chipsets support 2 GHz, default channel was
always one of 2 GHz. However, after adding RTW89_QUIRK_DISABLE_2GHZ,
wiphy might not really register NL80211_BAND_2GHZ.
Refine logic to get default channel based on bitmap of supported bands.
Besides, throw an error if there is no any supported bands to use.

From: Zong-Zhe Yang <kevin_yang@realtek.com>
The rx_status->band expects enum nl80211_band instead of enum rtw89_band.
Convert band from enum rtw89_band to enum nl80211_band before assignment.
Fortunately, this problematic code had previously produced valid values,
but fixing it should be better.

From: Po-Hao Huang <phhuang@realtek.com>
Add missing flow when switching MLO links. Fix unexpected RTL8922D
FW behavior. In MLSR mode, when only single link information is
initialized, enabling hardware to switch link arbitrarily causes FW
errors. This register will be set only in the future patches where
change link is a must, e.g. eMLSR.
Recalculate the current active band and do corresponding TX
settings before authentication and returning from power save mode,
to keep hardware from sending packets from inactive bands.

RTL8922D supports dynamic antenna gain compensation via ACPI Realtek
Antenna Gain (RTAG), so turn on the flag in its chip info.
