I would say this patch can be merged with 3/12 where FW_START_WORKING_PDA_DSP
is actually used.

[PATCH 03/12] wifi: mt76: mt7996: add dsp firmware download

[Shayne Chen]

From: Peter Chiu <chui-hao.chiu@mediatek.com>

Add DSP firmware for phy-related control. The firmware is transparent to
driver, but it's necessary for the firmware download process.

Yeah, a function is preferred. I think Andrew Morton says: prefer C over
CPP

[PATCH 04/12] wifi: mt76: mt7996: fix bss wlan_idx when sending bss_info command

[Shayne Chen]

From: Peter Chiu <chui-hao.chiu@mediatek.com>

The bmc_tx_wlan_idx should be the wlan_idx of the current bss rather
than peer AP's wlan_idx, otherwise there will appear some frame
decryption problems on station mode.

Fixes: 98686cd21624 ("wifi: mt76: mt7996: add driver for MediaTek Wi-Fi 7 (802.11be) devices")

[PATCH 08/12] wifi: mt76: mt7996: set ifs time by mcu command

[Shayne Chen]

From: Peter Chiu <chui-hao.chiu@mediatek.com>

There's a race between driver and fw on some tx/rx control registers
when setting ifs, which will cause accidental hw queue pause problems.
Avoid this by setting ifs time with bss_info mcu command.

nit: I think it is better to do it in the other way around since the band can
be even 6GHz. Something like:

	bool is_2ghz_band = phy->mt76->chandef.chan->band == NL80211_BAND_2GHZ

or even just use phy->mt76->chandef.chan->band directly.

Lorenzo

[PATCH 09/12] wifi: mt76: mt7996: use correct phy for background radar event

[Shayne Chen]

From: StanleyYP Wang <StanleyYP.Wang@mediatek.com>

If driver directly uses the band_idx reported from the radar event to
access mt76_phy array, it will get the wrong phy for background radar.
Fix this by adjusting the statement.
