[PATCH 1/9] wifi: mt76: mt7996: add max mpdu len capability

[PATCH 1/9] wifi: mt76: mt7996: add max mpdu len capability

[Shayne Chen]

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

Set max mpdu len to 11454 according to hardware capability.
Without this patch, the max ampdu length would be 3895 and count not get
expected performance.

[PATCH 2/9] wifi: mt76: mt7996: fix the capability of reception of EHT MU PPDU

[Shayne Chen]

From: Howard Hsu <howard-yh.hsu@mediatek.com>

This commit includes two changes. First, enable "EHT MU PPDU With 4x
EHT-LTF And 0.8us GI" in EHT Phy capabilities element since hardware
can support. Second, fix the value of "Maximum number of supported
EHT LTFs" in the same element, where the previous setting of 3 in
Bit 3-4 was incorrect.

[PATCH 6/9] wifi: mt76: mt7996: fix definition of tx descriptor

[Shayne Chen]

From: Benjamin Lin <benjamin-jw.lin@mediatek.com>

For mt7992 chipsets, the definition of TXD.DW6.BIT10~15 has different
interpretations on different frame types. Driver only needs to fill
MSDU_CNT for non-management frames.

Fixes: 408566db8cad ("wifi: mt76: connac: add new definition of tx descriptor")

[PATCH 7/9] wifi: mt76: mt7996: fix ldpc setting

[Shayne Chen]

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

The non-AP interfaces would not use conf->vht_ldpc so they never set
STA_CAP_VHT_LDPC even if peer-station support LDPC.
Check conf->vht_ldpc only for AP interface.

Without this patch, station only uses BCC to transmit packet in VHT mode.

[PATCH 8/9] wifi: mt76: mt7996: fix beacon command during disabling

[Shayne Chen]

From: Michael-CY Lee <michael-cy.lee@mediatek.com>

When stopping AP, mac80211 frees beacon template before it calls
driver's stop_ap operation. In other words, on the path of stopping
AP, ieee80211_beacon_get_template() must returns NULL in
mt7996_mcu_add_beacon(). In such case mt7996 immediately returns
-EINVAL without telling FW to disable the beacon.

This commit refactors mt7996_mcu_add_beacon() so that FW can be
correctly informed when disabling AP interface.

[PATCH 9/9] wifi: mt76: mt7996: add implicit beamforming support for mt7992

[Shayne Chen]

From: Howard Hsu <howard-yh.hsu@mediatek.com>

The configuration of mt7992 iBF has some differences to mt7996, rework
related code to make it work.
Also, most of our chipsets support iBF only on HT and VHT mode, except
mt7992 variant that has 5T on 5GHz band also supports iBF on HE and EHT
mode.
