[PATCH v6 1/8] mt76: mt7915: introduce mt7915_mcu_beacon_check_caps()

[PATCH v6 1/8] mt76: mt7915: introduce mt7915_mcu_beacon_check_caps()

[Shayne Chen]

From: Ryder Lee <ryder.lee@mediatek.com>

Beacon elements might be changed by hostapd configuraion, so driver
should compare both IEs and PHY capabilities to get the least common
denominator before association.

[PATCH v6 5/8] mt76: mt7915: rework starec TLV tags

[Shayne Chen]

Rework starec tags to the order which firmware expected. This also fixes
some weird behaviors during generating SPL of HE-MU.

[PATCH v6 7/8] mt76: mt7915: set VTA bit in tx descriptor

[Shayne Chen]

The VTA (Valid for Txd Arrival time) bit should be set in tx descriptor,
which is necessary for WM fw to schedule SPL (station priority list)
normally before generating txcmd.
If it's not set, some unexpected wcids may be involved in SPL.

[PATCH v6 8/8] mt76: mt7915: set muru platform type

[Shayne Chen]

Set muru platform type by mcu cmd to notify fw to init corresponding
algorithm.

Suggested-by: Money Wang <money.wang@mediatek.com>
Reviewed-by: Ryder Lee <ryder.lee@mediatek.com>
Signed-off-by: Shayne Chen <shayne.chen@mediatek.com>
---
v3: - fix endianess
    - rework muru ctrl function
v4: use put_unaligned_le32() to get rid of undefined behavior
v5: rebase to staging tree
