Subject: [PATCH v2 1/3] mt76: connac: add mt76_connac_mcu_update_sta_cmd support

From: Sean Wang <[email protected]>

Add mt76_connac_mcu_update_sta_cmd support that is the prerequisite patch
for we are able to update the station record with the current state the
station has into the offload firmware at runtime.

Add mt7921_mcu_sta_update support to make we are able to update the station

runtime. That is the prerequisite patch to fix .sta_state incorrect
implementation for the mt7921 driver.

Subject: [PATCH v2 3/3] mt76: mt7921: fix sta_state incorrect implementation

From: Sean Wang <[email protected]>

When .sta_state is implemented, mac80211 assumes that the station entry is
usable after the NOTEXIST->NONE transition.

So we should create the sta entry as early as possible in order that
mac80211 pass assoc/auth frames to mt76 with the newly created sta entry,
and add .sta_assoc to mt76 core to refresh the sta entry again when sta is
being associated.

Fixes: 8aa5a9b7361c ("mt76: mt7921: enable deep sleep at runtime")
Signed-off-by: Sean Wang <[email protected]>
---
v1->v2: Put back the careless change not belonged to the patch to keep
mt7921_mcu_sta_add for BC entry and mt76_connac_mcu_uni_add_bss
on the association.

Please turn this into an enum:

enum mt76_sta_info_state {
MT76_STA_INFO_STATE_NONE,
MT76_STA_INFO_STATE_AUTH,
MT76_STA_INFO_STATE_ASSOC
};

The _1 _2 _3 suffixes are not that readable and add extra confusion by
not matching the numeric values.

it seems to me this parameter is used only by mt7921, right? So we can drop
this chunk

Do we really need these 2 routines? Maybe better to have them static inline in
mt76_connac_mcu.h
