[PATCH v3 1/2] mt76: connac: add mt76_connac_mcu_update_sta_cmd support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Sean Wang <sean.wang@xxxxxxxxxxxx>

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.

Signed-off-by: Sean Wang <sean.wang@xxxxxxxxxxxx>
---
v1->v2: no change
v2->v3: 1. rebase the latest mt76
	2. turn into using enum mt76_sta_info_state
	3. drop unneeded .state parameter passing in __mt7615_mcu_add_sta
	4. make mt76_connac_mcu_add_sta_cmd and
	   mt76_connac_mcu_update_sta_cmd static inline in
	   mt76_connac_mcu.h
