[PATCH v2 4/4] wifi: rtw89: extend PHY status parser to support WiFi 7 chips

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

 



PHY status IEs is used to have more information about received packets,
such as RSSI and EVM. For each PHY IE type, it has different predefined
PHY IE length, and the length are changed, so add them for WiFi 7 chips
accordingly.
