[PATCH v3 2/4] wifi: mt76: mt7996: Add mcu commands for getting sta tx statistic

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

 



Per peer Tx/Rx statistic can only be obtained by querying WM when WED is
on. This patch switches to periodic event reporting in the case of WED
being enabled.
