[PATCH 1/2] ath10k: implement uapsd autotrigger command

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

 



From: Janusz Dziedzic <janusz.dziedzic@xxxxxxxxx>

New wmi-tlv firmware for qca6174 has u-UAPSD
autotrigger service. If it is enabled firmware
generates trigger frames automatically as
configured.
