[PATCHv7 6/6] mac80211: Add api to support configuring TID specific configuration

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

 



Implement drv_set_tid_config api to allow TID specific
configuration. This per-TID configuration
will be applied for all the connected stations when MAC is NULL.
