Since target accepts one parameter as a retry count, ath10k pass retry_long along with TID and station's mac address to target in the command and store this if TID_RETRY_CONF_CHANGED. And pass enable/disable aggregation for the TID if TID_AGGR_CONF_CHANGED is passed. Depends on the changed parameter the respective value stored in arsta struct. Suppose if the station entry is not mentioned in the command, the configuration will be applied for all the connected stations in the vif. And this configuration will be stored in arvif to apply this configuration for newly connecting station.
