From: Yan-Hsuan Chuang <yhchuang@xxxxxxxxxxx> If the number of packets is less than the LPS threshold, driver can then enter LPS mode. And driver used to take RTW_LPS_THRESHOLD as the threshold. As the macro can not be changed after compiled, use a parameter instead. The larger of the threshold, the more traffic required to leave power save mode, responsive time could be longer, but also the power consumption could be lower.
