Sometimes mac80211 will ask us to flush the hardware queues. To flush them, first we need to get the corresponding priority queues from the RQPN mapping table. Then we can check the available pages are equal to the originally reserved pages, which means the hardware has returned all of the pages it used to transmit. Note that now we only check for 100 ms for the priority queue, but sometimes if we have a lot of traffic (ex. 100Mbps up), some of the packets could be dropped.
