The improved tx queue handling mechanism between openwifi_tx() and openwifi_tx_interrupt():
...
1. Consider more corner cases: interrupt missing will cause a bd in the driver ring will never be cleaned. this need to be considered in the openwifi_tx()
2. Another corner case in openwifi_tx_interrupt: a packet is just sent and an interrupt calls the routine, but it finds that the bd in the driver ring has been cleared somehow
3. The driver ring and FPGA queue are always 1 on 1 mapping. User needs to map the higher level Linux priority to the driver ring idx instead of FPGA queue idx
4. Record the information about which FPGA queue (driver ring) has stopped which Linux priority before, and do exhausted search after a packet is sent (in the interrupt routine) to wake that Linux priority queue (in mac80211) up
5. Reserve more room before the FPGA queue full to adopt the last packet before we decide to stop the mac80211 queue. In this way, the last packet before the queue stop will still be put into FPGA and is expected to be sent (not lost/drop actively)

Fix the AMPDU reporting bug in tx interrupt:
...
When pkt_cnt is 1, it is also possible the aggregation case (single packet aggregation). So the reporting type (non aggregation or aggregation) should be decided automatically based on a dedicated use_ht_aggr flag instead of pkt_cnt, otherwise the Linux minstrel_ht link adaptation can not get correct TX status report in the aggregation case and will keep using the lowest MCS0

Make the freq/band report in openwifi_rx_interrupt from our driver internal variable instead of Linux setting. The latter might be asynchronous and cause issue: if the received management frame has wrong freq/band info, the Linux mac80211 might reject some state or have issue according to Linux kernel doc somewhere

Calculate the duration/id field in driver:
...
Linux only sets that field for non-ht, and leaves the field blank for ht. Linux expects lower level set it. This is realized after checking the mac80211 source code. After studying the duration/id field of COTS WiFi chip by wireshark, we calculate it in driver sdr.c gen_ht_duration_id(). The concrete logic/method of the calculation is in the comments of the function gen_ht_duration_id().
