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().

Remove unnecessary ht aggr related flag reset:
...
Don't need to reset _prev variables every time when it is not ht aggr qos data. Reason:
1. In 99.9999% cases, the ht always use qos data and goes to prio/queue_idx 2. By not resetting the variable to -1, we can have continuous aggregation packet operation in FPGA queue 2.
2. In other words, the aggregation operation for queue 2 in FPGA won't be interrupted by other non aggregation packets (control/management/beacon/etc.) that go to queue 0 (or other queues than 2).
3. From wired domain and upper level ( DSCP, AC (0~3), WMM management, 802.11D service classes and user priority (UP) ) to chip/FPGA queue index, thre should be some (complicated) mapping relationship.
4. More decent design is setting these aggregation flags (ht_aggr_start) per queue/prio here in driver. But since now only queue 2 and 0 are used (data goes to queue 2, others go to queue 0) in normal (most) cases, let's not go to the decent (complicated) solution immediately.

- - bb_gain 290 work for 11a/g all mcs
- - bb_gain 290 work for 11n mcs 1~7 (aggr and non aggr)
- - bb_gain 290 destroy 11n mcs 0 long (MTU 1500) tx pkt due to high PAPR (Peak to Average Power Ratio)
- - bb_gain 250 work for 11n mcs 0
So, a conservative bb_gain 250 should be used
