Fixed typo in sdr.c

Fixed errors during compilation of OpenWRT kernel modules

Avoid rfkill turn off wifi after manual tx attenuation setting

NO code change. Formating

Necessary sdr.c change for ADI kuiper release

Though the SIFS definition in 2.4GHz is 10us, the actual gap is still 16us:
1. Confirmed by CMW270 in OFDM mode (10us is for 11b where viterbi decoder is not needed)
2. See Signal Extension in 18.3.2

Change the cca threshold to -62dBm. Seems help a lot in 2.4GHz

Fix the rssi_correction for WiFi 6E channel (close to 6GHz)

Easier way to set arbitrary trx frequency via register rf 1 and 5:
Create helper function ad9361_tx_calibration() and openwifi_rf_rx_update_after_tuning() for frequency tuning. No matter it is from Linux request or rf register 1 (Tx freq override MHz) and 5 (Rx freq override MHz)

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.

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

Align rx ring init to the new pkt existing flag inserted by FPGA

Add dmesg printk flag in sdr.h and use it in openwifi_rx-interrupt() accordingly

Move the location of hdr/addr1/addr2 in openwifi_rx_interrupt() preparing for statistics usage

Add more info when the rx pkt content is abnormal in openwifi_rx_interrupt()

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
