Fixed typo in sdr.c

Fixed errors during compilation of OpenWRT kernel modules

Avoid rfkill turn off wifi after manual tx attenuation setting

Remove unused lines

Fix typo of printing in tx_intf.c

Too many dmesg while running side_ch:
Remove them

Disable eifs_trigger_by_last_tx_fail by default:
Standard does not ask so

Add sysfs to support xpu reg 6 bit27 26:
bit27 to disable eifs triggered by last rx fail
bit26 to disable eifs triggered by last tx fail

NO code change. Formating

Let lbt sdrctl command show richer info for set_lbt_th.sh

Change the initial sensitivity th from -95 to -85:
-85 is a good tradeoff between sensitivity and false alarm
-95 will result in lots of non necessary decoding action (false alarm), and sometimes it

Change the initial sensitivity th from -95 to -85:
-85 is a good tradeoff between sensitivity and false alarm
-95 will result in lots of non necessary decoding action (false alarm), and sometimes it leads to abnormal receiver state (stuck, etc)
-95 should be set manually while doing conductive test with wifi tester

Add driver support for euqalizer monitor:
When the equalizer out is too small (48 out of 52/56) for SIGNAL decoding, watchdoc will reset the receiver

Add side_ch driver build into make_all.sh

Adapt the side channel support for kuiper

Necessary change for scripts of driver building

Necessary sdr.c change for ADI kuiper release

We do not maintain our own (modified) ad9361 driver anymore! The original ad9361 driver in the Linux kernel tree can be used with some extra EXPORT_SYMBOL.

Add/Set the default fft_win_shift of new openofdm_rx to 1, which gives better throughput while receiving udp traffic

Remove unnecessary reg code in tx_intf.c

Refactor initial all open slice setup in xpu.c

Remove unnecessary code in xpu.c

Format sdr.h

Refactor a bit RING_ROOM_THRESHOLD/MAX_NUM_HW_QUEUE/MAX_NUM_SW_QUEUE

Refactor according to ...
Some xpu registers are removed

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
