to set custom clock rate or bandwidth for Alfa wifi cards.

[alimp5]

at first, greetings and thanks to Aircrack-ng and RTL88xx developers and testers teams.

in Qualcom Atheros wlan/bluetooth chips like QCNFA435 M.2 on laptops we can change bandwidth to 5MHz, 10MHz, 20MHz, 40MHz and capture wifi data by kismet linux tool.
especially: 5 MHz and 10 MHz.

The following command allows Kismet to scan Wi-Fi channel 1 through 177 (consisting both 2.4 GHz and 5.8 GHz frequencies) at a 5 MHz bandwidth:
kismet -c adapter:channels = "1W5, 2W5, 3W5, 4W5, 5W5,...., 12W5, 140W5, 149W5, 153W5,....,177W5"

but in Alfa wifi cards like Alfa AWUS036ACH we are not able to set lower bandwidth (5MHz and 10MHz) to capture wifi data.
because the clock rate of some devices works on 5 or 10 MHz.
i want to capture and see data frames of them like MAC address and other public info.

I'm thankful if it's possible plz enhance the driver code or help me for solving this issue.

thanks a lot.
