[Madwifi-devel] Not able to match radar pattern

[Deep Shah]

Hi All,

I am not able to match radar pattern while streaming FCC DFS test video
from AP to station.

I have enabled DFS support on my madwifi driver in AP. I have connected one
station to this AP. I have connected laptops on both the side, behind AP
and behind station. I am streaming FCC testing video which will generate
radar pattern from laptop (behind station) to another laptop (behind AP).

The driver is able to detect that some radar pattern is there but it is not
able to match it due to some threshold values. Can you please help me out
from this situation. Please find below logs for the same.
